SK-AM62B-P1: eMMC boot

After this I have changed the ./ti-processor-sdk-linux-am62xx-evm-10.01.10.04/board-support/ti-u-boot-*/board/ti/am62x/am62xx.env

I have chnaged the below lines:

-mmcdev=1
-bootpart=1:2

+mmcdev=0
+bootpart=0:1

and then directly set-up environment using ./setup.sh

The file should be called am62x.env. But yes this file in the U-Boot source tree is the correct one to change the permanent environment, as our current SDKs don't support saving the current environment from U-Boot prompt.

I have used directly make u-boot on ./ti-processor-sdk-linux-am62xx-evm-10.01.10.04 terminal.

Yes you need to build U-Boot after your source change. The best is to always build it for both R5 and A53 targets. If you are indeed using the SDK top level Makefile, this is taken care of, as well as the toolchain setup, see https://dev.ti.com/tirex/explore/node?node=A__AeBGnl1mqM7eS2M2n-59Sw__AM62-ACADEMY__uiYMDcq__LATEST    All one would need to do is to issue the `make u-boot` command. I just tried it out to make sure it works and it did. The manual cross-toolchain setup is only needed when building using the Makefile from U-Boot itself.

If this doesn't work for you, first you should double-check all SDK pre-requisites, including but not limited to required Ubuntu 22.04 distribution as well as packages to be installed, see https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/10_01_10_04/exports/docs/devices/AM62X/linux/Overview/Download_and_Install_the_SDK.html#download-install-the-sdk-installer-on-host

Then if this still doesn't work you should provide a log that shows all the relevant details of the commands you are executing and any failure(s).
