Notes
JTAG protocol communication is a very vulnerable protocol, please avoid interference.
- From JTAG connector to target IC layout please follow the high frequency signal requirement.
- Make sure the PC end of USB balster can supply sufficient power, no interference and no any other USB device use together.
- Eliminate the interference source, such like cell phone, and shorten your USB cable
- if any communication error happened, reconnect the programmer, and restart Quartus II software.
