Always in STM32 Bootloader mode with J-Link plugged

[jcook]

With J-Link plugged, no matter powered by USB port or not, connecting host via USB port will get a STM32 Bootloader device in PC's device manager list.

Seems Cannon it's under Boot mode with this setup that results APP code cannot run.
How to resolve?

maybe it's related to the BOOT0/BOOT1 pin selection issue.

Connected BOOT0 to GND, STM32 will not enter into boot mode.

But got USB enumeration failure when J-link plugged to PC.
There may have bugs in code somehow. Need to dig more.
