Re: Development Issue on LPC55S69
2) I am not sure what you mean when you say “the voltage on the MOSI signal is unstable”. The Oscilloscope traces below look fine, however, the probes on your oscilloscope have not been properly compensated hence you see the ‘tilt’ on the signals instead of nice square waves. Take a look at this article to understand why and how to compensate your probes. https://www.circuitspecialists.com/blog/oscilloscope-probe-compensation-adjustment/

Subject: [Zephyr-devel] Development Issue on LPC55S69
We have some issues on developing LPC55S69 based on Zephyr OS.
I found the FW with this problem will link some more libraries as follows, maybe it cause the problem.
The following 4 situations happen:
If I open the counter drivers option in menuconfig, it will build fail.
Original source will assign incorrect ISR for the assigned pin.
Please help to answer these problems, thanks.
