If pin 32 is configured as a RTC GPIO then it should be unaffected by a software restart so that's the expected behaviour. If it's configured as a digital GPIO then it should be reset back to default.

RTC WDT will reset everything. It's functionally equivalent to toggling the enable pin.

Are you missing a pullup on EN?
Also you need separate 5.1k resistors for each USB CC pin. Raspberry Pi had well-publicised problems sharing the resistor like that.

can I trigger the watchdog manually? The linked IDF snippet will do this - set the timeout to 0 to reset immediately. Would a full restart like the one you mention clear the RTC_NO_INIT memory? It shouldn't ever be cleared. I'm guessing memory isn't powered down during a RTCWDT reset so I would exp...

A software restart (including panic, abort, etc) doesn't reset the whole system. Only power on, RTC WDT, and brownout will do that. You can do a 'full' reset in software by using the RTC WDT. This is a good start: https://github.com/espressif/esp-idf/blob/70109e23939e13229f36d9e8dca9797abfeeb8aa/com...

const size_t bootcss_size = ((bootstrap_css_end-1) - bootstrap_css_start) httpd_resp_set_hdr(req, "Location", "/bootstrap_min_css"); Why (bootstrap_css_end-1)? EMBED_TXTFILES will null-terminate, but EMBED_FILES should embed the file as-is. What's the intention of the Location header? At best the b...

if (WakkerMaakReden != ESP_SLEEP_WAKEUP_ULP){ init_ulp_program(); } start_ulp_program(); When woken by the push button, you're reinitialising everything related to the ULP while it is still enabled or even active. In my experience, overwriting its program memory while running can cause the ULP to l...

I suspect mangling is ruining your day, try: You will likely need to add to the default one as well, and you might need the weak attribute in its definition.

Try disabling data so that WiFi is the only network connection.

Logs could be helpful.

Also, having just seen your GitHub issue with includes ordering, you might be interested in copying/referencing my config here which should resolve that: https://github.com/boarchuz/espidf-vscode-ccpp/blob/master/c_cpp_properties.json (make sure to select "ESP-IDF [Xtensa | esp-2021r2-patch3-8.4.0]"...

deleting compileCommands seems to have fixed it. "compileCommands": "/Volumes/User/MBP-Google-Drive/jamcorder/firmware/jamcorder-firmware/jamcorder_app/build/bootloader/compile_commands.json" You will get better help with compileCommands, you just have the wrong path there (that's the bootloader pa...
