AM5728: AM5728 - eMMC loading without SD-Card

Hello Rohit,

There are two questions here:

We would like to know if there are alternative methods to program/load software directly into eMMC on a bare board, without relying on any additional memory like SD card.

There is a couple of methods:

• DFU - see https://software-dl.ti.com/processor-sdk-linux/esd/AM57X/11_01_02_01/exports/docs/linux/Foundational_Components/U-Boot/UG-Memory-OMAP.html#sd-emmc-and-usb
• Uart - See https://e2e.ti.com/support/processors-group/processors/f/processors-forum/694691/ccs-am5728-emmc-flashing-via-jtag#:~:text=Part%20Number:%20AM5728,%2Dboot%2C%20and%20through%20UART0.
• Jtag

Additionally, we would like to know, is there any authentication or secure mechanism to ensure that only authorized software can be loaded onto eMMC?

This question is essentially a security question and you would need to switch over to Security enforced devices which are not directly supported one AM572x. Our recommendation is to switch over to AM574x secure devices. Please consult with your local FAE for more information.

If any further questions, please submit another thread. 

Lets dedicate this thread to the original title.
