That sounds perfect, but I can't see that in the ESP-IDF. I can see it in this tutorial, looks like it's installed when adding boards on the Arduino platform? https://randomnerdtutorials.com/esp32-save-data-permanently-preferences/ I'm using ESP-IDF V4.4, do you know of any examples that are would w...

Hi all, I'm having some trouble implementing a way to save some settings that I want to be configurable. These will rarely be changed (if ever), but having the option is very valuable. It looks like blob storage is the most appropriate, but I haven't been able to find or adopt an example that works ...

Hi all, I have possibly an unusual request. I would like to intentionally crash the ESP32-S2 co-processor so I can test some recovery code and a few sequences I have around this. Previously I've been able to crash the co-processor easily and reliably by using while(1) with nothing in it or dividing ...

Ok, thank you for responding.

I'll submit an issue on github and post back here when it gets resolved to help with anyone in the future.

Cheers,

Hi all, Just bumping this and hoping to ask an open question to whoever is looking through my posts. I have posted a few questions relating to the ESP32-S2 co-processor and related items, but I don't appear to be getting answers. Am I not giving enough detail, or is my posting style confusing, or is...

Hi all, Running similar code to this example and using the functions: ulp_riscv_wakeup_main_processor(); ulp_riscv_shutdown(); I would have expected the shutdown function to do exactly as described and the co-processor more into HALT state or just off altogether and not run until initiated in the ma...

It's likely similar to the issue I faced with interrupts for sleep modes.

What GPIO's are you using? If it's GPIO18+ this may be the issue.

Have a look around what I did here, it might help.

Hi all, This issue has been resolved. This issue is related to the ESP32-S2 board and its compatibility with current esp-idf (I'm using V4.4). To get this working on an ESP32-S2, you need to modify the file sleep_modes.c as follows: typedef struct { esp_sleep_pd_option_t pd_options[ESP_PD_DOMAIN_MAX...

Hi all, I am still having trouble with this. I have replicated this issue here: https://github.com/DylanGWork/esp32s2ulp-interrupt This shows the ULP co-processor either having an interrupt, or working code in the ULP co-processor, but not both at the same time. It seems as though I can't have an in...

Hi all, I have been attempting to set up a button press interrupt from the main CPU (easily done) while having the ULP still running. I have run into an unexpected issue with using the function: esp_sleep_enable_ext0_wakeup(Button, 0); The ULP program is: [Codebox=c file=Untitled.c] int main (void) ...
