TDA4VM: Linux OTA A/B upgrade solution for whole chip

Shine

Part Number: TDA4VM

Hello Champs,

Customer wanted to know if TI has Linux OTA A/B upgrade solution for whole chip.

He has referenced below thread, but it is only for MCU domain, he wanted to the OTA for whole chip.
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1043419/tda4vm-q1-firmware-of-tda4vm

If it is not available, does TI recommend open source OTA solution？

Thanks
Regards

Shine,

Can you elaborate more? What will be stored on A/B partitions? Is this eMMC that you want to write to?

Best Regards,

Hi Keerthy,

Thanks for your great support.

Yes, customer wanted to do OTA upgrade on emmc. Uboot, kernel and rootfs need to do A/B partitions upgrade.

Thanks

Shine,

For J721e we have 2 boot partitions. So basically we have A/B partition for bootloaders.

By default boot0 partition is used to boot from eMMC. To switch to boot1 partition we can use U-Boot environment variables & also to switch back and forth between boot0/1.

Here is the FAQ: https://e2e.ti.com/support/processors/f/791/t/1084875

For rootfs there is no ready solution. You will have to manually create 2 rootfs partitions & store kernel images.
You can switch between the 2 rootfs partitions using U-Boot bootargs.
