How to enable UART3 and UART4 in iwave imx6qdl pico SBC board?
The device is linux-iwave/arch/arm/boot/dts/imx6dls-iwg15s-pico.dtsi
is any additional settings to enable this ttymxc2(UART3_RXD(EIM_D25)) and ttymxc3(UART4_RXD(KEY_ROW0)) ??
Thank you

How to test the loop back for UART2 using ttymxc2 for the mira-imx6-15 in the expansion header ? What are the pins for that ?
Hi kk
please look at i.mx6q sabre ai board example (imx6qdl-sabreauto.dtsi) which uses uart3
linux-imx.git - i.MX Linux Kernel
check in uboot/include/configs/mx6qsabreauto.h for :
#define CONFIG_MXC_UART_BASE UART4_BASE
#define CONSOLE_DEV "ttymxc3"
Best regards

Hi igorpadykov,
Thanks for reply.
I tried with suggested changes, but UART3 is not transmitting or receiving any data.
[Hardware pins are UART3_RXD (EIM_D25) and UART3_TXD(EIM_D24).
no rts cts pins.]
Please guide.
Thank you
Hi kk
one can attach jtag debugger and check uart clocks
in CCM_CCGRn registers and pin iomux settings using
IOMUXC chapter Reference Manual.
Best regards
