The Sleep Modes documentation notes: Revisions 0 and 1 of the ESP32 only support [ULP coprocessor wakeup] when RTC peripherals are not forced to be powered on (i.e. ESP_PD_DOMAIN_RTC_PERIPH should be set to ESP_PD_OPTION_AUTO). https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/syst...

My watchdog get's triggered

Have a read over the documentation here and you'll see what the problem is:

You could write your own little watchdog using the ULP coprocessor to generate an interrupt if it's not fed for x hours/days/weeks. I suppose that's subject to the same kind of hiccup but what are the odds of it happening twice? (Really, what are the odds of it happening even once?)

Just because there is address space does not mean there is a physical memory element there. I'm not ready to give up on this yet but it looks like I've got some reading to do... Thanks again for your help. ******************************************************************************************* O...

Are there actual functional registers there or do the other registers just have duplicate access at those addresses? To my untrained eye it seems that from the end of the addresses here: https://github.com/espressif/esp-idf/blob/a45e9985344575a80acb1dc9c12e7bec4d8af401/components/soc/esp32/include/...

It occurs to me that it would be possible to use the REG_RD and REG_WR instructions in a ULP program to effectively carve out some address space for custom purposes. I have a ULP program with a lot of boolean-type variables which are very expensive in terms of RTC memory (4 bytes each), where these ...

Incidentally, I just had some PCBs delivered 5 minutes ago where I've done something similar on a little 2-layer board. What I did was to edit a custom WROOM footprint where I've removed the pad entirely (ie. There's soldermask where that pin will be on the WROOM, so it won't be soldered to the boar...

It's safe:

Do you really need 35k for that little json?
Make it much much smaller or allocate dynamically.
