Sysbuild example nRF5340DK UART output

[danny0007]

Hi Community,

I'm learning the sysbuild stuffs, try to upgrade my code to sdk v2.9.0.

Exercise 2 - Adding custom image - Nordic Developer Academy

I'm using nRF5340DK to run this exercise code, but I can't find the so called "UART30 " for output.

Could you please give me more instructions? thanks!

Regards

Danny

Hi,

Only the nRF54L15 uses the FLPR core. The nRF5340 uses the Network core, which is on UART0.

The COM port settings in Windows does not match to UART name

Hi Sigurd Hellesvik 

I want to upgrade my code to sdk v2.9.0.

Exercise 4 – DFU over USB 

Exercise 5 – FOTA over Bluetooth Low Energy

these two features I need for my use case, I know they are currently only supported for nRF5340DK. I tried to compile DFU over USB for thingy53, seems not working.

could you please share me how to make them also working for thingy53? because my board is similar as thingy53.

Hi Sigurd Hellesvik 

with this setup(nrf5340dk board), after build and flash, the nRF5340 USB is working.

even I flash this image on my board, the USB is also working.

*******************************************************************************

with this setup(thingy53 board), the USB doesn't show up at all.

I managed to make the USB working for both MCUBOOT and APP printk.
