Since publishing the build with the new toolchain, the identifiable crashes have been concentrating within / around the LWIP / Wifi stacks. I have now upgraded to the latest toolchain update (https://github.com/espressif/esp-idf/issues/2892#issuecomment-501106283). As a new Wifi blob still isn't available, I have also disabled CONFIG_WIFI_LWIP_ALLOCATION_FROM_SPIRAM_FIRST to see if that helps. Internal memory use went up a bit, but totally acceptable. I'm going to publish the new build to my "edge" users now. Regards, Michael Am 05.06.19 um 20:57 schrieb Michael Balzer:
It *is* worth trying, Espressif just forgot to mention a necessary build config change.
Details: https://github.com/espressif/esp-idf/issues/2892#issuecomment-499184318
I've created a test branch for this: https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/commits/spi...
I'm now running the new version on both my modules, and they seem to be very stable up to now. Not a single websocket data corruption yet.
I'll publish the build to my "edge" users now.

Not worth trying yet.
It seems the toolchain libstdc++ hasn't been built with workaround, std::string is still broken.

FYI: Espressif have (finally) released a test toolchain for our PSRAM issue:
https://github.com/espressif/esp-idf/issues/2892
Linux <https://dl.espressif.com/dl/xtensa-esp32-elf-linux64-1.22.0-90-g26d9621-5.2.0-psramfix-20190605.tar.gz> Windows <https://dl.espressif.com/dl/xtensa-esp32-elf-win32-1.22.0-90-g26d9621-5.2.0-psramfix-20190605.tar.gz> OSX <https://dl.espressif.com/dl/xtensa-esp32-elf-macos-1.22.0-90-g26d9621-5.2.0-psramfix-20190605.tar.gz>
Apparently, we need to include the following flags:
|CFLAGS+=-mfix-esp32-psram-cache-dupldst CXXFLAGS+=-mfix-esp32-psram-cache-dupldst|
This is a preliminary test fix only, so not for general release, but worth trying.
