Information function read

[Lukas Augustin]

Hi,

I would like to ask about read parametr. I have PC HP All-in-one and after
change SSD disk PC blackout, not even logo shown up, so i found
instructions how to write newer bios(because led double flash and that me
bios corrupted) using Arduino UNO to ROM_RECOVER bus.Firstly I try backup
old ROM used command: sudo flashrom -p serprog:dev=/dev/ttyACM0:115200 -r
old.ROM and after that I saw serial line sending data but after 10 minutes
LED TX turn off and at Terminal is still Reading flash.... after 30minute
waiting nothing happend. Will you advise me?

Thank you,

Hi Lukas,

hanging while reading is a bit strange but not impossible.

Please use the newest dev version:
git clone https://github.com/flashrom/flashrom.git

And build it at your own
(something like: navigate to the resulting flashrom directory, and do:
make
make install
)

After doing so run it again and check if problem still exists.

Btw: Before updating I would always make sure that reading works fine. i.e. run reading cmd twice and compare read results. Only if they do not differ, I´d recommend to write.

Regards,

Simon
