Uart doesnt initialize

[DevNovik]

Hello there,

I am that newby in the vs code dev environnement. I use the XM122 from acconeer to perform radar measurement. The soft provide by Acconeer compiles and works well in Vscode but i want to add the uart peripheral in order to stream data from other sensors.

When I initiatialize the uart (from the uart peripheral example; Nordic SDK 15.3) I got the following error ERROR 8 [NRF_ERROR_INVALID_STATE].

I am working on it for a while and really starting to be disappointed since what I want to do seems pretty simple.

Any solutions of this issue is welcomed.

Thanks in advance

Hi.

Are you using the example unmodified? APP_UART_FIFO_INIT() will return Invalid State if the module has already been initialized.

I have to modify the example on the XM122 board since that is not the same hardware. But at every init the code return an error. Then I have tried it in the real dev kit, i.e nRF52 DK and that works fine

Hi,

Seems that the issue is board dependent. Did you make a custom board file for your board?
