Hi,

I am trying Jetpack 4.4 and all of source is the default one.
Found boot loader(mb2) cannot be upgraded successfully if ever save environment in u-boot(by command saveenv).

Seems secondary_gpt(4193792 ~ 4194304) offset is overwritten by uboot env(4186112 ~ 4194300) in mmcblk0boot0.

Please help on this.

Thanks

Hi,

It sounds an issue. Could you share the step (what did you save in uboot?) to reproduce this issue?

4

do not save anything. just type “saveenv” in uboot cli.

Hi,

We have two patches for you to try.

1st patch is in uboot.
febfeaa.diff.zip (1.3 KB)

2nd patch is in the partition layout change that you need to apply to the xml file under Linux_for_Tegra
25668e2.diff.zip (1.7 KB) .

Is there a chance to adapt this for L4T R32.3.1?
I tried to adapt it but at the stage of flashing the device i always run into the following error:

Can you tell with which release this will officially be fixed?

Hi,

Sorry that we won’t adapt any fix back to old release.

Can you tell with which release this will officially be fixed?

Next rel-32 branch release will have it.
