Hi,
I am testing a QSPI NOR FLASH device on a board I designed. Although it is working, I am seeing some glitches on the SDO (serial output of FLASH) line. All other signals (inputs look fine).
I believe it is working because glitch goes away before clock edge happens.
Looks like glitch is happening on a transition boundary (ie when the signal could switch from 1 to 0 or 0 to 1 but won't).
I have attached some photos showing this. Any idea on what could be causing this?
Thanks!
