Hi,
I have configured SCIA peripheral to work for RS232 communications. I have executed my code on eZDSP evaluation board and i was able to communicate. Basically i was using RS232 to request the data from DSP mempry locations and using my application running on PC i was able to see the data. On evaluation board it was running, however in actual target it is not running. I am not able to receive the data. The only difference i observe between eZDSP and Actual target was clock. I have ensured the proper clock frequency and still i was not able to communicate.
Please suggest if iam missing any thing here. My RS232 configurations are:
Baud rate: 115200
Start/Stop bits :1
Parity : Odd
In addition, when i saw the SCIRXST register, iam getting Frame Error. Parity Error and Rx Error bits set to 1. I understand that these bits indicates error, but unable to figure out the reason. Also, i tried executing TI provided example program sciaechoback on evlation board as well as on target. I was able to communicate using Hyper terminal and echo back the data that i have sent from DSP. So, i dont see any problem in the COM Port configuration on target. I have compared the SCI configurations used in example program with my code, both are same except that iam not checking for TXRDY pin.
