Hi Vybhav,

But I am sorry I think I misunderstood your question. You are saying you are using two nordic nRF52840 DK boards?

Are you using the SPI Slave and the SPI Master examples unmodified from the SDK? If not you can try and test the examples from the SDK and see if you still have glitches.

Best Regards,
Marjeris

Hi Vybhav,

You can also open a private ticket and send your schematic and layout files to Nordic engineers so we can rule out any hardware issue.

Best Regards,

You may need a DSO for this kind of glitch analysis, as an LA won't show the actual wave form properly.

This could likely be the result of cross talk.
