Hello and Happy New Year,
a couple of days ago I acquired an old GeodeLX-based thin client TONK-1202/ТОНК-1202 (cyr) for a purpose to put coreboot on it, because board is very simular to existing ones in the coreboot tree and there should be no big deal to make a port. Aside from very funny issue that I am not able to boot modern 2.6.18+ i386 Linux kernel on it (ALIX Geode board said to have same issue , but it has been reportedly fixed by a vendor bios update), all other Linux variants (2.4.xx and 2.6.13) and NetBSD 7.0 are somehow messing with the internal interface, with no positive outcome as a result:
./flashrom -p internal:laptop=this_is_not_a_laptop -c W39V040FB -r bios.bin -V .... Probing for Winbond W39V040FB, 512 kB: probe_jedec_common: id1 0x25, id2 0x6b, id1 is normal flash content, id2 is normal flash content No EEPROM/flash device found ...
NetBSD 5.1 with same flashrom version working just well, I was able to read the chip contents and write them back without any issues. This is not a blocker, as I would stick to the external programmer anyway, but probably worth investigating as a regression - monolithic nature of NetBSD releases and very limited board performance would not allow to bisect this easily, so it`s better to narrow a debug field, if possible, in advance.
