Opcode 0x20 takes a 3-byte address and 0x1000000 is a 4-byte address, so this failure makes sense. You either need to use opcode 0x21 which is 4KiB erase with 4-byte address, or use the extended address register in the flash chip. I'm not sure how to do that (or if it's possible) with software sequencing on Skylake-D though... > I also try your suggestion and it also failed. > //=========================================================== > The following protocols are supported: Parallel, LPC, FWH, > Programmer-specific. > No EEPROM/flash device found. > Note: flashrom can never write if the flash chip isn't found automatically. > //=========================================================== I forgot to mention that for hardware sequencing you should either omit the chip option or set it to "Opaque flash chip", i.e. "./flashrom -p internal:boardmismatch=force,ich_spi_mode=hwseq -l allregion.xml -i bios -w Lightning_R01.2_test.bin -c "Opaque flash chip" -V -N" _______________________________________________ flashrom mailing list -- [email protected] To unsubscribe send an email to [email protected]
