Description

When I use Meshtastic on Linux Native with the PineDIO LoRa USB, it crashes with the following error some time after initializing:

ERROR | 20:12:12 30 [RadioIf] Radiolib error -20 when attempting SX126X scanChannel!
program: src/mesh/SX126xInterface.cpp:311: bool SX126xInterface<T>::isChannelActive() [with T = SX1262]: Assertion `result != RADIOLIB_ERR_WRONG_MODEM' failed.

Sometimes I get this error instead:

DEBUG | 20:35:16 94 [RadioIf] Starting low level send (id=0x0ed98382 fr=0x8b to=0xff, WantAck=0, HopLim=3 Ch=0x8 encrypted rxtime=1727642100 hopStart=3 priority=100)
ERROR | 20:35:16 94 [RadioIf] startTransmit failed, error=-705
ERROR | 20:35:16 94 [RadioIf] NOTE! Recording critical error 11 at src/mesh/RadioLibInterface.cpp:481
free(): double free detected in tcache 2

Sometimes it crashes immediately, and in other cases I've let it run without interacting for hours before encountering the crash.

Steps to reproduce:

• Clone Meshtastic firmware
• Build for native with PlatformIO
• Configure for sx1262 and gpio in config.yaml
• Load spi-ch341-usb kernel module and connect PineDIO LoRa USB
• echo spidev | sudo tee /sys/bus/spi/devices/spi0.0/driver_override; echo spi0.0 | sudo tee /sys/bus/spi/drivers/spidev/bind (set spi device driver)
• Run Meshtastic

I have tried many times to correct this issue by checking my GPIO configuration and altering parts of the code.

OS: Arch Linux CPU: Intel i7-2600 Kernel: Custom build (config changes), based on 6.10.7

The only other Meshtastic device within range is my T-Beam in the same room running Meshtastic.

If any more details are desired I will be more than happy to oblige.

At least one of the problems is that the Busy line isn't actually connected. A developer is working on a replacement user-mode driver that's showing a lot of promise.

I have been directed to the CH341 branch, which is an exciting development. I think I'll close this issue, since bugs with the ch341 branch are off-topic here. Thanks!
