Hello all,
I made a Wiggler clone by using 74LVC245A. I used this IC as it is 5V tolerant and my board works at 3.3V. I have used TMS, TCK, TDI, TDO, TRST and nRST. I used a 10 pin connector on my target board. The JTAG PCB is wired and not a proper PCB. When I run OpenOCD, I get a response stating TAP device found and later waiting for ACK messages appears and nothing happens thereafter. This message is displayed repeatedly, till shutdown command.
Why am I having this problem? Power to the 245 is drawn from the target which has the Luminary Micro IC (ARM7 Cortex M3). I await your suggestions. Thanks.
