Thread:Talk:R-Car/Boards/M3SK/Booting of kernel stops at 23.047503 mmc0: error -110 whilst initialising MMC card (5)

Hi, I am trying to boot Linux on a Renesas M3SK. I have follow the wiki available on #REDIRECT 1 and I have successfully build a YOCTO image with the version 3.9.0.

Right now I am trying to boot linux from an SD card via serial communication, but kernel boot stops at the following message [ 23.047503] mmc0: error -110 whilst initialising MMC card

Looking through the internet I found out that it is very important to define correctly the number of the device and partition for which the booting will take place. They are two main options mmcblk0p1 and mmcblk1p1. I only made one partition on the SD card and tag it with #1, so the only thing left is to define the number associate to the board. I have tried with both, mmcblk0p1 and mmcblk1p1 and none of them has properly work. Each of them gave me a different error. Please refer to the section Booting logs for a more detailed information.

I have also find a patch available at #REDIRECT 2 but I have not understand what is this patch for and if it is going to help me with my problem.

Could someone give me a solution to this?
