PROCESSOR-SDK-AM62A: How to create or flash partition table into new eMMC user partition using DFU flashing

Gnanachandran Dhanapal

Hello There,

For the AM62A EVM, A partition table can be created using fdisk by booting the system through an SD card. However, the partition table (in gpt bin) couldn't be flashed using the DFU tool. so, please share the procedure to create or flash a partition table in the eMMC user partition without using an SD card.

Cheers

Hi,

If you are creating one partition in UDA (User Data Area) partition for the rootfs, then please use the following doc:

https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/07_03_00_05/exports/docs/linux/Foundational_Components/U-Boot/UG-Memory.html#partitioning-emmc-from-u-boot

However, please know that uuidgen program is not enabled by default in our SDK, but you can still create a partition using the gpt write command in u-boot.

Please read the following doc: https://github.com/u-boot/u-boot/blob/master/doc/README.gpt to get a good understanding of gpt command in u-boot.
