[OpenOCD-user] support for sa1100

[Diego R. <di...@ti...>]

Hello,

  I'm trying to use openocd for debugging a intel sa1100 board (this
one: http://www.lartmaker.nl/). Following the manual I've created the
following configuration file:

# --------------
interface parport
parport_port 0
parport_cable triton
adapter_khz 500

# reset_config trst_only

jtag newtap cpu arm -expected-id 0x9108406b  -irlen 5

target create sa1100 arm720t -chain-position cpu.arm
# ---------------

The cpu seems to be recognised:

But I can't halt the cpu or reset it:

sa1100: how to reset?

Any suggestion?

Thanks in advance,
