Hi , Expert

as titile description,

follow this thread,

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1097842/tda4vm-how-to-reduce-ddr-speed-to-3733-mts

I try to revert some code to test DDR 3733 MTS

step as below,

The 8.2 SDK has the same commits as 8.0.

cd $PSDKLA_PATH/board-support/u-boot-2021.01+gitAUTOINC+53e79d0e89-g53e79d0e89
git revert 2f21e5b897755334d9a4f2aaacd6945dd2f99cd4
git revert de779d94c7f2b66f0506f44bfc78c2a3e000ecc5
git revert 88f9f21f7ad78a80d1375ee2e7b71ac3ab261b6c
cd ../..
make u-boot
cp board-support/u-boot_build/a72/tispl.bin board-support/u-boot_build/a72/u-boot.img board-support/u-boot_build/r5/tiboot3.bin /media/$user/boot
sync

but I face some problems, as below

Does anyone know how to solve it?

Hi,

This is because 8.2 SDK has some un-committed changes. You can use the below command to commit them before reverting.

Steps:

cd $PSDKLA_PATH/board-support/u-boot-2021.01+gitAUTOINC+53e79d0e89-g53e79d0e89
git add -A && git commit -m "Commit all the changes"
git revert 2f21e5b897755334d9a4f2aaacd6945dd2f99cd4
git revert de779d94c7f2b66f0506f44bfc78c2a3e000ecc5
git revert 88f9f21f7ad78a80d1375ee2e7b71ac3ab261b6c
cd ../..
make u-boot
cp board-support/u-boot_build/a72/tispl.bin board-support/u-boot_build/a72/u-boot.img board-support/u-boot_build/r5/tiboot3.bin /media/$user/boot
sync

The above steps should work for 8.2 SDK.

Keerthy
