GPIO Serial Mux

Question

Hello,
I am trying to select the GPIO function that is mux'ed with Serial port B on this ConnectCore Wi-9C board. I have changed in #define BSP_GPIO_MUX_SERIAL_B to BSP_GPIO_MUX_INTERNAL_USE only in the gpio.h file. I have also tried disabling the serial driver for serial port b in the bsp.h file. When I try toggling this port there is no effect. I have been successful doing this with GPIO pins that are not multiplexed. This is all with net os 7.0. Any help would be greatly appreciated.

Make sure you're using the NAconfigureGPIOpin to configure the GPIO pin (checking the return value), and then use NAgetGPIOpin and NAsetGPIOpin to change the GPIO values.

If you really want to bypass the APIyou can go directly to the appropriate registers, see the 9360 hardware reference guide for details.
