Hi Flashrom Team,

The DID 0x4019 which is for WINBOND_NEX_W25Q256_V 0x4019 /* W25Q256FV or W25Q256JV_Q (QE=1) */
supports W25R256JVEIQ flashpart

I think the issue is with table chipset_enables defined inside -> flashrom-master\flashrom-master\Chipset_enable.c
is not matching Elkhart Lake PCH ID which is causing

WARNING: No chipset found. Flash detection will most likely fail

 

Best Regards

Hi Flashrom team,

Am trying to flash on W25R256JVEIQ NOR flash

sudo flashrom -p internal -w coreboot_ehl_2609.bin

flash device is not found, hope it means W25R256JVEIQ NOR flash device is not supported by flashrom 1.2?

sudo flashrom -p internal -w coreboot_ehl_2609.bin
flashrom v1.2 on Linux 5.13.0-21-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).
WARNING: No chipset found. Flash detection will most likely fail.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically

Thanks for your time!
