I set the strompi3 on my Pi3B+ to wide/battery. Yesterday I tried to flash the 1.4 firmware but the strompi is not responding at all.
When I try to flash the firmware stm32flash returns „Can not Init“ or something similar. The serial console returns nothing after typing in „startstrompiconsole“. Nonetheless the LED(s) on the strompi3 are on and the battery is beeing charged.
When I power the strompi3 with mUSB only (No wide Input, no USB power at Rasperry Pi) the wide LED is lid at the strompi3. The Raspi is not starting in this case.
