[U-Boot-Users] CF card support issue

Hello all,

I support the CF card in u-boot, and met this issue: I used the memory mapped addressing. When set 0xE0(use LBA) to the Drive/Head Register, then read it, it was set 0xE0 correctly. Then I need check the status of the CF card, read the STATUS Register, It always 0x51(ready to accept cmd, card ready, something error). Then I read the Error Register it always 0x04(cmd aborted or invalid cmd). But that configuration was not a cmd.

Why it always got this error? Does someone ever seed this? Some suggests?

Thank you very much!

Terry
