I have a IMX53 board, with a bootloader, kernel etc that can start form SDCARD.
Now I would like to use MFGTOOL, but trying the u-boot/kernel inside the pacakges (22.214.171.124), i get some error, and on my UART1 don't see anything.
I I would simply load u-boot on ram and execute it, this code is right?
<LIST name="NAND2" desc="NAND: U-Boot, Linux, ROOTFS">
<CMD type="boot" body="BootStrap" file ="u-boot-noh.bin" >Read from DDR script from U-Boot to init DDR Memory.</CMD>
<CMD type="jump" > Jumping to OS image. </CMD>
Tipically I write on SD card the u-boot.bin with:
dd if=u-boot.bin of=/dev/SDCARDDEV bs=512 skip=2 seek=2
now for generating the u-boot-noh.bin (used in MFGTOOL), I do:
dd if=u-boot.bin of=u-boot-noh.bin bs=512 skip=2
If i use it on SDCARD I see the console on UART1, using in MFGTOOL I don't see anything on UART1.
What I need to do for starting a simple u-boot.bin from USB?
