    Hey, long time no see GBATemp !

    I'm trying to read the Wii U Gamepad firmware in the 25Q256A chip to be able to fix it.
    Here is my setup so far :
    I'm using frser-duino using an Arduino Uno R3 along with flashrom (tried latest stable and master)

    So far I'm only getting :
    Code:
    [email protected]:~/dev/flashrom$ ./flashrom -p serprog:dev=/dev/ttyACM0:115200 -r gamepad.rom
    flashrom v0.9.9-109-ged098d6 on Linux 4.4.0-104-generic (x86_64)
    flashrom is free software, get the source code at https://flashrom.org
    
    Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).
    serprog: Programmer name is "frser-duino"
    serprog: requested mapping AT45CS1282 is incompatible: 0x1080000 bytes at 0x00000000fef80000.
    serprog: requested mapping MX25L25635F/MX25L25645E/MX25L25665E is incompatible: 0x2000000 bytes at 0x00000000fe000000.
    serprog: requested mapping MX66L51235F is incompatible: 0x4000000 bytes at 0x00000000fc000000.
    serprog: requested mapping N25Q256..3E/MT25QL256 is incompatible: 0x2000000 bytes at 0x00000000fe000000.
    serprog: requested mapping N25Q512..3E/MT25QL512 is incompatible: 0x4000000 bytes at 0x00000000fc000000.
    serprog: requested mapping W25Q256.V is incompatible: 0x2000000 bytes at 0x00000000fe000000.
    Found ST flash chip "unknown ST SPI chip" (0 kB, SPI) on serprog.
    ===
    This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE
    The test status of this chip may have been updated in the latest development
    version of flashrom. If you are running the latest development version,
    please email a report to [email protected] if any of the above operations
    work correctly for you with this flash chip. Please include the flashrom log
    file for all operations you tested (see the man page for details), and mention
    which mainboard or programmer you tested in the subject line.
    Thanks for your help!
    Read is not working on this chip. Aborting.
    
    References :
    I have a working Wii U Gamepad in case, but I would be able first to read the « not working » Gamepad chip before opening/tearing down the « working » one.

    Any help is appreciated, and by the way happy new year 2018 !
