OK, I have a start on this problem. I changed cmd_ide.c as follows:
/* We only need to swap data if we are running on a big endian cpu. */ /* But Au1x00 cpu:s already swaps data in big endian mode! */ #if (defined(__LITTLE_ENDIAN) && !defined(CONFIG_AU1X00)) || \ (!defined(__LITTLE_ENDIAN) && defined(CONFIG_AU1X00)) #define input_swap_data(x,y,z) input_data(x,y,z) #else static void input_swap_data(int dev, ulong *sect_buf, int words) { volatile ushort *pbuf = (ushort *)(ATA_CURR_BASE(dev)+ATA_DATA_REG); ushort *dbuf = (ushort *)sect_buf;
while (words--) { #if defined(CONFIG_AU1X00) *dbuf++ = swab16(*pbuf); *dbuf++ = swab16(*pbuf); #else *dbuf++ = ld_le16(pbuf); *dbuf++ = ld_le16(pbuf); #endif } } #endif
Now when I boot the little endian u-boot it sees the CF card as:
Device 0: Model: SanDisk SDCFB-256 Firm: Vdg 8.21. Ser#: 114409E1903P1010 Type: Removable Hard Disk Capacity: 5376.8 MB = 5.2 GB (11011840 x 512)
Everything is correct except for the capacity. The big endian load has the correct capacity:
Device 0: Model: SanDisk SDCFB-256 Firm: Vdg 8.21. Ser#: 114409E1903P1010 Type: Removable Hard Disk Capacity: 245.0 MB = 0.2 GB (501760 x 512)
Is there somewere else that reads need to be swaped as well?
