are you sure that µC is powered? I mean... do you hold the "start" button?

[tah-AMG]

i hold iiit before pulg iiin iit iin the stlink and berofe powering the board no difference how do i know if the board is bricked ?
also before compiling the code you only need to uncomment the variant that you want or there is something else you need to change

[iso14000]

you should check µC power , 3.3V

[tah-AMG]

i did the 3,3v and the battery power i will try plug in the whole board in the hoverboard that is my last move

[iso14000]

mmm , is it a ST or a counterfeit on the board?

[tah-AMG]

no GD32.. but says arm on boittom

[iso14000]

by the past a GD broke up without a known reason, do you use a genuine STlink dongle?

[tah-AMG]

i did plug all the cables and it behaived a bit but still does not connect to st link i use just the fake one i did all the combinations in the st link utility and even i pluged the 3.3v with a battery and same thing now just start up sound and nothing i remeber in the code i disabled one motor i think i will give up can u give me a hex file u know works and i will try it on another board but still same mcu gd32
and btw thanks for your help man

I'm working on the transpotter version. Making some adjustement such as "standstill" feature when leach is released.
So a little far away from your version
find attached a know working version .elf file.

I use a genuine STlink.
