Hi Coreboot Team,
Am trying flashrom 1.2 on W25R256JVEIQ NOR flash. Datasheet below https://www.mouser.ie/datasheet/2/949/Winbond_Electronics_Corporation_110120...
Flashrom supports below winbond DEVID's but not W25R series?
In Ubuntu /sys/class/mtd0 does not exist error is seen
#define WINBOND_NEX_W25Q40_V 0x4013 /* W25Q40BV; W25Q40BL (2.3-3.6V) */ #define WINBOND_NEX_W25Q80_V 0x4014 /* W25Q80BV */ #define WINBOND_NEX_W25Q16_V 0x4015 /* W25Q16CV; W25Q16DV */ #define WINBOND_NEX_W25Q32_V 0x4016 /* W25Q32BV; W25Q32FV in SPI mode (default) */ #define WINBOND_NEX_W25Q64_V 0x4017 /* W25Q64BV, W25Q64CV; W25Q64FV in SPI mode (default) */ #define WINBOND_NEX_W25Q128_V 0x4018 /* W25Q128BV; W25Q128FV in SPI mode (default) */ #define WINBOND_NEX_W25Q256_V 0x4019 /* W25Q256FV or W25Q256JV_Q (QE=1) */ #define WINBOND_NEX_W25Q512JV 0x4020 /* W25Q512JV */ #define WINBOND_NEX_W25Q20_W 0x5012 /* W25Q20BW */ #define WINBOND_NEX_W25Q40BW 0x5013 /* W25Q40BW */ #define WINBOND_NEX_W25Q80BW 0x5014 /* W25Q80BW */ #define WINBOND_NEX_W25Q40EW 0x6013 /* W25Q40EW */ #define WINBOND_NEX_W25Q80EW 0x6014 /* W25Q80EW */ #define WINBOND_NEX_W25Q16_W 0x6015 /* W25Q16DW */ #define WINBOND_NEX_W25Q32_W 0x6016 /* W25Q32DW; W25Q32FV in QPI mode */ #define WINBOND_NEX_W25Q64_W 0x6017 /* W25Q64DW; W25Q64FV in QPI mode */ #define WINBOND_NEX_W25Q128_W 0x6018 /* W25Q128FW; W25Q128FV in QPI mode */ #define WINBOND_NEX_W25Q256_W 0x6019 /* W25Q256JW */ #define WINBOND_NEX_W25Q128_V_M 0x7018 /* W25Q128JVSM */ #define WINBOND_NEX_W25Q256JV_M 0x7019 /* W25Q256JV_M (QE=0) */ #define WINBOND_NEX_W25Q32JW_M 0x8016 /* W25Q32JW...M */ #define WINBOND_NEX_W25Q64JW_M 0x8017 /* W25Q64JW...M */ #define WINBOND_NEX_W25Q128_DTR 0x8018 /* W25Q128JW_DTR */ #define WINBOND_NEX_W25Q256_DTR 0x8019 /* W25Q256JW_DTR aka W25Q256256JW-IM */
Is anyone aware whether the specific DEVID not supporting causes /sys/class/mtd0 does not exist?
Thanks for your time!
