  • samsung flash chip not supported?

    i have reciently buy jlink for my project.
    i checked j-flash able to communication with mem command.
    but jlink arm not able to work all showing this.

    Using adaptive clocking instead of fixed JTAG speed
    - Initializing CPU core (Init sequence) ...
    - Initialized successfully
    - Using adaptive clocking instead of fixed JTAG speed
    - J-Link found 1 JTAG device. Core ID: 0x220B10E1 (ARM9)
    - ERROR: Identify: Unsupported flash type / bus width (210800). Please contact info@segger.com
    - ERROR: Unable to identify Flash
    - ERROR: Failed to connect

    i have send email also.
    flash chip is K5L6331CAA
    and i don't have chip datasheet.
  • Hi all,

    without any datasheet it is a bit hard to say, how to support these flashes.
    What would be essentially needed is information about the command set to erase/program the flash and the sectorization.

  • sorry for late reply.
    jflash command line may help to just dump and rewrite?

    no datasheet for this at all.
    there are some similar ic may possible to work on this chip?

    one more i have Toshiba chip showing same.

    CFI details also not possible to read anything possible on this case?
  • Hi Austin,

    as previously mentioned:
    Without a datasheet of the device which gives information about CFI-compliance, command set, sectorization etc.
    unfortunately, there is nothing we can do here.

    Best regards

  • Hello.
    i have folloing details for my one of pcb.

    SAMSUNG K5L3217AB
    ID : 00EC:2609, Samsung

    Device : 0x00400000 (4194304)
    Flash Interface description : 0x0000 (0)
    Buffer size for buffered write : not supported
    Number of Erase Block Regions : 2
    Number of Blocks in Region #1 : 8
    Block size in Region #1, bytes : 0x00002000
    Number of Blocks in Region #2 : 63
    Block size in Region #2, bytes : 0x00010000
    Total number of all Blocks : 71

    can you tell me details how do i update flash.csv with this info?

    i think nor device you just need Geometry information for this chip which i provide you.
    so can you please let me know possible solution to update jlink csv for this chip.

    this info is from tool which support this chip perfectly.
    i want to make it supported and many more chip in jlink so i can make jlink better then other tools.

    regards
  • Hi,

    this flash does not seem to be CFI compliant, otherwise auto-detection should work.
    If it is not a CFI-compliant device having the datasheet is the minimum requirement to implement support for this flash device.
