JTAG / Toshiba TMPA900
-------------------------------------------------------------------------------

This is a set of example captures of JTAG communication to a Glyn Tonga2
eval board with a Toshiba TMPA900 (ARM9) microcontroller.

The JTAG adapter used was the FTDI FT2232H based Floss-JTAG (V0.2).

Logic analyzer setup
--------------------

The logic analyzer used was a Saleae Logic (at 4MHz):

  Probe       JTAG connector
  --------------------------
  1 (black)   TRST#
  2 (brown)   TDI
  3 (red)     TMS
  4 (orange)  TCK
  5 (yellow)  TDO
  6 (green)   RST
  7 (blue)    RTCK


glyn_tonga2_init.sr
-------------------

The following OpenOCD command was used:

  openocd -f interface/flossjtag-noeeprom.cfg -f board/glyn_tonga2.cfg \
          -c "adapter_khz 1000" -c "init"

(this runs the OpenOCD "tonga2_init" function too, which sets up clocks/RAM)

The sigrok command line used was:

  sigrok-cli -d 0:samplerate=4mhz --time 5s \
             -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>


glyn_tonga2_reset.sr
--------------------

The following OpenOCD command was used:

  openocd -f interface/flossjtag-noeeprom.cfg -f board/glyn_tonga2.cfg \
          -c "adapter_khz 1000" -c "init" -c "halt" -c "poll off" \
          -c "sleep 4000" -c "reset" -c "halt"

(only the last "reset" and "halt" are in the dump)

The sigrok command line used was:

  sigrok-cli -d 0:samplerate=4mhz --time 5s \
             -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>


glyn_tonga2_idle.sr
-------------------

The following OpenOCD command was used:

  openocd -f interface/flossjtag-noeeprom.cfg -f board/glyn_tonga2.cfg \
          -c "adapter_khz 1000" -c "init"

The sigrok command line used was:

  sigrok-cli -d 0:samplerate=4mhz --time 3s \
             -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>

sigrok-cli was only started a few seconds after the OpenOCD init/connection
to capture what happens when the user doesn't actively use OpenOCD commands.


glyn_tonga2_irscan_drscan.sr
----------------------------

The following OpenOCD command was used:

  openocd -f interface/flossjtag-noeeprom.cfg -f board/glyn_tonga2.cfg \
          -c "adapter_khz 1000" -c "init" -c "halt" -c "poll off" \
          -c "sleep 4000" -c "irscan tmpa900.cpu 0xe" \
          -c "drscan tmpa900.cpu 32 0"

This gets the 32bit contents of the IDCODE register (0b1110): 0x07926031.

The sigrok command line used was:

  sigrok-cli -d 0:samplerate=4mhz --time 5s \
             -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>
