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.
I’ve just asked my colleague of the RMA-Departement – as it seems the replacements of the StromPi3 was sent to you on 05.12, so it should have arrived to you already or should reach you any moment.
