Hi, Not sure it will help but I recently tried to use a Semtech LoRa radio with an Arduino Zero and using a second SPI (for the radio) was working with the following configuration: { .dev = &SERCOM1->SPI, .miso_pin = GPIO_PIN(PA, 19), .mosi_pin = GPIO_PIN(PA, 16), .clk_pin = GPIO_PIN(PA, 17), .miso_mux = GPIO_MUX_C, .mosi_mux = GPIO_MUX_C, .clk_mux = GPIO_MUX_C, .miso_pad = SPI_PAD_MISO_3, .mosi_pad = SPI_PAD_MOSI_0_SCK_1 }
in the driver params, I had this line for the SPI: #define SX127X_PARAM_SPI (SPI_DEV(1)) Let us know if it works for you.
