Solution:
Inspect Physically: Check the FPGA for any visible signs of damage, such as burnt pins or traces.
Test on Another Board: If possible, try using the same FPGA on a different development board to rule out hardware issues.
Replace Faulty Components: If any parts seem damaged, replace them and test again.
Conclusion
A failure to boot on the XC7A35T-2FGG484I can stem from several causes, including power supply issues, missing or incorrect configuration files, clock problems, or even hardware damage. By systematically checking the power supply, configuration settings, reset signals, and software/firmware tools, you can identify and resolve the issue. Always ensure your environment matches the specifications outlined in the datasheet and design guidelines.
