Hi,
We developed a custom board with AM5718 processor and using ti-processor-sdk-linux-am57xx-evm-05.02.00.10. I the process of flashing eMMC we have made it into 2 partitions and loaded customized kernal and dtb file, but when we tried to boot from eMMC it has entered into u-boot prompt without any interruption.
And in the below mentioned log we have also added print env for the eMMC, could you suggest us whether we have to bother about any parameters regarding eMMC printenv or is there any problem.
