F4 platforms don't boot correctly after LP-512

Description

Hello guys,

did anyone test the current next on an F4 platform?
I upgraded both a revolution and a sparky 2. Both fail to boot after the upgrade.
Reverting the F3 patches () fixes the boot problem.
Also tried reflashing the bootloader. Didn't help.
The bootloader seems to work. I get the blue "heartbeat" when I only flashed the bootloader.
With the firmware flashed, the blue led stays on for about 4 to 5 seconds. Then goes out for a short time.
This pattern seems to repeat.
Any idea how I can help troubleshoot this further? I don't have an ST-link2. But I have a clone on order.
I must say that I have have a few custom patches built-in, however I wanted to ask first if anyone else saw the same problem before I test with a clean build of next.
