[Solved]: "SX126x init result -2" on RP2040-LoRa-HF

Raspberry Pi Pico (W)

Is this bug report about any UI component firmware like InkHUD or Meshtatic UI (MUI)?

No

Firmware Version

2.6.11

Description

Hi,

I got problems using a RP2040-LoRa-HF (https://www.waveshare.com/wiki/RP2040-LoRa) with meshtastic. I flashed firmware-pico-2.6.11.60ec05e.uf2 to the device using the Meshtastic web flasher and I'm able to configure the device using the original Meshtastic web client.
But the node doesn't seem to get any connection to other nodes - even if they are next to another on the same table. I always attached the antenna and different other nodes in my room can communicate with each other without problems.
My question is: Could it be a problem with the firmware I'm using oder maybe its a hardware fault? Looking at the serial debug output I think it could be hardware ("SX126x init result -2") but I thought I'd ask here before I return this device to the seller.

best regards,
Andreas

Also a second RP2040-LoRa-HF device shows the same SX1262 error, so I might do use a wrong firmware?

RadioLib documentation has this to say about error -2: "RADIOLIB_ERR_CHIP_NOT_FOUND (-2)
Radio chip was not found during initialization. This can be caused by specifying wrong chip type in the constructor (i.e. calling SX1272 constructor for SX1278 chip) or by a fault in your wiring (incorrect slave select pin)."

[fifieldt]

It looks like you're using the Rpi Pico firmware rather than the Rpi 2040.

[sparafucile]

As the Rpi Pico is a board that uses the RP2040 I thought it would do. But I found out that the SX1272 GPIO pins on the waveshare board are different. I found a firmware variant "rp2040-lora" that uses the correct GIO definitions. After building that everything runs as intended. Yay! ;)
