netbook hp 2133 mini :(

[Paweł Stawicki]

Hi,
I tried flashrom on my netbook with this result
No EEPROM/flash device found.

:(
netbook still works :)

I'm attaching the result of:
sudo ./flashrom -p internal:laptop=force_I_want_a_brick -V > flashrom.txt

The opmenu has opcodes 05 d8 03 02 c7 9f 01 90

And here flashrom complains about an opcode that should be present. Very
odd. We will need to investigate this.

Thanks for your report.

I suspect that we're not handling some lockdown correctly. Could you do
a short check for us?
Insert directly before ichspi.c line 1068:
ichspi_lock = 1;

Then please recompile and run again in verbose mode. I don't expect
success, but I think we have a good chance to learn more.

changed to:

spi_controller = SPI_CONTROLLER_VIA;
   ichspi_lock = 1;
   ich_init_opcodes();

return 0;
}

attaching  output:
ubuntu@ubuntu:~/flashrom$ sudo ./flashrom -p
internal:laptop=force_I_want_a_brick -V > flashrom2.txt
delay loop is unreliable, trying to continue
========================================================================
WARNING! You seem to be running flashrom on a laptop.
Laptops, notebooks and netbooks are difficult to support and we recommend
to use the vendor flashing utility. The embedded controller (EC) in these
machines often interacts badly with flashing.
See http://www.flashrom.org/Laptops for details.

If flash is shared with the EC, erase is guaranteed to brick your laptop
and write may brick your laptop.
Read and probe may irritate your EC and cause fan failure, backlight
failure and sudden poweroff.
You have been warned.
========================================================================
Proceeding anyway because user specified laptop=force_I_want_a_brick
