After enabling double buffering my custom system suffers a single hardfault each time its power cycled. After a software reset NVIC_SystemReset() the system functions normally until the next power cycle.CFSR and HFSR show a FORCED UNALIGNED hardfault...

I'm glad you found it! I wasn't seeing the problem from your post.Would you consider posting a few lines of your code where you found the error to help others in case they have the same problem?

I may have found a possible cause.My MX configuration had what seems like a random arrangement of LOW and VERY HIGH for the maximum output speed of the LTDC GPIO pins (this was auto-generated by MX, frustrating). This translates into low/high slew r...
