I am able to detect my flash chip when I use the command:

Code: [Select]
    ./flashrom -p ft2232_spi:type=arm-usb-ocd -c EN25Q64


If use the below command to write binary file to the flash memory using JTAG - ARM-USB-OCD debugger for my target board RT5350F-OLinuXino-EVB, I am getting an error.


Code: [Select]
    ./flashrom -p ft2232_spi:type=arm-usb-ocd -w FlashImage_RT5350F_OLinuXino_EVB.bin

The error is:

Quote
    Found Eon flash chip "EN25Q64" (8192 kB, SPI) on ft2232_spi.
    ftdi_write_data: -110, usb bulk write failed
    send_buf failed before read: 1
    Reading old flash chip contents... ftdi_read_data: -110, usb bulk read failed
    get_buf failed: 1
    FAILED.

Please let me know,

Thanks.

You can try the next command for reading the flash.

Code: [Select]
flashrom -p ft2232_spi:type=arm-usb-ocd,divisor=8 -VVV -r dat.bin
Be sure you have shorten the RST_RT pins.

unfortunately , with ARM-USB-OCD , i have this nice message :

Quote
EMS returned 0x00 0x00. probe_spi_rems: id1 0x0, id2 0x0
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

... with EVB or the SPI GPIO connection.
