| 1 # The Calypso target is connected to an unbuffered FT2232D adapter | |
| 2 # acting as the JTAG interface following Mother Mychaela's method, | |
| 3 # ADBUS7 is wired to the reset pin on TI's 14-pin connector. | |
| 4 # This OpenOCD config sets up the TAPs and the ARM7TDMI target | |
| 5 # in order to test OpenOCD's ability to halt with and without the | |
| 6 # "Calypso magic" that has supposedly been sniffed from TI's CCS | |
| 7 # by people who came before me. | |
