   5 This is a set of example captures of JTAG communication to a Keil MCB2140
   6 eval board with a NXP LPC2148 (ARM7TDMI) microcontroller.

  32 keil_mcb2140_init.sr
  33 --------------------
  34
  35 The following OpenOCD command was used:
  36
  37   openocd -f interface/flossjtag-noeeprom.cfg -f board/keil_mcb2140.cfg \
  38           -c "init"
  39
  40 The sigrok command line used was:
  41
  42   sigrok-cli -d 0:samplerate=4mhz --time 5s \
  43              -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>
  44
  45
  46 keil_mcb2140_reset.sr
  47 ---------------------
  48
  49 The following OpenOCD command was used:
  50
  51   openocd -f interface/flossjtag-noeeprom.cfg -f board/keil_mcb2140.cfg \
  52           -c "init" -c "poll off" -c "sleep 4000" -c "reset" -c "halt"
  53
  54 (only the last "reset" and "halt" are in the dump)
  55
  56 The sigrok command line used was:
  57
  58   sigrok-cli -d 0:samplerate=4mhz --time 5s \
  59              -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>

  61
  62 keil_mcb2140_idle.sr
  63 --------------------
  64
  65 The following OpenOCD command was used:
  66
  67   openocd -f interface/flossjtag-noeeprom.cfg -f board/keil_mcb2140.cfg \
  68           -c "init"
  69
  70 The sigrok command line used was:
  71
  72   sigrok-cli -d 0:samplerate=4mhz --time 3s \
  73              -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>
  74
  75 sigrok-cli was only started a few seconds after the OpenOCD init/connection
  76 to capture what happens when the user doesn't actively use OpenOCD commands.

  80 -----------------------------
  81
  82 The following OpenOCD command was used:
  83
  84   openocd -f interface/flossjtag-noeeprom.cfg -f board/keil_mcb2140.cfg \
  85           -c "init" -c "poll off" -c "sleep 4000" -c "irscan lpc2148.cpu 0xe" \
  86           -c "drscan lpc2148.cpu 32 0"
  87
  88 This gets the 32bit contents of the IDCODE register (0b1110): 0x4f1f0f0f.
  89
  90 The sigrok command line used was:
  91
  92   sigrok-cli -d 0:samplerate=4mhz --time 5s \
  93              -p '1=TRST,2=TDI,3=TMS,4=TCK,5=TDO,6=RST,7=RTCK' -o <filename>
