Fallback image.ub zynq7000

We are using zynq 7000 which loads fsbl/uboot boot.bin from qspi and then image.ub from emmc.

If there is a corrupt image.ub on the emmc it's quite a pain as the emmc can not be programmed over jtag.

I found quite a few resources on how to do failback boot with golden  boot.bin (we implemted that with a golden boot.bin that contains small Linux kernel too)

But I am a bit lost on how to recover if the image.ub is corrupt and can not be loaded and some secondary image.ub should be loaded instead.

Is there a way? Any pointers?

Hi juergen.kratochwill@grapho-metronic.com ,

 

The Fallback mechanism didn't useful here, as the Fallback will only happen at FSBL stage. The device is properly loaded the boot image and it booted up fine till u-boot. As of now the current u-boot doesn't support fallback if the image.ub is corrected.

Best Regards,

Srikanth
