Part Number: AM6442

In the SDK8.6 UBoot still save env to FAT with booting from eMMC, it is reported in below post of after SDK7.3.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1014005/processor-sdk-am64x-u-boot-changes-to-save-environment-values-to-root-fs-in-emmc/

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1031148/faq-tda4vm-u-boot-changes-in-sdk-8-0-vs-7-3/3812260#3812260

No plan to fix it? or don't think it is a issue?

    Hi,

    I see it has not been merged in u-boot, I can submit the patch, however, it will not be available for 08.06 SDK.

    Hi Tony,

    The patch will not go into 08.06 SDK or 09.00 SDK, the releases are out and will not be updated. The patch has already been shared in the link you provided. I can submit a patch but it will be merged until 09.01 release.

    Hi Tony,

    Yes that is the patch that needs to be applied to u-boot source.
