Greetings, could you share more info about the board? Is it a custom board or something off the shelf? Or would you rather not say? What modem is installed that is trying to be run for the preInit? |

this is the picture from the github issue I mentionned earlier : (liberatedsystems/RNode_Firmware_CE#18) I checked the wiring (and made a test sketch to communicate with the LoRa board. It works) from what I understand of my test, the crash happen due to a semaphore on the SPI bus. sx127x::sx127x(uint8_t index, SPIClass spi,... I tried to change the code to pass it by reference instead but now the init must fail somehow since I can't configure the LoRa modem |

Ok, I do see that in the other thread.. Did you start out by turning off things you don't need right away in your board config? And did you add a new one? Things like HAS_CONSOLE, HAS_DISPLAY, HAS_BLUETOOTH or HAS_BLE? That simplifies things because you don't have to worry about them breaking the board before you test them. And CONSOLE will turn off the WIFI, no Bluetooth will block off that part of the MAC address (or you can just stub that out then in the code.) It also makes the code smaller by leaving those code blocks out, in case you have an initial size issue with the firmware. |

I did in some test. It is not changing much as the modem initialization is among the very first thing that happen |

well we made progress. so far the board is booting and it was a semaphore issue. but now the LoRa modem is not switching to the right frequency when used with Reticulum. more test is required |

Hi,
I'm looking for help, tips, pointer on how to debug the following issue :
I'm trying to port the RNode firmware on the ESP32-C3.
here is my issue with my current progress : liberatedsystems/RNode_Firmware_CE#18
the TLDR is that the node freeze after the following happen :
when the software try to initialise the radio modem, the SPI beginTransaction function make the ESP32-C3 freeze.
using print statement, I traced the issue back to theses lines :
@jacobeva seems to believe it might be due to a stack issues. I tried to set a bigger stack as his fix suggested, but there is no behavior change.
I also tried to disable the SPI init (nathmo/RNode_Firmware_CE@2217fe0) which allowed the board to boot and respond to command but without much surprise, the radio don't work.
I believe it's a semaphore issue, but I don't know how to debug these kinds of issue. Especially since I don't see anything in the code that was run before that would have touched the SPI.
(assert failed: xQueueSemaphoreTake queue.c:1549 (pxQueue->uxItemSize == 0))
If someone with more experience than me could spend some time to look at it, I would be incredibly grateful :)
this is my version : https://github.com/nathmo/RNode_Firmware_CE
This is the crashdump I got :
