So take everything with a grain of salt and correct me where I might be wrong/forgot. > I am not sure if I need to load the PN544 (I2C) driver? Yes, the driver is needed, for PN547 it’s NXP NPC100, the driver is drivers/nfc/nxp-nci. > Do I need these firmware files installed? To start with, i.e. for a simple signal through like reading a tag, most likely not (the chip is usually provisioned with some FW). Regards, Oleg
