We are implementing a product based on STM32L476VG and need to use DFU
To test the procedure we used STM32L476VG Discovery board. The following issue has been found:
- Compiled a simple LED switching application in IAR converted to DFU by the file manager (tried both bin and hex)
- Tested via ST-LINK - firmware works fine
- Started DFUSE utility
- Connected BOOT0 to 3V, reset - the board presented itself as DFU
- Downloaded DFU
- removed BOOT0 connection, pressed reset - application does not start
Tried both DFUSe 3.0.5 and DFUTester in the package - same result - downloads OK but does not start.
Also tried to set flash address to 0x080000000 during "to bin" conversion - no effect.
Same setup, same host tested with STM32F071 works without a problem.
What could be a problem? Any help would be appreciated.
