Although BIOS takes advantage of RTDX, it is not a requirement to have 
BIOS in order to use RTDX.  The RTDX libraries can be downloaded as a 
stand-alone product here:

Why are you limited to JTAG debug?  It can be easier sometimes to dump 
out info over a serial port.

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.
