[Ovmsdev] PSRAM fix in esp-idf release v3.3

[Michael Balzer]

Mark,

it seems the fix has finally arrived in the official release 3.3 branch:

https://github.com/espressif/esp-idf/commit/f4333c8e3a554e8bb4210d825cbdf4bcaa1fc1b8

Btw:

I guess that means from some manufacturing point on we should provide
two builds, one for the older hardware and one for the modules with v3

Regards,
Michael
