Maybe you can help me as well. I am trying to get an Adafruit ESP32 S3 TFT board to work with FreeRTOS. I load the Adafruit Feather S3 TFT BSP. It compiles OK, no errors, but when loading it into the board, I get a hardware crash, and a bootloader display on the LCD screen. The code is listed below…

[image] rs77can: I increased the Stack to 512 - but no difference Your code from Post #1 crashed (with stack exceptions) when I tried it. It ran fine when I increased the stack size to 2000 bytes for each task. I even enabled the Serial.print lines and saw output in the Serial Monitor. I'm s…

[image] rs77can: Any ideas what to try to resolve this? What have you tried?

I see all the appropriate files in Arduino15 AppData folder (FreeRTOS.cpp and RTOS.h). I have tried running it on Platform IO (in case it was a corrupted IDE) , but get the same error. It is supposed to be a functioning library, but unless I am doing something wrong, there must be some kind of inc…

vTaskDelay(1) in arduino core is 1 ms not 15 msecs. So with it having a higher priority than the other task, it is taking nearly all the cpu time.

The program is strictly a cut and paste from online existing sample code. The 15mS may be the tick on older 8MHz Arduinos. The ESP32 CPU is 240 MHz, so 1mS delays should be OK. However, I changed the code to 10 mS and no change - [20231003_215151] the same happens - Arduino equivalent of BSOD

[image] rs77can: Any ideas what to try to resolve this? Run the crash report through the Exception Decoder and post the results. Try increasing the tasks' stack size.

[image] noweare: So with it having a higher priority than the other task, it is taking nearly all the cpu time. Starving a lower-priority task for CPU time by itself won't cause a crash ... especially not OP's simple code example.

[image] rs77can: there must be some kind of incompatibility between the board and the standard library. Right. I also have crashes with RTOS and some AdaFruit display libraries on my ESP32 board. Since a different display was working I didn't research the problem further. It may be a bus mat…

My only guess would be the board somehow uses the timer that is used by FreeRTOS, or maybe it changes interrupt vectors?? I posted the problem in the Adafruit forum as well, but have not received a reply yet. I ordered a different board (ESP32 also) with an integrated LCD display that another poste…

[image] rs77can: poster on a different forum said they had success using it with Free RTOS Did you take the steps suggested in Post #7 ?

I increased the Stack to 512 - but no difference (did not expect to, as I am doing nothing in the tasks that would use up stack) I am unable to run the exception decoder, and the reason is that the ESP32 S3 seems to not be able to reset via the USB connection. ESP32-S3 hangs on "Hard resetting via…

Run the crash report through the Exception Decoder and post the results.
Try increasing the tasks' stack size.
