IDF 5.1.1 supporting many variants of ESP-WROVER-B

Espressif Support:

We've got 5+ years of product in the field using ESP-WROVER-B. In that time, there have been changes to the RAM and/or Flash chips. I don't think there's been ESP32 chip revision change, but perhaps?

Anyways, the issue is we are getting some reports of certain units in the field bootlooping after update to the IDF5-based firmware. We are actively investigating but it involves shipping units back/forth to customers and opening them to attach debuggers... so I'm reaching out to see if there's any guidance on how to maintain compatibility here?

I will update this topic with some details this week as we gather info.

Thanks, Chris from Bond.
