Re: Failed to communicate with the flash chip
Check 2 and 12. Both should be low. You can try removing everything connected to these pins externally to allow the internal pulldowns to do this automatically.

Re: ESP32-C6 Low Power hanging device?
You only set esp_sleep_enable_timer_wakeup once. After the first sleep+wakeup, there is no wakeup source configured so it's expected that it remains in light sleep forever.
Try moving esp_sleep_enable_timer_wakeup to the line before esp_light_sleep_start.

Re: WiFi station no longer finds APs after 5 minutes of scanning
You want to rule out a memory leak exhausting heap memory, not your task's stack.
Log these after each scan: esp_get_free_heap_size(), esp_get_minimum_free_heap_size()
Log these after each scan: esp_get_free_heap_size(), esp_get_minimum_free_heap_size()

Also esp_now_send return value only indicates that the packet was internally queued successfully. You need to use the send callback to determine the outcome of sending it.

Re: freertos task does not cleanup c++ class objects on vTaskDelete
vTaskDelete doesn't return so obj never goes out of scope so obj's destructor never runs. This is expected. C++ has no way of "knowing" what vTaskDelete(NULL) does, it can't be cleaning up anything upon arbitrary function calls that it expects to return from. A separate function or your commented br...

Re: ESP32-S2: need to adjust Brown Out Level at runtime
However, if I programmatically set the brown-out detector threshold to 3.19v right before shutting off the boost converter (remember, the ultracap is 3.0v max), the ESP32-S2 is guaranteed to be held in brown-out reset until VDD reaches 3.30v. What is guaranteeing this? I would expect an immediate b...

ESP32 USB DFU Bootloader
https://github.com/boarchuz/bo_dfu Bitbanged USB Low Speed and DFU for the ESP32 2nd-stage bootloader. It works surprisingly well, give it a try! It's surreal plugging my ESP32 into my phone and updating it in a web browser (when WebUSB decides to work, at least). Some ideas: enable OTA updates with...

Will overwrite. Only one is supported.
