Hi am working with the MCF5235QSPI - ADC interface. I noticed that the CS signal out of the qspi is between 0 and -0.25 when i read the signal on the scope. I dont think this is a valid chip select. can someone plz let me know ur view on this

Hello,
Which hardware are you using, MCF5235EVB Evaluation board ?
 
How are your QSPI Chip Selects Configurated, GPIO or QSPI CSn ?

Bye,
