Re: esp-wroom-32 multitask

Can you also post the bits above the error message? Your single line isn't really informative.

Re: ESP32 PSRAM support

If any, post 2.1.

Re: Crash in timer interrupt

What does micros() do? Also, how do you set up the interrupt?

Re: how to reset the ccount register?

To add to what's said above: If you do manage to write there, be aware that it probably breaks FreeRTOS: we use the ccompare functionality (which depends on ccount monotonically increasing) for scheduler timing, so resetting ccount will most likely break pre-emptive scheduling.

Re: Interrupts issue

What do you mean, 'crash with code 261'? Do you get a guru meditation error? Can you post your specific code here?

Re: Minimum supply voltage?

FWIW, the V_BAT spec is missing in the current data sheet, so I think it may have been a holdover from the ESP31 days. As far as I know, 2.3V is the actual minimum, although I wouldn't be surprised if there's a 0.3V safety margin and the ESP32 will work on 2.0V in normal environmental circumstances ...

Re: Wifi Disconnect Loop

FWIW, we're aware of this bug and we're trying hard to get this fixed before the 2.1 release.

Re: Interruptions issue

Yes. With a low _level_ interrupt, the interrupt will keep on triggering over and over again while the button is pressed, causing the CPU to execute nothing else anymore and the WDT rightfully kicking in. Neg edge probably does what you want here.

Re: Power Consumption in BlueTooth mode.Hi

Yes, although I can imagine its location is slightly less findable. Easiest way is to disable 'Component Config -> esp32-specific -> Reserve memory for two cores'; this will also disable FreeRTOS multicore support and should keep the 2nd cpu clock gated.
