Hi all!
I have the NRF54H20 D and somehow the RTT viewer doesn’t work, the board doesn’t work. I am using the most simple zephyr hello world project. It says it is compatible...
Do we have KiCad version of nRF51822 QFN48 reference design? We looking at open source toolkits, including Eclipse, so KiCad comes into picture.
Thank you in advance!
The test code:
