iolinker Evaluation Board JI11x-81L-B
Click the "JTAG Scan" button. The FPGA should be recognized and identified automat-
ically. If it fails, don’t forget to verify that the just made "Custom I/O settings" are still in
effect before retrying.
Choose "Erase, Program, Verify" as operation and select a *.jed file. You can now click
"Program" to transfer your new application onto the board.
Be careful: NVCM programming can only be done 9 times. For software testing,
choose "Static RAM Cell Mode" instead. What you program into RAM is reset
after the next power cycle, however.
5.3 Troubleshooting
Reasons for failure may be:
• Software issues – particularly verify that the programmer cable is recognized and the
custom I/O settings have been made; other USB serial devices or cables may cause
issues as well
• Issues with your JTAG cable
• Wrong wiring
• Board not supplied with power
• VCC_IO not in the allowed voltage range of your JTAG cable
• Damaged hardware
As a first step, always verify your wiring and the VCC_IO voltage.
