I encounter the same issue.

All previous mainstream U-Boot and Altera U-Boot working properly.

But just pull to newer U-Boot that tedious message print.

However keep reset manually via master reset button can trigger a normal boot.

So it must be s.t. messed up on patches.

No it is not about the device issue, it is U-Boot software issue.
