I am running the cyfxusbspiregmode example and can't see any debug messages via UART.  If I run the cyfxbulksrcsink example, debug messages show up in my HyperTerminal screen so I know everything is connected correctly. 

   

I am connected to the FX3 using the J8.  Do I need additional hardware to get debug messages using spi since the UART moved from pins 53-56 to pins 46-49?

   

Thanks.

Hi,

   

Yes. The Pins 53 - 56 are only connected to the USB Serial Chip on the board (U3). So you wont be able to see debug messages for 46 to 49. You can use the USB Debug Feature for firmwares using SPI.

   

Please refer the USBDebug Example firmware.
