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.
Yes the jumper ist back in its original position – „off“.
As I wrote I tried to flash the firmware but It didn’t work. It is still the version before, 1.3 I think. At the moment I can not communicate with the strompi3 at all.
