Hi, the device uses the PINs only, but not the spi protocol. It talks directly so the SX1278 via the PINs. This works in RaspberryPi standard images from scratch without any change (only disabling SPI). I don't know what you mean with "dtbo". I'm not a developer, only a user. Can you please give me some hints? Regards

Hi I'm using an Orange Pi PC Plus with a LoRa HAT (Semtech SX1278) connected via GPIO. The tool which uses this HAT connects directly to the SX1278 chip on the HAT, no protocoll like SPI is needed. I'm using it for several years on RaspberryPi's without problems. But with the latest ARMBIAN Image for the Orange Pi PC Plus Armbian_23.11.1_Orangepipcplus_bookworm_current_6.1.63.img.xz I have issues in this constellation. The tool can not contact the SX1278 via GPIO, said the tool developer. It seems like I have to activate the GPIO pins before. I've tried to find information about that, but without success. So I hope to find here more information and help. I have to use these hardware PINs (these are the PIN descritions on teh Raspberry Pi): MOSI SPI0_MOSI / GPIO10 (PIN 19) MISO SPI0_MISO / GPIO9 (PIN 21) SCK SPI0_SCLK / GPIO11 (PIN 23) NSS/Enable SPI0_CE0_N / GPIO8 (PIN 24) RST GPIO6 (PIN 31) Thanks in advance.
