Other Parts Discussed in Thread: PMP, DRA752
Tool/software: Linux
I have a AM5728 custom board.
I split the sd card's partition into two partitions via create-sdcard.sh provided by sdk (8GB capacity).
The following dt and pinmux have been modified for custom boards.
software-dl.ti.com/.../Foundational_Components_U-Boot.html
I built u-boot and the kernel as shown in the above guide and copied the image to the sd card.
But I can not move from u-boot to the kernel.
Could you tell me why?

mmc - MMC sub system
Usage:
mmc info - display info of the current MMC device
mmc read addr blk# cnt
mmc write addr blk# cnt
mmc erase blk# cnt
mmc rescan
mmc part - lists available partition on current mmc device
mmc dev [dev] [part] - show or set current mmc device [partition]
mmc list - lists available devices
mmc hwpartition [args...] - does hardware partitioning
arguments (sizes in 512-byte blocks):
[user [enh start cnt] [wrrel {on|off}]] - sets user data area attributes
[gp1|gp2|gp3|gp4 cnt [enh] [wrrel {on|off}]] - general purpose partition
[check|set|complete] - mode, complete set partitioning completed
WARNING: Partitioning is a write-once setting once it is set to complete.
Power cycling is required to initialize partitions after set to complete.
mmc bootbus dev boot_bus_width reset_boot_bus_width boot_mode
- Set the BOOT_BUS_WIDTH field of the specified device
mmc bootpart-resize <dev> <boot part size MB> <RPMB part size MB>
- Change sizes of boot and RPMB partitions of specified device
mmc partconf dev [boot_ack boot_partition partition_access]
- Show or change the bits of the PARTITION_CONFIG field of the specified device
mmc rst-function dev value
- Change the RST_n_FUNCTION field of the specified device
