I'm currently using ltib with the patch linux-220.127.116.11-imx_11.09.01_201112 applied, as per MX53_LINUX_BSP_201112_Patch_release.pdf document. Maybe I'm doing something really wrong, but I can't have usb running, and dmesg tells me:
[ 2.765806] Warning: unable to open an initial console.

After that, I have the prompt but the usb keyboard is not running.
I'm seeing that the first usb error is printed before the initrd is loaded, too.
The board runs fine with the original mmc ( the one with Ubuntu factory loaded ).
Additionally, on the START Board ( the Dialog based one ) the same kernel runs fine, and usb is ok.
I have the same results using a kernel built outside ltib, with all the patches applied.
I'm stuck on this from yesterday, any guy has some hints, or a running .config file if this is the case?
Thank you in advance
