DFU and DFUSE for STM32L476 Discovery Problem

Hello,

I am having an issue with DFU downloading to a STM32L476 Discovery board.

- Compiled a simple LED switching application in IAR converted to DFU by the file manager (tried both bin and hex)
- Tested via ST-LINK - works fine
- Connected BOOT0 to 3V - the board presented itself as DFU
- Downloaded DFU
- removed BOOT0 connection, pressed reset - application does not start

Tried both DFUSe 3.0.5 and DFU tester in the package - same result - downloads but does not start. Also tried to set flash address to 0x080000000 during "to bin" conversion - no effect.

What could be a problem? Any help would be appreciated.
