I am using UART sensors that do not allow the RPI to finish the boot when the serial console and the bluetooth are on. I did disable them using the
/boot/config.txt and deleted the serial console parameters from the
/boot/cmdline.txt, but the problem is that they are still on during the boot and they only get disabled after, which does not allow my pi to boot when I have my UART sensors plugged in. Does anyone know how this could be fixed?
EDIT: It might be that my pi does not boot because the sensors connected send garbage to the board, which cause my u-boot to stop at
hit any key to stop u-boot, hence I am thinking that setting that key to something pre-defined instead of "any key" could solve my problem. However, I don't know how to do that, could anyone help?
