Hi,
We are using a custom board based on am5708 and using ti-processor-sdk-linux-am57xx-hs-evm-08_02_01_00.
We have generated MLO, u-boot.img, kernel and rootfs using SDK.
We flash the wic image generated by SDK onto the sd card and the board is booting perfectly fine. The following is the partition scheme:
Disk /dev/mmcblk1: 30 GB, 31914983424 bytes, 62333952 sectors 486984 cylinders, 4 heads, 32 sectors/track Units: sectors of 1 * 512 = 512 bytes Device Boot StartCHS EndCHS StartLBA EndLBA Sectors Size Id Type /dev/mmcblk1p1 * 384,0,1 639,3,32 49152 81919 32768 16.0M c Win95 FAT32 (LBA) /dev/mmcblk1p2 640,0,1 1023,3,32 81920 4095999 4014080 1960M 83 Linux /dev/mmcblk1p3 1023,3,32 1023,3,32 4096000 8110079 4014080 1960M 83 Linux /dev/mmcblk1p4 1023,3,32 1023,3,32 8110080 8372223 262144 128M 83 Linux
We copy the same wic image on the SD card and flash (using "dd" command) it onto the emmc. It also has the similar partition scheme.
Disk /dev/mmcblk0: 7456 MB, 7818182656 bytes, 15269888 sectors 119296 cylinders, 4 heads, 32 sectors/track Units: sectors of 1 * 512 = 512 bytes Device Boot StartCHS EndCHS StartLBA EndLBA Sectors Size Id Type /dev/mmcblk0p1 * 384,0,1 639,3,32 49152 81919 32768 16.0M c Win95 FAT32 (LBA) /dev/mmcblk0p2 640,0,1 1023,3,32 81920 4095999 4014080 1960M 83 Linux /dev/mmcblk0p3 1023,3,32 1023,3,32 4096000 8110079 4014080 1960M 83 Linux /dev/mmcblk0p4 1023,3,32 1023,3,32 8110080 8372223 262144 128M 83 Linux
But u-boot wont come up with eMMC. It stops at SPL and here is the log:

I tried to follow this link:
but ended up getting these security events:

Please help me in getting this solved.
Thank you
