I have an application on the K22 that gets bootloaded by the KSDK 1.1.0 bootloader. The bootloader and the application both use USB. I've found that I need to manually reset all the USB registers after the bootload to get my application's USB to work. Has anyone else come across this? I guess I would have thought that the bootloader (FSL_Kinetis_Bootloader_1_1_0) would do this before jumping to the application. Maybe I'm missing something.
