AM5728: SD card boot fails

user402416

Part Number: AM5728

I am using processor_sdk_rtos_am57xx_4_02_00_09, and boot from SD.

I used pdk_am57xx_1_0_9\packages\ti\boot\sbl\binary\evmAM572x\mmcsd\bin\MLO, but there is noting printed in uart.

When I use the MLO in processor_sdk_rtos_am57xx_3_01_00_06\prebuilt-sdcards\evmAM572x\sd_card_files, uart outputs some messages.

I compile the sbl of processor_sdk_rtos_am57xx_3_01_00_06 to MLO, the uart output noting. Is processor_sdk_rtos_am57xx_3_01_00_06\prebuilt-sdcards\evmAM572x\sd_card_files\MLO created from the source code of these version? How to create the MLO file from .out file?

Thanks a lot.

Details of converting out file to MLO and creating app file from .out is provided in Bootloader section of the software defined guide:

Can I ask, why you are using older baseline of Processor SDK RTOS? Did you make any modification to the SBL source or just re-built the binary?

I tested the MLO and app from that version of the release and have no issues. Can you please check the HW setup (boot switches, UART connection, power supply). How did you format the SD card. Ensure that you have used the steps described here:

I have found the reason that our board doesn't have EEPROM, so the MLO will stop at the reading function.

Thanks a lot!
