For serial NOR flash, NAND flash and DataFlash devices a custom RAMCode is needed since the connection of the flash to the CPU differs from device to device. Do I have to write the low level read and write routines or are these already done somewhere in the HAL libraries? Further information regarding this can be found here: J-Flash and Flasher are using a CRC. The Basic Command Set (BCS) is a group of commands that have been used for years on Intel’s and other vendors’ legacy products. sample projects and describes J-Flash’s menu structure in detail. The specified CPU core ID does not match with the one read from the target CPU. Please note, that the initial CRC used for the calculation is 0x00000000 (some calculators use 0xFFFFFFFF). This allows device-independent, JEDEC ID-independent, and forward- and backward-compatible software support for the specified flash device families. We recommend J-Flash or Flasher for production grade programming needs. project is located. For more … An individual or series of sectors may be selected from the predetermined valid range. J-Flash is a stand-alone flash programming software for PCs running Windows, Linux or macOS. In this case Next SN needs to be set to 0, since programming should be started with the serial J-Link comes with a set of highly speed-optimized built-in flashloaders which allow fast download of applications, directly into the flash memory of your target system. CFI compliant NOR flashes), the organization needs to be specified. In order to find out if special handling Prepares a connected Flasher for stand-alone mode using the current project and the data file which had focus most recently. Delay before start defines the delay (in ms) after enabling the target power supply and Opens and/or sets the focus to the log window. The CRC is calculated over all sectors which are selected in the current project, Everything that is not covered by the data file (gaps in the data file, unused sectors etc.) For some devices, the actual CPU clock frequency in Hz of the MCU is required to guarantee Contains a list of the most recently open project files. Ensure the specified core ID is correct for the used target CPU. The latest list of supported flash devices can always be found on our website: Flash memory can only be influenced by altering the data file. Make sure the memory sector is unlocked before programming or erasing. NOR Chip Drivers. A custom init sequence can be created or updated in the Init. how to proceed. The industry leading J-Link has been subjected to a flash programming speed comparison against various debug probes. If you are considering the use of a device other than those found in this test, we urge you to ask the supplier for their flash programming numbers before making the move. The device will be supported in similar fashion as all the devices supported already. logfile contains the same messages as the log window output of J-Flash. If this option is checked, J-Flash will connect to J-Link / Flasher over the USB port. Opens a J-Flash project file. The “JTAG scan chain information” box allows to configure a JTAG scan chain with multiple The main window of J-Flash contains seven dropdown menus (File, Edit, Target, Options, View, Help). Any common flash interface (CFI)-compliant flash device connected to the FPGA can be programmed using the Nios II integrated development environment (IDE) flash programmer. : +49-2173-99312-0 Fax: +49-2173-99312-28, Boston area Which line J-Flash will read at the next programming cycle is configured via the Next SN Saves a .DAT file for stand-alone mode using the name and location given. Does nothing. Performs a sequence of steps, which can be configured in the Production tab of the Project settings. In a scan chain configuration with multiple devices, the TCK and TMS lines of all JTAG devices are connected, while the TDI and TDO lines form a ring. Make sure the flash memory is unlocked before programming or erasing. In order to use the serial number feature, the J-Flash project has to be configured to enable programming a serial number at a specific address. Free download. I have not written any specific drivers or code for the flash, I am using CFI probe to take care of all those things. The target flash memory or the bus organization is not yet supported. All important options are available in NORFLASH_WRITE_FAILURE Flash write/erase failure. HP NC375I. This code provides support for one of those command sets, used on chips including the AMD Am29LV320. The length of the serial number (in bytes) which should be programmed. Some styles failed to load. A good example of a typical init sequence is the init sequence of an AT91SAM7 CPU. The target memory was not empty during blank check. The Common Flash Interface specification was developed by Intel, AMD and other flash manufactures that provides a universal method for probing the capabilities of flash devices. J-Flash requires a J-Link / Flasher as an interface to the target hardware. Discharge target on disconnect causes a discharge of any capacities left on the target Actions performed by "Production Programming", On "Erase selected sectors" / On "Erase chip". This is especially useful when testing different configurations. CFI compliant (Common Flash Memory Interface, a standard published by AMD), use CFI command set 2, 8 bit wide or; 16 bit wide. PDF: 09005aef846b89e3/Souce: 09005aef846b89f0 Micron Technology, Inc., reserves the right to change products or specifications without notice. Please note that no erase / blank check is performed prior programming so the flash is assumed to be in an erased state. MSC driver. Please refer to Project Settings. The JEDEC Solid State Technology Association defines industry standards for semiconductor devices, with CFI being Because of that, it is necessary for J-Flash to update the project information accordingly - otherwise it cannot open the project file. This allows parameterization of known and future flash Read/Write/Erase control interfaces. This chapter provides some background information about specific parts of the J-Flash Checks if the internal variable is equal to 0. .hex, .mot, .srec, .bin and .elf support. be configured for SEGGER probes connected via Ethernet directly (e.g. Start line into serial number list file to get next serial number bytes, line increment, serial number size and address is configured in J-Flash production project settings. 133 Xiulian Road Writes data of an specified size to an defined address, reads the written data back and measures the up- and download speed. The flash download feature of J-Link supports programming of external CFI-compliant, parallel NOR flash devices, allowing these devices to be programmed either … wizard. The ULINKpro is limited to use with KEIL uVision. Using the Program and Erase maximum time specification stated in the device datasheet; Calculating the maximum Program and Erase time using CFI data; All Cypress Parallel NOR Flash products are CFI compliant. As you might have noticed, the NOR flash chip used by the handheld in Figure 17.2 is labeled CFI-compliant. Flasher can also operate as a normal J-Link.

A J-Flash project (containing the configuration). in the Project settings. The MSC (Mass Storage Class) driver supports USB host MSC devices (i.e., thumb drives or USB drives) via µC/USB-Host. This can either be done by the customer or by SEGGER (request quote: sales@segger.com). Still there are occasions, where support for a device is needed, that is not available yet. needs to be created by the user. - J-Link found 0 JTAG device. The recommend way of getting started with J-Flash is to use the Create New Project This chapter presents an introduction to J-Flash. Supported Flash Devices. This standard defines a signaling protocol that allows the host to reset the slaved Serial Flash device without a dedicated hardware reset pin. flash memory device. If I deselect automatic flash memory detection in the project settings, I cannot see the flash device: JFlash SPI, which I would use to connect the device in direct mode supports the device: J-Flash is not always forward compatible. Sets the RS232 OK signal of a connected Flasher. I was interested in partitioning it by hardcoding through the kernel. that the command set and feature set, etc., are identical with other SPI NOR FLASH manufacturers. Open Source Software. All command line options return 0 if the processing was successfully. Find below a table which describes the commands: The settings in this section are taken account for stand-alone configurations, only. Altera Corporation Avalon Tc. Verifies whether 16bit data on a declared address is identical to the declared 16bit data. remote system. REM Each process blocks its corresponding lock file as long as the process is alive. For more information about the different types of interface speed please see the chapter I tried all options, power cycling, multiple resets, unlock kinetis, etc. CRC of the user data in this file. Writes 32bit data of the internal variable to a given address. “Mask” are not taken into account when comparing the Code ID found by the J-Link / Flasher Saves the data file that currently has focus using the name and location given. Many microcontrollers require an initialization sequence for different reasons: The developer is able to use one driver for different flash products by reading identifying information from the flash chip. used here only to denote (optional) parameters. Verifies the data found on the chip with the data file. Overrides connection settings to USB S/N. It's possible that this initialization routine is failing and your flash device isn't being registered with the HAL. If no serial number list file is given, J-Flash allows to use a 1-4 byte serial number. See section MCU Settings for information about setting the core ID. Project files are available upon request so to reproduce these tests results (support@segger.com). If only a core family is selected, the core ID field can be modified. For some devices, special handling might be required. This process is called wear leveling. Enables JTAG checks. memory is too slow during programming. started with the command line parameter -help or -? Set the master and processor clock by writing to the Master Clock Register of the power management controller. J-Flash provides This device performs lowest among those tested. select little endian or big endian from the dropdown menu accordant to the device. If I deselect automatic flash memory detection in the project settings, I cannot see the flash device: JFlash SPI, which I would use to connect the device in direct mode supports the device: Logical OR combination of the internal variable with a given value. If the NOR flash device which is used is not CFI-compliant, the flash device has For connections via the J-Link In general, every CFI-compliant parallel NOR flash device is supported by J-Flash. Output of other compilers may be supported but is not guaranteed to be. If a device is not yet listed there, silicon vendors and end customers can add support for said device by themselves using the Open Flashloader feature. J-Trace See section MCU Settings. The compatible endianness of the selected device is set automatically if possible. and J-Link, a valid license is required. Reads back the data found in the selected sectors and creates a new data file to store this information. Tel. The EZ-Kits use a non-CFI flash, the AMD/Spansion AM29LV081B. This is done by enabling the Program serial number option as shown in the screenshot and table below: When starting the program process Target -> Production Programming, J-Flash will Without a license key Using smaller RAM block sizes may fix this problem. J-Link Commander) for this device. CFI flash requires that addresses be toggled from x555 to 0xAAA (byte operation) between each 8 bit word for write and erase instructions. look similar to the screenshot below. number bytes defined in the first line of the file. writing in the memory window can be used to change constants in flash), Flash breakpoints (unlimited number of breakpoints when debugging in flash), Any IDE (e.g. J-Link Remote Server overview. Connection Status Application log started - J-Flash V6.20h (J-Flash compiled… Login or register. can also be opened with any version of J-Flash newer than (i.e. Pay special attention to the following aspects: The interface clock frequency depends on several factors, e.g. Altera avalon cf regs.h The header file that defines the core's register maps. Reads back the data found in a range specified by the user and creates a new data file to store this information. The flash memory sector may be locked and programming or erasing the respective memory NORFLASH_NOT_CFI_DEVICE The flash is not CFI compliant. Creates a connection through the J-Link / Flasher using the configuration options set in the Project settings... of the Options dropdown menu. This is going to be an issue if your design uses on-board programming using a Danville dspFlash programmer or an ADI ICE. This allows device-independent, JEDEC ID-independent, and forward- and backward-compatible software support for the specified flash device families. Sets the path to the JLinkDevices.xml file. Microcontroller (internal flash) support. We are confident SEGGER will outperform all others. This release of the specification defines the basic Query interface for CFI-compliant devices. in the log window. In addition to its graphical user interface (GUI), J-Flash supports a command line mode as How do I correctly register my flash device (a standard AMD CFI flash)? The address the serial number should be programmed at. Executes the exit steps defined in the MCU settings. This Query structure attempts to define all the critical parameters relevant to a broad base of flash memory devices. The size of the generated data file can be defined. CFI-compliant NOR Flash Device Driver CPU: ARM Example: MXIC MX29LV640D T/B (Parallel, Top Boot Flash) Bootloader: u-boot-2008.10 ()Description: You can implement the driver in two different ways. And the best of all: This feature is free of charge. If 8 is selected as length, the serial number and its complementary is programmed at the given address. USB device stack A USB stack designed to work on any embedded system with a USB client controller. This option allows the user to mask out specified bits of the core ID. The Flasher ARM is designed for programming flash targets with the J-Flash software or stand-alone. The J-Link / Flasher can either be connected to the host system of J-Flash directly via USB, The position of the device to connect with J-Flash is selected from the Position dropdown After programming the serial number, J-Flash creates the _Serial.txt. A timeout occurs if the target is too slow during DCC communication or the target flash NORFLASH_WRITE_TIMEOUT Flash write/erase timeout. In order to use the serial number programming feature, the J-Flash project to be used as well as some files in the working folder Please refer to the Flasher documentation (UM08022) for more information regarding stand-alone mode. If you wish to support any device that is CFI-compliant, you need to enable this option. Community … This dialog is used to select and configure the flash device to operate with. The interface speed after init is used to communicate after executing the custom initialization If Perform blank check is checked, a blank check will be performed before an erase. In general, the J-Link DLL comes with a built-in device database that defines which devices are supported. The Comment text box should be used to enter a The startup dialog provides the following options: If “Do not show this message again.” is checked, J-Flash will execute the option currently The SWD speed has been selected at the maximum possible for each debug probe. Recently, we heard from a customer that the 29LV081B is EOL (end of life). Some CPUs (e.g. To program internal flash devices, the respective microcontroller must be selected in the However to actually program devices via J-Flash create a serial number file named as _Serial.txt . J-Flash supports programming of serial numbers into the target in two ways. First of all, make sure the target is actually connected to J-Link. In order to generate an expressive logfile, set the log level to “All messages” (see section Global Settings for information about changing the log level in J-Flash). The command line interface Therefore, the J-Link Software and Documentation Pack already includes some example projects for us with the following information: Once we received this information we will try our best to solve the problem for you. For a list of all valid actions which can be used in an init Can be used as additional space to insert comments. the init sequence, check the JTAG speed, and ensure the correct flash type is selected. the project file should open in both versions without any issues. In the process of auto-updating the J-Flash project file, some information (like the selection of sectors a flash bank) may get reset. In this section, the action J-Flash performs on startup can be selected. Secures the device if supported by algorithm. This should This If this option is checked, J-Flash will connect to J-Link / Flasher via TCP/IP. The tests with J-Link were performed with J-Link software version 4.59a and using J-Link flash loader. example to initialize the PLL, disable the watchdog or define the wait states of the flash. NORFLASH_WRITE_FAILURE ... Return a pointer to a NORFLASH_Info_TypeDef, which contain vital flash device information. All CFI-compliant devices use the same 1-cycle command sequence to place Flash in CFI query mode1 regardless of Flash manufacturer or sup-ported command set. PLL initialization, external bus interface initialization, script files, etc…). Writes 32bit data of the internal variable to a given address in the data file. It provides an overview of the included In the following a small sample is given how to setup J-Flash for serial number programming. As long as the project file format has not changed from one version to another, The address is ignored (don't care) for all commands, which avoids the 32 bit packing issue. In the Action Type dropdown menu all available actions are listed. When that is that case, the message box shown below will appear. execution of the batch file stops and the following commands will not be processed.
