Subject: [U-Boot-Users] CF card support issue
Date: Mon, 10 Apr 2006 10:21:25 +0800 [thread overview]
Message-ID: <1144635685.3121.17.camel@Terry> (raw)
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
