CF卡驱动的问题

xinpascal

我最近在做一个CF接口的驱动,现在问题卡住了,还请大侠们多多指点.
硬件XA270平台,CPLD控制PXA270对CF接口的访问
软件:linux-2.6.9+pcmcia-cs-3.2.8
现象如下:
1.CD,STSCHG中断响应正常
2.卡的CIS信息通过dump_cis能正确读到,但是使用cardmgr时会出现ide-cs: ParseTuple: Bad CIS tuple错误
请大家帮我分析一下问题可能出现在哪些地方.
如果有大侠有意,此项目可以外包,这个问题对于一个有经验的驱动开发人员来说应该很容易解决的

附上现象:
##直接执行cardmgr:
[root@PXA270 root]#cardmgr cardmgr[833]: cannot access /lib/modules/2.6.9-intc1: No such file or directory
cardmgr[833]: watching 1 socket
cs: memory probe 0x0c0000-0x0fffff:<7>cs: pcmcia_socket0: read_cis_mem(1, 0x0, 2)
clean.
cardmgr[834]: socket 0: ATA/IDE Fixed Disk
ide-cs: ParseTuple: Bad CIS tuple
cardmgr[834]: get dev info on socket 0 failed: No such device
##先执行dump_cis,再执行cardmgr:
