AM625: How to check the boot0 and boot1 partitions?

Shine said:

During emmc booting, we an use ls mmc 0:1 command to check rootfs partition and files. How to check the boot0 and boot1 partitions?

The SDK User's Guide has some explanation on this, see https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_00_00_03/exports/docs/linux/Foundational_Components/U-Boot/UG-Memory.html#booting-tiboot3-bin-tispl-bin-and-u-boot-img-from-emmc-boot-partition-for-k3-class-of-socs

Basically, you can switch to the boot0 partition using the `mmc dev 0 1` command, and then you can access the data (in raw format, because there's no filesystem!) using the usual `mmc read` and `mmc write commands. Similarly, for accessing the boot1 partition, first switch to that partition using  `mmc dev 0 2`, before doing any raw access.

Hi Shine,

The last zero in the `mmc dev 0 0` command used as the parameter for the partition refers to the user data partition/area (also known as UDA). If you don't specify this last partition parameter it actually defaults to `0` so usually it is not specified at all in this case.
