how to capture variables to PC realtime with jtag on C55x

hi, guys in dsp group
now, I'm working on C55x, and need to capture variable to PC
realtime with Jtag for the purpose of debugging. For my system, there
is no DSP/BIOS, so the RTDX can't work. I'm trying the Gel or Perl
script to do this. Is it feasible? thanks for ur comments.

my requirements:
#1. no dsp/bios support, so, RTDX can't work
#2 capture huge data from DSP target to PC for debugging.
#3 should not interrupt the DSP running when catpuring the data.

thanks for ur time. Start a New Thread
