I have a PC Engines apu2d4 running NetBSD 8 (amd64), and would like to
update coreboot/etc. on it. I searched the list (perhaps not well) and
didn't find any reports of success, although I realize things are
generally expected to work so success might well go unreported.
I am using flashrom 1.1 as built from pkgsrc.
I was able to read the existing bios without issues as:
flashrom --programmer internal -r 20200301-readflash.rom
Before I try to write, I am wondering if anyone has successfully done an
apu2 bios update with flashrom under NetBSD 8 amd64?
(I have a debricking adaptor (spi1a) and will prepare a Linux flashing
image on USB before trying myself, whether I not a get a report of
success.)
Thanks,
Greg
Hello,
I wanted to read/write a chip "p25q80h" with flashrom and a ch341a
programmer and flashrom told me to help you by mailing the attached
output to this address to add the chip.
If you need more information, feel free to reach out to me.
best regards,
Michael Kerscher
Greetings!
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.
Regards,
Sergio
Hi
I need to reprogram the firmware on a WD HDD with SOIC8 Winbond chip supported by flashrom. I tried reading in-circuit but my programmer does not detect it (other chips work fine). Probably other components are drawing voltage so I disconnected Vcc and tried to power it through regular SATA connectors which didn't work. Do you have any recommendations how to workaround this issue? Will supplying power through 3.3V Vcc and SATA connector at same time fry the chip?
Thanks for your help

Hi I tried bios flashing and it ran perfectly till it verified at the end of writing the flash

At first I got a fail reading because I disconnected it somehow, then it worked and got this at the very end thanks!
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,
How are you?
I am trying to coreboot an Asus A88XM-E. The chip on that motherboard is GD25Q64(B), which I execute sudo flashrom --programmer ch341a_spi -w coreboot.rom, I got this error:

I got new GD25Q64 chips from aliexpress. The verbose version is like this:
Found GigaDevice flash chip "GD25Q64(B)" (8192 kB, SPI).
This chip may contain one-time programmable memory. flashrom cannot read
and may never be able to write it, hence it may not be able to completely
clone the contents of this chip (see man page for details).

Hello,
I am rying to update the BIOS on my 10-yr-old laptop. Per the output of the flashrom command, I am including the output I received:
