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
DFU State: STATE_IDLE
DFU Status: STATUS_OK
Request: Get Status Request.
Percent: 24% (may differ)
Thank you in advance.
