Hello

i made this first time so i can not conekt to Target

I have made all right bud no conection

[ReFlasher] Starting..
Info : auto-selecting first available session transport "hla_swd". To override use 'transport select <transport>'.

Info : clock speed 450 kHz
Info : STLINK V2J34S7 (API v2) VID:PID 0483:3748
[ReFlasher] Found ST-Link
Info : Target voltage: 3.270400
Error: init mode failed (unable to connect to the target)
[ReFlasher] Couldn't connect to target

hey i had the same error.

STM32 ST-LINK Utility v4.6.0 is very likely what you are missing with this tool update the stick without having anything connected after that everything should work as described


Read the instructions that solved my problem.

Hello!

Just wanted to give a small comment to the discussion. So it happened that I've encountered this thread when trying to flash the controller on my Ninebot Max G30LP. I've discovered an error in the flasher documentation. It appears that in the images provided as the guide to connecting the wires, the SWDIO and SWCLK are shown incorrectly.

As a more general comment - the controller for G30D and G30LP seem to be identical, minus one of the white connectors. The correct connection schema is provided here: https://rollerplausch.com/threads/st-li ... llen.4270/

Please update the flasher documentation (the image for G30D), since it can be quite confusing.
Also please add a separate image for the G30LP scooters.

Can you share a photo of the controller and how you connected the ST-Link?
