52840 UART1 couldn't receive data but could send data for NCS 3.2.4

[John]

Hi，

We use 52840 based on NCS3.2.4，add UART1 to blinky example because I need to use UART0 to log and UART1 to communicate with MCU for our application. 

The UART1 could send data but couldn’t receive data. The test code as attachment，could you help to see what the issue is？


Also I have tested in peripheral uart example，I meet the same problem.

Hello,

You are working on custom board or nrf52840Dk? 

''Also I have tested in peripheral uart example，I meet the same problem.'' You tried to run this on custom board or nRf52840DK?

Hi Kazi,

It's working on nRF52840DK,PCA10056 v3.0.1. The peripheral uart example is also run on nRF52840DK. Also I have set the pin of UART1 in the overlay, and selcet the UART1 for the peripheral uart example:

/ {
    chosen {
        nordic,app-uart = &uart1;
    };
};
