Hi I'm trying to get IDE working via PCMCIA on a custom board wih a MPC870 CPU. I have a SanDisk 128MB CF card and a CF to PCMCIA adapter. I have it partly working. The bootloader (RedBoot) dont configure the PCMCIA registers so I took the initialization code from U-Boot and added it to m8xx_ide_init. The card is identified but no IDE device is found. I have run out of options to try and would be greatful for any ideas.
