Hi Nagarathna,

I am also having the same issue. Did you find out how to resolve it.?

yeah I solved for evaluation board ,

u just reset the dsp using SYN PIN AND EN PIN as for datasheet and try it.

Hi Nagarathna,

Not sure which datasheet gives the use of SYN and EN to reset the DSP.

The waveforms and timing show only SYN and CS.

If what you intended is SYN and CS, there are still issues with the SPI working properly - especially if you use a number of the STPM3x with parallel SPI connections.

Any help on this?
