Hi,
I remember... you were the one who brought hardware to the workshop.
Yep, thats me. :-)
My first problem it that flashrom does not support my flashchip.
But I hope I can fix this. :-) Patch attached.
Thanks for the patch. Unfortunately it seems your mailer wrapped the
patch. Thunderbird users either
- have to attach the patch or
Done
In theory, this should not happen. In practice, old or extremely cheap
flash chips can have sticky bits after a few erase cycles. I think the
risk for your board is almost zero.
I thought so, but want to be sure.
I'd like to do that, but the patch was so mangled that I had problems
reading it. It looks like you put vendor and device ID together in
AMIC_A49LF040A. The vendor ID you want is probably AMIC_ID_NOPREFIX.
OK, I changed that.
