[Gumstix-users] connecting two verdexes with SPI

[Santeri H. <sa...@ta...>]

Hi all,
I'm having some difficulties with running one verdex in slave mode and  
the other in master.

If i understand the PXA27x manual correctly the master (CLK, FRM)   
need to send CLK but not  FRM-signals while the slave device has the  
CSS flag set, so I enable SSP on both and
wait for the CSS to clear at the slave side.

The problem is that the CSS signal never clears, and I'm not sure  
why.  :/

Has anyone tried using SPI in slave mode?

You can look at my test program (based on the SPI examples) at
