issue with Micron N25Q128

[Shih-Chieh Huang]

Hi,

I am having problem programing N25Q128 using flashrom0.9.7.  I got  the following errors from erasing  address at 0x83f000. I have tried different boards and they failed at the same locations.  There are three versions of N25Q128, uniform, top, and bottom. Only the 8 first/last sectors of top/bottom version supports subsector erase. But, from N25Q128 configuration in flashchip.c, it first tries SSE (0x20) for the entire chip. Could  it be the problem? Is there a fix for this? Thank you very much.

Found Micron/Numonyx/ST flash chip "N25Q128..3E" (16384 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).
Block protection is disabled.
Flash image seems to be a legacy BIOS. Disabling coreboot-related checks.
Reading old flash chip contents... done.

FAILED!
Uh oh. Erase/write failed. Checking if anything changed.
Good. It seems nothing was changed.
Writing to the flash chip apparently didn't do anything.
This means we have to add special support for your board, programmer or flash
chip. Please report this on IRC at chat.freenode.net (channel #flashrom) or
mail [e-mail], thanks!

Hello,

sorry for the late reply. I believe your problem is the chipset
configuration. The most interesting parts of your log are missing... if
you still need help, please send a complete verbose log (feel free to
redact the DMI data if you have to).

[Shih-Chieh Huang]

Stefan,

Thank you for helping me on this. We disable the security from AMI BIOS temporary to walk around this. In the future, we will need to re-enable the security feature. I was wondering if flashrom has plan to support such feature.  Thanks.

Regards,
Cliff

There are three versions of N25Q128, uniform, top, and bottom. Only the 8 first/last sectors of top/bottom version supports subsector erase. But, from N25Q128 configuration in flashchip.c, it first tries SSE (0x20) for the entire chip. Could  it be the problem? Is there a fix for this? Thank you very much.

Hello,

sorry for the late reply. I believe your problem is the chipset configuration. The most interesting parts of your log are missing... if you still need help, please send a complete verbose log (feel free to redact the DMI data if you have to).

Hello,

it depends on which write protection you are referring to?

As far as I know not all of them can be disabled from a running OS.
Others require a handshake with SMM code that is firmware
vendor-specific and they won't tell us how that works (even if it would
be secure to do so due to cryptographic signatures in the images). We
would like to support these kind of things but without public
documentation this is not feasible. It would be great if you, as a
customer with a voice that might not be ignored like our, could lobby
for a solution in these cases.

Everything else will be happily supported if we get to know about it
and there is documentation :)
