Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled.

[richtigerprashant]

Hi,
I just installed the latest version from the main branch successfully from with pio (console). Now the start screens shows up, display shows after some seconds LoRa initiated and then switches to the overview or dies after a while. Then it goes into an endless loop of restarting as it seems.

Board is a LILYGO T-Beam Meshtastic LORA32 433MHz SX1278

I found this on the monitor console

Anyone knows how to fix this?
Thanks

figured out its happening when the device got a fix and might try to send it goes into the failure.

I get similar exceptions here, on a T-Beam 1.2

They occur after a GPS fix is achieved. To me this looks like a memory corruption of some pointer.

Also, they seem to happen in different locations, reproducible with the debug binary:

I spent quite some time on fixing this without success. I switched to the version from https://github.com/richonguzman/LoRa_APRS_Tracker and from there its working.

Thank you for replying, highly appreciated! I switched as well and everything works!

[dc0sk]

Despite this does not belong here, I'll be happy to help you out. That is most likely because you did not flash the file system with the json config. It is described in chapter 04 of the documentation or here https://randomnerdtutorials.com/esp32-vs-code-platformio-spiffs/ 08.05.2024 12:06:57 Edouard Griffiths ***@***.***>:

yes you have to flash the filesystem and then it works
