Problems booting i.MX6SL EVK from SD1

[rathben]

I'm trying to boot using the core-image-minimal-imx6slevk.sdcard image, built using yocto and the Freescale 3.10.17_beta release. This image boots fine from SD2, but I get the following when booting from SD1:

Any ideas? Has anyone successfully booted from SD1 on the i.MX6SL EVK?

Yes, board/freescale/mx6slevk/mx6slevk.c is where the pins are configured in U-boot source code.

Currently only SD2 is configured there. if you want to use SD1 in U-boot, then you need to add code that configures the SD1 pins and register the SD1 port as well.

Note: I will be out until Wednesday, so probably not be able to respond here.

Ben,

Looking at board/freescale/mx6slevk/mx6slevk.c we can see that only the usdhc2_pads are defined.

You need to extend the pin settings for the SD1 as well.

I'm not sure I understand. Is this a u-boot change?
