Hi, here just some general information/advice: Use the latest flashrom version (current version 1.2: https://www.flashrom.org/Flashrom/1.2 ) For chip handling issues: https://www.flashrom.org/Board_Testing_HOWTO For electrical issues: Do read operation several times and check for equality. Touch the cable/wires before starting a new read operation in order to find out if the contacts are good. If all reads give you the same file there shouldn´t be any problem at electrical level. If you get diffs between the files you have an electrical problem -> check contacts, use as short cables/wires as possible and try a lower frequency (if programmer supports this; do not overvalue the impact of frequency on total programming time, for some programmers most of the time is lost on other stages like usb communication etc. ). Check again with several read runs. Regards, Simon Von: Nikos Mouzakitis <mzktsn@gmail.com> Gesendet: Dienstag, 19. Mai 2020 13:33 An: flashrom@flashrom.org Betreff: [flashrom] Is this an Error?
