Dear Michael, Yep didn’t got any prints. So tried a hack. a) Booted using uart 2 b) set the GPACON c) Copied the config from 0x12c2 to 0x12c3 d)tried to write a char 0x41 (A) on 0x12c20020 0x12c30020, I got output on UART2 but not on UART3. We would like to use both uarts. Have you used

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
