How to read to DSP internal RAM through JTAG without Emulator (or CCS)

Hi Experts,

We want to read simple RAM data from DSP through JTAP with no emulator
( and CCS). How should we do it?
Your help is greatly appreciated.

Get the details on the JTAG protocol for your DSP from TI.  You might
have to sign some sort of NDA, but they do make it available to
companies like Spectrum Digital and all the other manufacturers of
JTAG debuggers and programmers.

Then design your own circuit and write your own code to drive it.

It is obviously possible, but only you can decide whether the time and
cost involved is worth more or less than the price of a ready made
JTAG debugger with drivers for CCS included.
