- Connected rasspbery pi zero with HAT GSM/GPRS/GNSS/Bluetooth by gold-pins.
- List item
- Switched UART to B-position Raspbian version: 9 (stretch)
When I used pwdrkey i have only PWR and STA leds lighting constantly in red and NET flashing 1 per 2/3 seconds.
I switched in raspi-config:
Interfacing -> Serial -> No (shell) -> Yes (hardware)
And when i come into minicom by: sudo minicom -D /dev/ttyAMA0 I cannot do anything, nothing happened except:
Welcome to minicom 2.7
OPTIONS: I18n Compiled on Apr 22 2017, 09:14:19 Port /dev/ttyAMA0, 17:27:44
Press CTRL-A Z for help on special keys
And on bottom bar:
CTRL-A Z for help | 9600 8N1 | NOR | Minicom 2.7 | UT102 || Offline | ttyAMA0
And now I can only disconnect power cable, because any keybord combination do nothing.
