I get (randomly): Found Winbond flash chip "unknown Winbond (ex Nexcom) SPI chip" (0 kB, SPI) on ch341a_spi. Found Generic flash chip "unknown SPI chip (RDID)" (0 kB, SPI) on ch341a_spi. Found Winbond flash chip "W25Q64.W" (8192 kB, SPI) on ch341a_spi.
Finding the correct chip or not seems to have little or nothing to do with the physical contact to the chip. […] Again, the hex codes for the failures seem pretty random and are different each time I try the command.
Hi Marius,
it is indeed random, because you apparently pick up lots of noise. Please see https://flashrom.org/Common_problems and https://www.flashrom.org/ISP Which voltage translator/adapter are you using?
