Linux: A error about the MLO on AM3352 board

Other Parts Discussed in Thread: AM3352

Tool/software: Linux

Hi,My board is AM3352 board,my SDK version is v03.02,when I use the prebuilt-images/u-boot-spl.bin-am335x-evm or MLO-am335x-evm to run on my board,the serial port terminal can't see any message print out,only 'CCCC'!

But if I use the v01.00,I can see the message like this 'U-Boot SPL 2014.07-gfb6ab76 (Jul 06 2015 - 16:00:22)'!

Why ?

Hi,

Is this a custom board?

The 'CCCCC" on your console means that your board is trying to boot out of uart. When you create your bootable sdcard you need to copy MLO & u-boot.img files on the boot partition. Those correspond to:
prebuilt-images/MLO-am335x-evm ====> copy to boot partition & rename to MLO
prebuilt-images/u-boot-am335x-evm.img ====> copy to boot partition & rename to u-boot.img

Best Regards,
Yordan

Hi,Thanks for your answer.I have copied the MLO and u-boot.img to my SD Card,If I use the SDK of v01.00.xx,the console print is ok,I can see like this 'U-Boot SPL 2014.07-gfb6ab76 (Jul 06 2015 - 16:00:22)',but if I use the latest version(v03.02),nothing can be printed.After five ‘C’ it stoped!
