Issue with Altera MAX10 FPGA Development Kit and "MAX10 JTAG Secure Unlock" Example
Dears,
I am writing to request assistance regarding an issue I am encountering with the Altera MAX10 FPGA Development Kit. Specifically, I am working on implementing the example project "MAX10 JTAG Secure Unlock" using the reference design from the "an556-ref-design" project.
After successfully downloading the project to the FPGA, I initiated the JTAG lock procedure as described. However, I am experiencing the following issues:
When I attempt to erase the FPGA, I receive the following error:
- Error (209012): Operation failed
When I try to reprogram the FPGA, the following message appears:
- Error (209014): CONF_DONE pin failed to go high in device 1. Make sure all communication cables are ...
Additionally, I have verified that the CONF_DONE pin remains high at all times.
I would also like to ask about the behavior of the JTAG interface. I instantiated the WYSIWYG atom primitive, which, according to my understanding, should disable the external JTAG interface. However, the "Auto Detect" click continues to works, and I am still able to scan the JTAG chain.
Could you clarify why this is the case?
I would appreciate your guidance on how to resolve these issues, as I am currently unable to erase or reprogram the FPGA.
Thank you in advance for your support.
