Part Number: TMS320F280049
Other Parts Discussed in Thread: C2000WARE
Recently I encountered an issue concerning TMS320F280049.
The issue can be described as below:
We have made a new pcb board with the main DSP TMS320F280049CPZQ and then I programmed the code into FLASH using CCS 8.1.0.
When the program process is finished, I shut down the DC power and then re-power the pcb board. But the code can not run. By contrast, I programmed the same code into the TMDSCNCD280049M SDK. The code can run normally. Also, I have experiments using the demo code c2000ware\device_support\f28004x\examples\gpio and c2000ware\device_support\f28004x\examples\led , the same circumstances exist.
We have checked 3.3V and 1.2V DC power, and all the DSP power are normal. The crystal oscillator, JTAG pins and XRSn pin are also normal.
Moreover, I pull up an IO pin in initialization process before enter main-loop code, then programmed the code into CPU FLASH and then I re-powered the PCB. The IO pin is set high level. Next, I toggled this IO pin in main-loop function. It can not toggle b/w high and low level after program process.
So, do you have came cross the same issue? Can you offer me some good suggestion?
I am looking forward to your reply.
Thanks a lot!
