Hi, I am using P1020 rdb for my project. I want to boot my RAM based u-boot image from sd card.
I have followed this freescale guide to prepare my sdcard :
Getting Started Guide for P1020/P1011
As per as the guide, the sd card preparation for the RAM-based u-boot is to be done in the board itself. So, I first load the kernel image from NOR. Then I copied the boot_format, config_file and u-boot image to any directory in board.
I run this command : boot_format config_file u-boot.bin -sd /dev/mmcblk0
After which, I got the following :
It is a big endian machine.

To boot my u-boot from sd card, i change the boot config switches to 001001, and then power ON the board. I am not able to load my u-boot image.
