I am trying to establish communication between my PC and my TMS320C28346 processor. I am using the TMS320C2000 DIM 168 Experimener's Kit.
I have imported the "scia_echoback" example program into CCSv4 compiled and run it.
My PC is connected via USB and I have established communication with my board. I can get the "Hello World" receive message from the echoback program.
Unfortunately, my board, or at least my MCU doesn't seem to be receiving data from my PC.
I can see the LED flashing when I hit my keyboard, and more importantly I have scoped GPIO28 and can see that data makes it there. However, the example program which continually pings on the RX status byte to see if any data has arrived never seems to see a change.
Could this be some configuration or jumper or something that I have neglected to set up correctly? I thought the example program should work without me having to change anything else. Looking at the board itself, it appears that a jumped needed to put into J13 in order to get the data to GPIO28. I have tried to execute the example with the jumper both on and off. Still no receive.
I am thinking that the fact that I can receive data without any issues AND the fact that i can see my data getting all the way to GPIO28 should exonerate my communication setup. So what leaves me not physically configuring my board correctly for SCIA communication?
Any ideas?
