Everyone,

the announced bug fix for the regression in toolchain 1.22.0-96-g2852398 has been released for esp-idf v3.3.

I've merged the latest updates to esp-idf release 3.3.4 into our fork and added the new options to our default build configuration. This includes some additional PSRAM related fixes.

The toolchain download links in the docs have not yet been updated. Use these links to download the new toolchain:

See https://github.com/espressif/esp-idf/commit/81da2bae2aa3e15a1793d40bb9648620f8cd2555 for other architectures.

Simply replace your existing toolchain installation by unpacking the archive. Test your toolchain installation by checking xtensa-esp32-elf-gcc --version.

To update your esp-idf clone:

cd $IDF_PATH
git pull
git submodule update --recursive

Replace your sdkconfig by the default one or set all new config options to their defaults. I recommend doing a full rebuild of the OVMS firmware (i.e. make clean ; make). You should then get firmware version 3.2.015-150-gf6121ddd/factory/edge (build idf v3.3.4-845-gd59ed8bba Nov 8 2020 11:50:31) or higher.

Regards,
Michael

But according to the latest comment to the PSRAM issue
(https://github.com/espressif/esp-idf/issues/2892#issuecomment-667099130)
the fix in the official release had a regression. In some cases, the bug
will occur again. The report issue #5423 had the effect of this freezing
the LwIP task, which would create the WDT / event issue for us as well.
I'd rather apply the coming toolchain fix release first.

I'll keep you informed about the toolchain progress.
