About MKV56F512 programed problem

[gary_yang]

Dear Sir：

Hello, we are a third-party programmer manufacturer. We used SWD communication to program the customer’s code successfully, but the customer was tested on board and found that the UART could not communicate
What could be the reason or what is recommended to check?

Thanks

Hi @gary_yang ,

Do you mean if you use your own programmer to download the UART example code in SDK, the example can't run well?

Regards,

Jing
