I'm running FUS 1.2.0 on an STM32WB55CEU and every time I try to update the BLE firmware over USB I get a FUS image write error. It appears to download and verify successfully but always fails during the actual firmware update. I can't seem to find this error anywhere else on the forum (or Google) so am I the only one having this issue?
