Hello,

I am writing a generic BSDL interface to support external access
to Flash and GPIO.  This is currently relative to OpenOCD 0.4.0.
I am using a Turtelizer2 cable to play with a TMS320VC5402 DSP.

I am running into lack of documentation on using the JTAG code:

1. When I tried to use jtag_add_statemove, I got error that it
   will not move _to_ the TAP_RESET state when I am requesting to
   move to the TAP_IRSHIFT state.  As it turns out, the first few
   transitions say "stay in TAP_RESET", causing these errors.
   I am not sure how to overcome this.

2. I found that first doing a statemove to TAP_IDLE avoids 1.
   During Flash reading attempts, my TRST signal is set to -1 so
   it seems that I am missing some initialisation; what call
   should be placed in what routine of the target?

I seem to have created a target in TAP_RESET mode and I cannot
find a way out.  Clearly, I am missing something about how the
JTAG functions are to be used.  What operations would you
advise?


Thanks,

Rick van Rein
