I am able to create a device with Flash Encryption and a device with Secure Boot, but I have been unable to create them together.
I have read all the documents I can get my hands on a dozen times and I just don't see the clear way forward on this.
Any suggestions on how to get both working together?
Is there an order of operations that I need to know?
I'm working on an s3 with V2.
Thanks for the help out there.... Keith

I must be close to the solution, but the final details are pretty challenging. If someone knows the path and wants to consult with me on it -- contact me. I'll throw some resources at it. Thanks.

I found a big problem in my build.... I'm running an esp32s3 N16R8 on the 4.4.1 release. I'm also using Octal PSRAM. There is a bug that doesn't allow Flash Encryption to work. Installing patch now to correct for that bug. Here is a link to that report with a link to the patch at the bottom of that page:

OK -- I figured it all out. I am successful at combining Flash Encryption with Secure Boot V2 on the Esp32s3 N16R8 in the IDF 4.4.1.
In all, I will have burned through 5 DevKitC clones.
This only took me two weeks....

@KeythInAsia: Excellent, can we get you to do a writeup? I'm sure it would be interesting for many other people to read.
