I have also tried as follows:
jtag> cable parallel 0x378 WIGGLER
Initializing Macraigor Wiggler JTAG Cable on parallel port at 0x378
jtag> detect
jtag>
But then I get no answer from detect.
I think our processors are not supported :-(
JTAG-aware parts (chips):
- Atmel ATmega128 (partial support)
- Broadcom BCM1250
- Hitachi SH7727
- Intel IXP425
- Intel SA1110
- Intel PXA250/PXA255
- Intel PXA261/262
- Xilinx XC2C256-TQ144
- Xilinx XCR3128XL-CS144
- Xilinx XCR3256XL-FT256
To bad, this is just what I'm searching for.
