I'm currently testing on an OMAP3530 board (tao3530 SOM with custom

and MMC/SDcard detection seemed to work reliably.
But now I noticed that the SanDisk Extreme Pro MicroSDHC 1 (8 GB) is not
detected all the time. It seems that the card detected fails with
timeout on (approx?) each 2nd reboot (via reset button). A quick check
shows that the timeout happens in mmc_send_app_op_cond():
[ 4.901275] mmc0: error -110 whilst initialising SD card
[ 4.939849] mmc1: new SDIO card at address 0001
Is this a known issue? Any ideas on how to fix this?
Just to let you know. I missed to add the "cd-gpios" property to the mmc
DT node. With this addition the detection seems to work reliably.
Sorry for the noise,
Stefan
