ESP32P4 support?

[Maldus512]

Answers checklist.

• I have read the Rainmaker documentation and the issue is not addressed there.
• I have updated my IDF branch (release/vX.Y) to the latest version and checked that the issue is present there. This is not applicable if you are using Rainmaker with Arduino.
• I have searched the Rainmaker forum and issue tracker for a similar issue and not found a similar issue.

General issue report

Hello everyone. I am trying to build the switch example for an ESP32P4 board, but compilation fails with a weird error:

I am using ESP-IDF v5.5 (release branch, up to date).

I noticed the ESP32P4 module isn't listed as supported in the README. Is it something foreseen to be added at some point? Is it actually missing, or am I not seeing the real source of the problem?

[vikramdattu]

Yes, P4 is on cards and will be added. BTW, it is already added as a part of the new camera devices we have introduced.

[Maldus512]

So is the build error I'm encountering expected?
Is there a rough timeline on P4 support? I need to decide if I can start developing a project with it or whether I should fallback to one of the supported SoCs.
