Thanks for creating such wonderful tool.
i would like to ask for a suggestion as developers of the tool will be the best one to ask. Basically i am trying to flash efi chip on imac, micronix MX25L6406E/MX25L6408E but just can't get any readings.... i got an working macbook with same chip and once i connect to it, everything works like charm. i was able to read file from working macbook 10 times(8/10 checksum matched!). So i can assume my setup is correct! But no luck reading same chip from imac motherboard.
Could you please suggest anything?
Could it be that: 1) because chip is on password locked chip is not readable? (doesn't make sense though, right?) 2) maybe chip is faulty? which is very unlikely 3) could it be because chip is on motherboard and unsoldering it would help? 4) i am currently reading chip with sudo flashrom -r oldefi1.bin -V -p linux_spi:dev=/dev/spidev0.0 maybe there is some additional arguments, i should try.
If you're positive it's the same chip, #3 might be the best option. Unfortunately, it's also the most dangerous.
