TDA4VH-Q1: GPT Partition in SD Card

Hi TI Experts,

Customer is working on TDA4VH SDK9.0.

They want to use GPT partition in SD card. After some studying on our SDK guide, we could only find the description below for using GPT partition with EMMC.

https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/08_06_00_42/exports/docs/linux/Foundational_Components/U-Boot/UG-Memory.html#partitioning-emmc-from-u-boot

However, we could not find the guide to use GPT partition with SD card.

Seeing from our SD card boot guide, there are two modes of SD card boot. One is using filesystem to load the programs, the other is to use raw mode to load.

For using the filesystem, by default the MSDOS is working as expected, but when we use GPT, all the programs are still put in the first fat partition, causing the system cannot boot up.

For using the raw mode, we could not find the description in our guide about the location of loading the program.

May I know if there is feasibility to use GPT partition with SD card, if so could we have some guide to follow please?

Thanks a lot!

Kevin
