Connect cross power-domain to UART00 on P2 of nRF54L15 DK

[Archiet]

Hi there!

May I know how to have UART00 on P2 like what is shown below as I wanted to have higher speed.

Is it the same as other UART assignments on P0 and P1?

Thanks!

Hi again,

I just changed the baud rate to 921600 in my serial port tool, then Tx of UARTE00 becomes readable text but it should be 115200 according to device tree I attached above . For Rx, it still cannot control LED of DK until I change it  to P2.07 with baud rate 921600. Do you know why the actual baud rate is different from my setting and why Rx as P2.06 is not working but P2.07? Look forward to hearing from you. Thanks!

I have the same experience.

for uart00, it works only with the dedicated pin function. not able to use P2.06 for rx. try changing to P2.07.

also observed that the baud rate on the terminal program must be 8x of the uart current-speed.

not sure if has anything to do with the peripheral clock frequency being 128 MHz in mcu domain?

Hello,

Can any of you please upload the application that you are using to reproduce this. It is easier, and quicker, for me to reproduce, and potentially forward to our developers if I have something that I can just build and flash.

Best regards,

Hi there!

I have attached my main.c, conf file, Cmake list and DTS file here.May I know what other files you need? Or should I zip the project folder and share here?

Preferably, yes. If I don't need to create my own application on top of a CMakeLists file and a couple of scattered files, it will be a lot easier for me to reproduce, meaning I will be able to do it sooner.

Best regards,
