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

Started by Xiaohu December 20, 2004
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. -- Jack Klein Home: http://JK-Technology.Com FAQs for comp.lang.c http://www.eskimo.com/~scs/C-faq/top.html comp.lang.c++ http://www.parashift.com/c++-faq-lite/ alt.comp.lang.learn.c-c++ http://www.contrib.andrew.cmu.edu/~ajo/docs/FAQ-acllc.html
Your information is  a great help. Thanks a lot.
