RTOS/BEAGLEBOARD-X15: Board diagnostics issue

Part Number: BEAGLEBOARD-X15

Tool/software: TI-RTOS

Hi ,

I tried to run the sdk rtos board diagnostics using sd card, but it didn't work. I did as the sdk developer's guide say and i saw the video, too. First I compiled the diagnostic application in the sdk and i didn't change the source code at all. Then I copyed all the files in the sdk\packages\ti\board\bin\evmAM572x\sd and the MLO file in the sdk\packages\ti\boot\sbl\binary\evmAM572x\mmcsd\bin to the SD card.Then I inserted the SD card to the Beagleboard_x15 board and poweron the board. But the uart console showed nothing, and the active led on the board just lighted up only a short time then down. 

I tried both sdk_rtos_am57xx_4_03_00_05 and sdk_rtos_am57xx_5_00_00_15, and the results were the same.I think it may has something wrong with the MLO file, because when I powered on the board, the uart didn't output anything. So it means that the SBL doesn't work at all.

Can the MLO and diag example in the sdk work on BeagleBoard_x15? 

Thanks for your reply.
