Trouble with custom bootloader and CubeMX generated code

[xrstokes]

Hi, I've got an project in cubeide that starts in one project and then jump's to another at 0x0800C000. It's been working in the past and I've somehow broken it trying to do updates. Here is the main code in the bootloader. It's very simple. BOOTLOADER v

It's very strange. On the first power up it fails always in the app at "SystemClock_Config();" But if i reset the board. or power down and repower up in less than 10 seconds it gets past it. I've tried a bunch of different clock configs and a thousand hardware changes. Can't work it out.

Please Help.

OK, I deleted the projects and started again. Generated new code and it worked fine.
