TMS320C6748: Testing SPI0 and SPI1

Lohith

Part Number: TMS320C6748

Hi,

I am trying to test SPI0 and SPI1 interface on TMS320C6748 board. It looks like SPI0 is routed to J15, however I don't see any clock or data signals when transmitting data.

Could you please point me to example code (with pin-mux settings) to test SPI0?.

It looks like SPI1 is routed via J16 which needs special cable to access SPI1 pins!, can SPI1 lines be accessed from alternate point on board ?.

Note: planning to test SPI0 and SPI1 with external devices.

Thanks,

Hello LC,

Please refer to the OMAP-L13x/C674x resources and FAQ and look for omapl138_c6748_ccs_projectspecs.zip. Once you download the CCS projects, you'll find SPI_LoopbackExample.

Please note that we can no longer support SW development for C6748 as announced here. So most likely we won't be able to provide further help here.

Regards,

Jianzhong
