I'm currently working with a TI Firestorm part and trying to use OpenOCD for
debugging. I'm currently using the Olimex ARM-USB-TINY-H dongle (but get the
same results with the Luminary ICDI dongle). Here's my openocd.cfg file:
source [find interface/ftdi/olimex-arm-usb-tiny-h.cfg]
adapter_khz 100
transport select jtag
proc init_targets {} {
reset_config srst_only srst_open_drain
}
source [find target/stellaris.cfg]
When I first start up OpenOCD, it correctly recognizes the part and gives no
errors. Via the telnet port, I can also issue the "halt" command which
succeeds. However, if I attempt to issue a "reset halt" command, I get this:
> reset halt
adapter speed: 500 kHz
cortex_m reset_config vectreset
Resetting Core Peripherals
JTAG tap: lm3s.cpu tap/device found: 0x4ba00477 (mfg: 0x23b, part: 0xba00, ver:
0x4)

I have reduced the speed all the way down to 5kHz (both in my config file and
also in the stellaris.cfg file) but get the same results. I'm not sure how to
troubleshoot from here, but here's a partial dump of the -d3 data after issuing
the "reset halt" command:

Something has made it unhappy, but I'm not entirely sure what. Any clues to
where I can look next? I believe this is the last impediment to my fully using
OpenOCD and gdb on this target. Thanks!
