It's difficult to find the cause of the problem with this minimal information.

I'll give you only a few ideas:

- is your fpga design fully timing constrained?

- does it meet timing?

- are you using reduced HAL drivers? If yes, try to switch to the full featured version

- is there any delay between one hello world print and the next one?
