SPI development files for WinCE7 on Colibri i.MX6

SPI driver is integrated in v1.0 release. Where can I get header files and library for it to evaluate this function ?

You can download a sample from here:
http://docs.toradex.com/103227-iMX6SPITest.zip
Please consider that this is preliminary information.
Official support for SPI on i.mx6 will come trough our libraries, implementing the same API we currently have on Vybrid. If implementing the libraries will require modifications to the interface used by this sample your applications accessing it may need reworking to work on new releases of the i.mx6 windows CE image and BSP.
