SPI demos not working (LPC54608)

We're developing on the OM13092 dev board.

 

Neither the spi_polling_transfer or the spi_interrupt_transfer examples from SDK 2.2.0 operate.

 

The hello_world, touch_cursor (LCD), lcdc_tft and LED examples do operate properly.

 

FC9 clock is OK (coming out of FC9_SCK)

 

but FC9_RXD_SDA_MOSI and FC9_CTS_SDA_SSEL0 are not operating (viewed with O-Scope).

 

In the spi_polling_transfer example the program hangs at:

  while(slaveFinished != true)   because of no data out of fc9, no data into fc3. 

 

A jumper has been placed on JP6

 

Any ideas?
