Hello,

I am currently developing TMS320F28069M and for Chip to Chip communication i want to use McBSP (Multichannel Buffered Serial Port) for comunication with AM4377 on SPI interface.

How to shows belowe in Figure 6-7. On TMS320F28069M side McBSP pins are listed below;

MclkRA 94

MclkXA 98

MdRA 7

MdXA 6

MfsRA 56

MfsXA 2

Woud you please explain me how to connect pin to pin with AM4377.

Taner,

We have a SW example to help show how to use the McBSP as a SPI on this device here http://dev.ti.com/tirex/explore/node?node=AAgP0n4VK3pOnTuhOpB36Q__gYkahfz__LATEST

With regards to the AM4377, it looks like both SPID0/D1 data pins can be configured as SOMI or SIMO as you have shown above so you'll just need to route the DR/DX to them, and then configure as SOMI/SIMO to match the diagram you've attached. The CS on that device will funtion as the SPISTE(enable).

Let me know if you need more info on the above.

Best,
Matthew
