We validated the hardware by reading the Compact Flash through the System ACE controller from u-boot.But we find difficulties from the kernel. We applied the system ACE driver patch onto linux-2.6.16-2. We tried in both polling and interrupt mode. Following are the main changes we did in the driver: 1. System ACE controller base address configuration (xparameters_ml300.h, adapter.c) 2. Endianess (xsysace_l.c) 3. IRQ (xparameters_ml300.h) With these changes we are able to read/write to the compact flash controller. But we see difficulties while reading the compact flash. 'Fdisk' command lists the partition details first time we run the command. While issuing the Issuing the command second time, it exits to the command prompt without displaying the partitions. Also we coudn't succeed in mounting the system. Could someone give us some pointers to debug in this issue.
