I am experiencing some troubles with STM32L432KC USB Bootloader. I am using DfuSe Demo v3.0.5 to upgrade firmware. 

DFuSe firmware upgrade fails in 95% of situations. Both on our STM32L432KC project and on Nucleo-32 STM32L432 evaluation board. Also tried to upgrade with sample project hex files provided by ST. Same result.

Error Code: Bad state machine in firmware

TransferSize: 2048

DFU State: STATE_IDLE

DFU Status: STATUS_OK

Request: Get Status Request.

CurrentNBlock: 0x0000

CurrentLengths: 0x0005

Percent: 24% (may differ)

 

Thank you in advance.
