Is it approved development board or custom design? In the latter case you should consider signal quality problems related to design.

To troubleshoot the apparent programming error, you might read out flash data with programmer and check the differences.

Hi FvM,

It's a Custom design based on Cyclone V & EPCQ64/EPCQ64 Serial interface flash. This is not a new design and being in production from 5/6 years. I am still checking, but so far, no apparent Signal quality issues are observed.

I ran the examine function after programming and it's susscesful.
