Hi,
Could you please let us know if you have selected ICE Pick or ARM debug
mode from the EMU0 and EMU1 ?
note: ICE Pick Mode may have an issue booting from Reset !
For ARM Mode please configure your jumper for EMU0 = '0' and EMU1 = '0'
(pulldown 2.2k or smaller).
note : you could still route the SRST (ARM RESET signal) from the
Amontec JTAGkey-Tiny to the ARM_RSTn signal on your DM355 board. (eg. on
pin 15 of the TI SAMTEC 20-pin header).
If you want to use the RTCK (adaptive return clock ) signal, you could
update your ICE to an Amontec JTAGkey-2 dongle. This will help
accelerate your debug and help to have a stable debug.
That's just some comments. Maybe they could help, maybe not.
Regards,
Laurent

Hi folks,
I am trying to get OpenOCD 0.4.0 (built from git) working with an Amontek
JTAGKey-Tiny. I am using a home-made adapter to TI 14-pin JTAG header which has
TRST but no SRST, on our board which features Texas DM355 and one other chip in
the scan chain (which I don't care much about). For info we have been using the
Ronetix PEEDI JTAG programmer through the same connector successfully on this
board and other copies, so the design and connector are known to work.
I used OpenOCD a little a couple of years ago and it's clearly come on a long
way - I'm keen to play with the NAND flash support.
I have copied dm355evm.cfg and customised with a couple of lines like:
jtag newtap penta tap -irlen 5 -expected-id 0x04040009
# paranoia / trying to make stuff work:
jtag_rclk 100
reset_config trst_only separate
I can talk to the board a little, but I think I need to configure OpenOCD with
a software reset or something to replace the missing SRST?
