2011-07-15 19:06:22 ---Hi Chris,
first of all thanks for your help.I'm finish with some of your tips:
The tip of comment #4 doesen't work. I've got the error message that the config wasn't able to load. Also the cardreader doesn't work.
The other thing I've done was the bisection thing. The result is this commit:
a3c7778f8153b9e4eceea6738973280b9e63c618is the first bad commit commita3c7778f8153b9e4eceea6738973280b9e63c618Author: Andrei Warkentin <[email protected]> Date: Mon Apr 11 16:13:42 2011 -0500mmc: sdhci: R1B command handling +
MMC_CAP_ERASE.ERASE command needs R1B response, so fix R1B-type command handling for SDHCI controller. For non-DAT commands using a busy response, the
cmd->cmd_timeout_ms(in ms) field is used for timeout calculations.
