flash.h suggests that the manufacturer might be ASD:
#define ASD_ID 0x25
I did a search and found that the flash chip should be 2Mb. Therefore I guess the flash chip is AE29F2008. Could you verify that?
Right. Removing the sticker sure helps. Atmel AT49F002NT is written on the chip, which is supposed to be supported by Flashrom.
From this[0] page, it seems that AE29F2008 and AT29C020 behave in
similar way. If you are trying to read the content, maybe you can try a force read.
$ sudo flashrom -f -r -c "AT49F002(N)T" test.rom Calibrating delay loop... 490M loops per second, 100 myus = 174 us. OK. No coreboot table found. Found chipset "VIA VT8235", enabling flash write... OK. Probing for Atmel AT49F002(N)T, 256 KB: probe_jedec: id1 0x25, id2 0xe4 No EEPROM/flash device found. Force read (-f -r -c) requested, forcing chip probe success: Probing for Atmel AT49F002(N)T, 256 KB: Found chip "Atmel AT49F002(N)T" (256 KB) at physical address 0xfffc0000. Force reading flash... done.
test.rom also has not only null written to it, so it seems to be working.
What could be done, that the chip is auto-detected?
Hope I am giving some useful information.
Yes. Thanks a lot. I should have figured this out by myself.
Anything else I can do?
Thanks,
Paul
