SPI problem on i.MX53 with WCE 7

Using C# with VS2008.

Communicating with device at speed 100Kbaud, 8 bit, mode 0 and CS0.

When running in debug mode, it works perfectly.

When running the compiled program, it is not working.

Using a scope the difference is very clear

  • In debug, the 8 clock pulses are correct compared to the dataline.
  • In runtime, it seems like the mode changes to mode 1 (with the scope it then looks like there are 9 clock pulses)
