How to use UART3 of 6ULL as a common UART?

[jackjiang]

Dears,

UART3 is used as a Console in the SDK,  after we commented out the Console part of the SDK in imx.c file, UART3 transceiver exceptions.

Can you provide a UART3 as a software demo for common UART?

See the attachment for the DTS and DTSI file.

Hi Jack

in imx6ull.dtsi one can replace compatible = "ti,imx3100q-uart"; 

with compatible = "fsl,imx6ul-uart"

uart3 example can be found in some third party boards, for example TechNexion imx6ul-pico board

linux/imx6ul-pico.dtsi at tn-imx_4.9.88_2.0.0_ga-test · TechNexion/linux · GitHub 

Best regards
igor
