I have a Banana Pi M2 zero and i need to use the SPI LCD (17344 waveshare) and a IR temp sensor MLX90614. At the beginning i tryed with Raspbian, where i managed to get the LCD working but i was not able to get the MLX90614 detected and readed on I2C pins. As a test i added an RTC module and everything worked as should. I searched about this problem and i have read some suggestions to move to Arbian. I tryed Armbian Focal and Buster, both mainline based kernel 5.8.y The result was to be able to read the MLX90614 on I2C, but now there is no way to get the SPI working.
. Any suggestion?
