Hi Guys,
I have a very simple question realted to serial communication via the provided UART interface of beaglebone.
We have a very simple RFID reader TX/RX line, it is connected via UART4 on beaglebone.
My pinmux config is the following:
static struct pinmux_config uart4_rfid_pin_mux[] = {
{"gpmc_wait0.uart4_rxd_mux2", OMAP_MUX_MODE6 | AM33XX_PIN_INPUT_PULLUP},
{"gpmc_wpn.uart4_txd_mux2", OMAP_MUX_MODE6 | AM33XX_PULL_ENBL},
{NULL, 0},
};
I realise that all the UART lines are there after boot whether you use it or not.
My question is do I have to do anything else from the pinmux or I cane proceed with open("/dev/ttyO4", flags) stuff and start reading the serial line.
Thanks in advance!
Best Regards,
