Hello I am new here, I try to flash the firmware i created from pioneerland to the new hoverboard mainboard i have.

I tried powering the mainboard from 36V battery, from the ST32 dongle(while disconnecting the battery) the red light is blinking when powered but i always get the same error as "cannot connect to target"

the cable connections are correct i checked 10 times already:) GND to GND CLK to CLK and DIO to DIO.

I was not able to unlock the unit as there is no clear tutorial about it. I am using windows 10. is it the problem?

Can anyone help please.

I am using Windows 10 without any Problem. Update the firmware of your ST-Link v2 dongle using the newest version of ST-Link utility.

  1. connect GND, CLK, DIO, connect USB
  2. connect battery
  3. press and hold power button of the mainboard
  4. flash
  5. release power button

Already did those. St link utility does not see the board on the first page.

Try to isolate the error: is it possible to flash another target?

Hi, I tried your way, i bought bunch of mainboards. 2 of them, same result. But i suceeded in 1 older version. I think in the newer versions some kind of hardware protection is available.

thanks.
