IMX8MQ M4 UART problem.

siva3 — Fri, 24 May 2019 08:52:05 GMT

Hi,

I am using a IMX8MQ eval board from TechNexion, while playing around with the M4 Core of the SOC I noticed that in all examples provided I am not able to recieve using UART but am able to transmit without a problem.

I am using the SDK provided by them (SDK version 2.3)

I tried all UART recieve APIs but all in vain.

I checked the device tree files so as to make sure that the device tree initialization is not conflicting with what I have defined for M4 Core.

Link to the project

I even checked the hardware the UART singals are there till the SOC Pins.

I also tried changing ports but still no luck..

Any help would be appreciated..!!

Thanks in Advance

Hi,

I’m afraid that TechNexion boards are not supported by NXP. You could redirect your question directly to TechNexion on the following link:

Hope this will be useful for you.
Best regards!
