I am asking this question once more since my previous try -- right before the Christmas break -- did not elicit any responses! ;~)
Without PCI support configured in the kernel, the CompactFlash card is discovered and configured by the kernel. With PCI support configured in the kernel, it fails to discover the CF card through the pata_platform driver. (Note that both PCI and CF work fine on this same board with the generic IDE driver!) There are only two differences that I notice between the two kernel setups that might be significant: 1.) The libata virq changes from 19 to 20. 2.) The isa_io_base changes from 0x0 to 0xfcfff000. Are either of these two changes significant? I am using the "arch/powerpc" kernel, version 2.6.20.21. The CF is wired directly to the local bus in True IDE mode. I have some debug info included in my previous message at: http://www.nabble.com/CONFIG_PCI-interaction-with-pata_platform-driver-on-MPC834x-board-tc14457502.html TIA! -- Johns _______________________________________________ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
