Dear sir :

I am now use cf card  in True IDE mode in uboot.I can read the identify imformation in the ide_init() function as follow . however when it run to the function---- init_part (&ide_dev_desc[i] ->ide_read()-> ide_outb (device, ATA_COMMAND,  ATA_CMD_READ);It show error, the error register value is 0x4 .What is the reason? Can you give me some advice?It seems that there is erro at first ,because the ATA_STATUS  is 0x51 at first!

you need to describe the exact hardware and software you're using, and the config settings you're using in your u-boot board config

I just uncomment this sentence  #define CONFIG_BFIN_TRUE_IDE    /* Add CF flash card support */


and use the  connection in this page.




.My CF CARD is SimpleTech SLCF128JIU.  Uboot version is 1.1.6


The erro code seems that there is ECC erro.
