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 startTried 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.

Hi ferentes,

It will be better to follow one only thread for the same subject. So, putting responses in this [DEAD LINK /public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/DFU%20DFUSE%20problem%20with%20STM32L4%20%28STM32L476VG%29&FolderCTID=0x01200200770978C69A1141439FE559EB459D7580009C4E14902C3CDE46A77F0FFD06506F5B&currentviews=19]thread.Regards

Hi,

It looks like i am facing similar issue as reported in this post. For some reason i am not able to OPEN the link shared by @slimen​ . Could you please share working link. Your help is much appreciated.

Digging further, it looks to me like the last incomplete page (<2kBytes) of application image is not copied to STM32L476 FLASH at all when programmed using DFU mode.

Regards,

Suhel
