Read their posts and I am now trying the JTAG method.
I bought a JTAG to lpt cable online sometime ago for programming the xbox glitch chip and the seller claims the cable is made after the official xilinx schematics(buffered). (The cable worked well programming the xilinx chip by the way). The jtag end of the cable has TDI,TCK, VCC,TMS,GNC,TDO lables on its pins. From what I read online, the JTAG heads on my router is MIPS EJTAG 2.6 compatible so I just connect the pins as :
router JTAG cable
However, when I tried to use the tjtagv3 tool with -probeonly I always get a all zero CPU id. The option /cable:DLC5 won't help.
If I use tjtagv2 to probe my router,I was able to get a CPUid of 0006107F but my router wasn't supported by tjtag v2.
I also made an unbuffered JTAG lpt cable, still no go.(As a side note, the only computer with a LPT I have is a old thinkpad and the simple unbuffered JTAG won't let me to problem my xbox glitch chip neither.)
