CCS/TMS320VC549: Reading and Writing IOPORT in Debugger

Paul Nicholson

Part Number: TMS320VC549

Tool/software: Code Composer Studio

How does one read and write to IOPORTs in the debugger. When the memory window is set to IO nothing shows. Moving the cursor over the memory display window displays the error:

Address 0x0

Error: Memory map prevented reading 0x0000@IO.

If you type "PORT_READ 0" in the Scripting Console you get:

TypeError: PORT_READ is not a function, it is java.lang.Double.

So how does the beleaguered programmer read an IO port on a c549 with CCS 5.5?

Thanks, Paul

Hi Paul,
I tried this out with CCSv5.5 with a VC549 EVM. It seems to be able to read it fine. I suspect an issue with the gel file. Which startup gel file are you using (if using one at all)?

Thanks
