I tried to write to linear FLASH cards by simply doing 'cat somefile >/dev/mem0c0c' resp. 'cat somefile >/dev/mem0c0b'. This does not work at all for several types of flash-cards I tested. Technical data: Debian 2.1 on Toshiba Libretto 100 Kernel 2.2.13 PCMCIA modules 3.1.13 (also tested with 3.1.2) Flash cards: e.g. KingMax 4MB (PPS-004MSR) with Iflash2+ Sorry, no logging output. It failes silently. Can anyone tell me whether I do something substantially wrong or is this a driver bug?
