| 5 | This is a set of example captures of JTAG communication to a Keil MCB2140 | |
| 6 | eval board with a NXP LPC2148 (ARM7TDMI) microcontroller. | |
| 7 | ||
| 8 | The JTAG adapter used was the FTDI FT2232H based Floss-JTAG (V0.2). | |

| 16 | Logic analyzer setup | |
| 17 | -------------------- | |
| 18 | ||
| 19 | The logic analyzer used was a Saleae Logic (at 4MHz): | |
| 20 | ||
| 21 | Probe JTAG connector | |

| 23 | 1 (black) TRST# | |
| 24 | 2 (brown) TDI | |
| 25 | 3 (red) TMS | |
| 26 | 4 (orange) TCK | |
| 27 | 5 (yellow) TDO | |
| 28 | 6 (green) RST | |

| 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> | |

| 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. | |

| 79 | keil_mcb2140_irscan_drscan.sr | |
| 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 \ | |
