Other Parts Discussed in Thread: AM3359
Tool/software: Linux
We are using AM3359 processor in our custom board and SDK version is ti-processor-sdk-linux-am335x-evm-05.00.00.15. We want to boot our board using eMMC and not from SD card.
In our board SD Card is connected to MMC0 and eMMC is connected to MMC1.
When we are setting our sysboot configuration SYSBOOT[4:0] as 10111b, (Boot sequence - MMC0, SPI0, UART0, USB0), we are able to boot from SD Card and we are getting no error when we access eMMC using fdisk after booting.
When we are setting our sysboot configuration SYSBOOT[4:0] as 11100b, (Boot sequence - MMC1, MMC0, UART0, USB0), we are not able to boot from eMMC but it boots from SD card afterwards. And when we access eMMC after booting using fdisk we are getting following error.

In both the cases, we are unable to boot from eMMC from uboot using mmcboot command.
Kindly help us to resolve this issue as soon as possible as we have severe time restriction.
Thank you.
