note this is a 1.8V chip and that might be the cause of your problems. If you don't have a voltage adapter between your CH341A and the flash chip, a safety circuit in the flash will trigger and prevent erasing (as that would damage the chip at higher voltage). If you already have a voltage adapter, it might be a write-protection. Make sure that all the input pins have a defined state and that the /WP pin is at a high level. Hope that helps, Nico _______________________________________________ flashrom mailing list -- flashrom@flashrom.org To unsubscribe send an email to flashrom-le...@flashrom.org
