Thanks ESP-Marius. Changing ESP_LOGI to ESP_EARLY_LOGI in lib_printf did indeed stop the aborts. But there seems to be some other problem with the wifi module. In an earlier version of 4.3 it worked fine, but now it takes 10 seconds after boot before the wifi manages to start up then it looks like i...

And where do I find these 2 files, since those paths don't refer to anything on my Windows machine. 0x4010bd0a: _vfprintf_r at /builds/idf/crosstool-NG/.build/HOST-x86_64-w64-mingw32/xtensa-esp32s2-elf/src/newlib/newlib/libc/stdio/vfprintf.c:853 (discriminator 2) 0x4010ed69: vprintf at /builds/idf/c...

On an ESP32-S2 using ESP-IDF v4.3-beta1-25-g603db1828 I'm getting a deterministic abort about 1400ms after boot. The backtrace doesn't reference any of my code. abort() was called at PC 0x40026786 on core 0 0x40026786: lock_acquire_generic at E:/Dev/Espressif/esp-idf/components/newlib/locks.c:138 Ba...

Anyone?

I'm getting a LoadProhibited out of a library that I have been happily using for several years. Guru Meditation Error: Core 0 panic'ed (LoadProhibited). Exception was unhandled. Core 0 register dump: PC : 0x400dc335 PS : 0x00060e30 A0 : 0x800e620c A1 : 0x3ffda3e0 0x400dc335: ArduinoJson::Internals::...

OK, much thanks to Angus for help on this one.

Turns out it was a conflict between flash and PSRAM brought on by our erroneous use of GPIO26 on the ESP32S2 Wrover.

Angus, none of those Saved PC addresses look valid: E:\Source\wylas\beamatouch>xtensa-esp32s2-elf-addr2line -pfiaC -e build/beamatouch.elf 0x40334a6f 0x40334a6f: ?? ??:0 E:\Source\wylas\beamatouch>xtensa-esp32s2-elf-addr2line -pfiaC -e build/beamatouch.elf 0x40334a71 0x40334a71: ?? ??:0 E:\Source\wy...

@ESP_Angus we realise this might be intractable without the source code.
How can we share that with you privately?

To put this in context. This code works // All My setup code is above here. ESP_LOGI(TAG, "Finished setup"); // NB this line was added just to stop the app from aborting during startup. It is a hack. // See https://www.esp32.com/viewtopic.php?f=2&t=18842 ESP_LOGI(TAG, "Finished setup2"); // while (t...

Hi Angus. Some answers. Yes the apps is definitely running for 1.2 seconds. There is app log showing. Yes, the log output indicates that it is past the bootloader and into the app. I assumed it had to be to do with the bootloader because the address given only appears to be valid for the bootloader,...
