I've been playing around with the 8xxrom pcmcia code and done some simple CIS parsing code. I am using a ADS860 Rev B board. The MMU is off, the code is running from flash. I've done a workaround for the bugs in the MACH-circuits. The code works fine with: SanDisk CompactFlash Mitsubishi CompactFlash Ericsson Pcmcia V34 Modem The following card does not work: Viking components CompactFlash. My code reads the attribute space on each card and parses the tuples. The problem is that the Viking card gives me correct CIS sometimes, but mostly crap (I guess some kind of test-pattern). This leads to no end-of-cis marker, which is bad. I browsed the net and found that Paul Rubin have had a problem that seems related: http://hyper.stanford.edu/HyperNews/get/pcmcia/ataide/39.html People has experienced problem with Viking components before: http://www.goof.com/~mmead/dc120/mail-archive/9806/msg00026.html I've contacted Viking support but they told me that they didn't do that kind of tech-support. Another thing is that if I stick to access the ATA registers all CompactFlash cards (even the Viking) work. Any ideas, workarounds, similar problems?
