Redundant FIP/u-boot in stm32mp157

Hi,

Our goal is to make FIP redundant. We are using RAUC mechanism to update TF-A and FIP. Manually, using `rauc install` CLI tool, I am able to update both TF-A and FIP. If I reboot the system, new TF-A and new FIP is loaded.

 

However, when I created a rauc bundle for either fip or tfa that has corrupted fip and tfa binaries and updated it in the HW, system crashed on reboot. It didn't go on to boot from other tfa or fip partition.

If there is any defined mechanism to make FIP redundant in ST infrastructure?

 

Thanks

~Umar
