In our board CPU is master and DSP is slave.

CPU driving clock to DSP.

The clock rise and fall time is poor shown 2.

Do you know why?

1. CPU clock output

2. CPU connector to DSP(AA21,Y20)

Hello Chen,

Are you using TI provided EVM or custom board ?

Which clock you are referring here ? Could you elaborate on this ?

When CPU is driving the clock to the DSP and having issues with the rise/fall time, you have to check at CPU side about clock output specification.
