Pulse on PCS line during SPI transmission

[hongshengwang]

Hello,

When I run sample projects(like sbc_uja1169_s32k144) on S32K144 EVB, I can see pulse on PCS line during SPI communication. 

Has any of you seen this before?

Hello,

Have you tried with an oscilloscope instead of the logic analyzer? What is the duration of the pulse?
Maybe the connection is not good.

Regards,
Daniel

Yes, it's the analyzer issue. I don't see such pulses in the scope or analyzer from different company.
