I have been working on a UART implantation with the
two McBSPs on a 6711 TI processor but I have been running into some problems. I have established transmit and receive on both channels (without any DMA functionality) but I seem to run into some problems when receiving information. I will transmits a packet of information to the McBSP and in the response (On the Host) I will expect to see something like 40286BFE. I often do receive the correct packet back but sometimes I get something that is off like 40282BFE. The change from a 6 to a 2 is fairly repeatable and I know that the McBSP is receiving the correct information else the software would not send a reply. Has anyone had similar issues with implementing McBSP as UARTs and have you seen this type of problem. I assume that the problem is related to clock skew when transmitting back the information but I am not certain of this. Any help would be greatly appreciated. Cheers and thanks! -Devin |
