   5 This is a set of example captures of JTAG communication to a Glyn Tonga2
   6 eval board with a Toshiba TMPA900 (ARM9) microcontroller.
   7
   8 The JTAG adapter used was the FTDI FT2232H based Floss-JTAG (V0.2).

  32 glyn_tonga2_init.sr
  33 -------------------
  34
  35 The following OpenOCD command was used:
  36
  37   openocd -f interface/flossjtag-noeeprom.cfg -f board/glyn_tonga2.cfg \
  38           -c "adapter_khz 1000" -c "init"
  39
  40 (this runs the OpenOCD "tonga2_init" function too, which sets up clocks/RAM)
  41
  42 The sigrok command line used was:
  43
  44   sigrok-cli -d 0:samplerate=4mhz --time 5s \
  45              -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>

  48 glyn_tonga2_reset.sr
  49 --------------------
  50
  51 The following OpenOCD command was used:
  52
  53   openocd -f interface/flossjtag-noeeprom.cfg -f board/glyn_tonga2.cfg \
  54           -c "adapter_khz 1000" -c "init" -c "halt" -c "poll off" \
  55           -c "sleep 4000" -c "reset" -c "halt"
  56
  57 (only the last "reset" and "halt" are in the dump)
  58
  59 The sigrok command line used was:
  60
  61   sigrok-cli -d 0:samplerate=4mhz --time 5s \
  62              -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>

  65 glyn_tonga2_idle.sr
  66 -------------------
  67
  68 The following OpenOCD command was used:
  69
  70   openocd -f interface/flossjtag-noeeprom.cfg -f board/glyn_tonga2.cfg \
  71           -c "adapter_khz 1000" -c "init"
  72
  73 The sigrok command line used was:
  74
  75   sigrok-cli -d 0:samplerate=4mhz --time 3s \
  76              -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>
  77
  78 sigrok-cli was only started a few seconds after the OpenOCD init/connection
  79 to capture what happens when the user doesn't actively use OpenOCD commands.

  82 glyn_tonga2_irscan_drscan.sr
  83 ----------------------------
  84
  85 The following OpenOCD command was used:
  86
  87   openocd -f interface/flossjtag-noeeprom.cfg -f board/glyn_tonga2.cfg \
  88           -c "adapter_khz 1000" -c "init" -c "halt" -c "poll off" \
  89           -c "sleep 4000" -c "irscan tmpa900.cpu 0xe" \
  90           -c "drscan tmpa900.cpu 32 0"
  91
  92 This gets the 32bit contents of the IDCODE register (0b1110): 0x07926031.
  93
  94 The sigrok command line used was:
  95
  96   sigrok-cli -d 0:samplerate=4mhz --time 5s \
  97              -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>
