I'm currently testing on an OMAP3530 board (tao3530 SOM with custom baseboard) with v3.14. I applied all the OMAP/pbias patch from Balaji 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.
