hi 

I tried the way you provided and it didn't help. Can you help use  nRF Connect SDK Build an HEX FILE for test , use NRF52840 and modify the UART PIN definition as follows
RX_PIN->P0.14
TX_PIN ->P0.13
HW FLOW CONTROL->Disable

thanks

Hi,

I have modified and built it for nRF52840 now, so please check if these hex file works.

Best regards,

Marte

hi 

It works very well on 52840dk, but it doesn't work on my own board. But I found that when I erase all, there will be uart data as shown in the picture below, do you have any ideas?

Hi,

From your picture it looks like it works, as that is how it should look when using the shell. Are you able to write any of the commands from the documentation I linked to, Radio test?

Best regards,

Marte

HI 

I can't see any uart data (no--booting zephyr....), until when I execute erase all, the uart data is out
