We have made it a long way to get our custom AM335x board kernel to boot this far... yea, But now we are stopping at: Waiting for root device /dev/mmcblk0p2
Lots of posts talk about the SD Card Detect line. Our SD Card Socket has the DATA3 and SD line tied together, we have been using this socket for some time now on a previous AM335x board. We have tried several things including using a different ARM MMC0_SDCD pin and tying it low.
Questions:
1. We are using pin C15 (same as BBB) It seems all references to SD Card detect sets pinmux to Mode7 (MMC0_SDCD is Mode5). What should it be set to?
2. What is the kernel looking for on the SD card (file, directory, etc.) when it is waiting at "Waiting for root device /dev/mmcblk0p2" ? We have an Ubuntu ext4 file system on mmcblk0p2.
Thanks again oh TI gurus!
