CCS: Access to DDR data pins in debug mode

Alvaro Garay

Tool/software: Code Composer Studio

Hi,

Is it possible to see the state of the 64 DDR data peripherals pins in debug mode? I read a post that CCS supports JTAG in boundary scan in debug mode, but I can't find the hardware register that shows me the state of the DDR data or address peripheral pins.

Best Regards,

Alvaro

Alvaro,

CCS and the XDS-class of debug probes do not support JTAG in boundary scan mode but instead only in debug mode, which allows to load code, run/halt/step, put breakpoints, inspect memory, etc. Therefore if you need to perform pin verification you need a solution from a third party such as Corellis, JTAG Technologies, Goepel, etc.

Hope this helps,
Rafael

Hi Rafael,

So the boundary scan in debug mode should allow me to have access to see the state of the DDR data pins?

Best,
Alvaro
