Hi,
We are trying to enable the UART3 on COM18 pins of arndale board. The UART3 RXD and TXD are on pins 2 and 4 which as per the base board specification is connected as
XuRXD3 : UART_3_RXD/GPA1[4] : 2 XuTXD3 : UART_3_TXD/GPA1[5] : 4
As per the public reference manual of exynos 5250, there is a register GPACON (0x1140_0000) Setting GPACON |= 0x0010_0000 should enable the pins, but I am not able to see any output on UART3.
Can you please suggest what is the right procedure
