[U-Boot-Users] Problem with PXA PCMCIA & (IDE) CF

[U-Boot-Users] Problem with PXA PCMCIA & (IDE) CF

[Rodolfo Giometti]

Hello,

on my custom board I have 2 PCMCIA slots. After pcmcia init I get:

equantum> pinit on
 
            Fixed Disk Card
            IDE interface 
            [silicon] [single] [sleep] [standby] [idle] [low power]

but when I do "ide reset" I get:

  Device 2: ide_outb (dev= 2, port= 0x1f6, val= 0xe0) : @ 0x200001f6
ide_inb (dev= 2, port= 0x1f2) : @ 0x200001f2 -> 0xd1

ide_inb (dev= 2, port= 0x1f7) : @ 0x200001f7 -> 0x51
Error (no IRQ) dev 2 blk 0: status 0x51

So, the CF is recognized but when the system tries to read first
sectors something goes wrong!

Any suggestions?

Rodolfo

This happen in the true ide mode when the timings are wrong so maybe
you have the same problem in pcmcia mode.
