RTL-SDR Extension Board with USB HUB and RTC

Hello @vileer , I have AIO v2 and my LoRa module suddenly stopped working after reboot with error:

SX126x init result -2
No sx1262 radio

GPS and SDR are working well. I’m using Rex’s Debian Trixie.

My config.txt:

As you can see I’m turning on only LoRa module on boot for power saving.

My cmdline.txt:

My meshtasticd config:

Lora:
  Module: sx1262  # HackerGadgets RTL-SDR/LoRa extension board
  DIO2_AS_RF_SWITCH: true
  DIO3_TCXO_VOLTAGE: true
  IRQ: 26
  Busy: 24
  Reset: 25
  spidev: spidev1.0

GPIO pin is turned on:

# pinctrl get 16
16: op dh pd | hi // GPIO16 = output
369

I have somehow removed this line from config.txt accidentally. Returned this line and LoRa is working again!

Everytime you enable the lora module, you should restart the meshtasticd service.
