Recovery and OTA Query

[jaivishnu.m]

Hi devs,

we are currently using the xavier nx emmc variant with nvme 2 TB on Jetpack 5.1.4. There are few query i would like to have your inputs here on my understanding,

1. Is it possible to partition the 2 TB boot medium with AB scheme in which A should have 1.8 TB and B should have 100 GB

2. if yes, can i do OTA update with 1.8 TB for A partition and 100 GB for B partition? or OTA is independent of partition size?

3. In case if i dont use AB scheme is there any limitaitions on OTA part that i should be aware of?

Regards,
Jai

Hi David,

Thanks for the inputs.

However, what i am trying to achieve here is not two equal halves for the APP and APP_B. I am trying to achieve custom size (1800GB) for APP and other custom size (100GB) for APP_b.

Regards,
Jai

Hi jaivishnu.m,

Got it.
Please refer to the FAQ section.
It works in AGX Orin, and you could apply same logic in your Xavier NX.

Thanks
