Guru Meditation Error: Core 0 panic'ed (StoreProhibited)
ernitron opened this issue · 4 comments
I followed to the letter your instructions for recompiling micropython. I even tried this last update using the USER_C_MODULES. Compilation was OK. Used esp-idf.py 4.2. But I get Guru Meditation Error: Core 0 panic'ed (StoreProhibited). Which seems different (LoadStoreAlignment) you mentioned. I tried different, devices, power configurations, ways to upload firmware all with same results.
Besides, I get exactly the same error when trying your latest firmware.bin so I suspect something different but I have no clue.
Any hint will be appreciated as I am really stuck.
This is the output from serial (looks like panic message from ESP32 FreeRTOS but I cannot decode what it means):

I just got back to the original main.c without the fix suggested in your point 2 and it works now, meaning that the firmware.bin starts gracefully without exception to memory fault. Well, I am struggling now with camera.init(0) as I guess I have to figure out the right parameters for my camera but at least the problem related to addressing out of space seems solved. What do you think?
What board are you using right now? Both errors StoreProhibited/LoadStoreAlignment are related with the PSRAM and those lines in the main.c file. Thus, our boards may be different. It's good to know that the original main.c works with your board, but not with my ESP32-CAM and M5Stack.
The camera.init(0) is only for the ESP32-CAM module. If the camera is not found, you get the error 0x105.
Hi Mauro, thanks for replying.
As a matter of fact, the original main.c seems to mange the different kind of HW and in my case is working.
I am using this ESP32-CAM like this one https://m.media-amazon.com/images/I/71LGsWic1pS._SL1500_.jpg

I figure it out how to initialize camera and now is working
>>> import camera
>>> camera.init(0, format=camera.JPEG, framesize=5)
True

I will give a try to your uPyCam. I just want to thank you for your great work.
