Ninebot GT2p control board nRST pin diagram

[GT2PNewbyFlashr]

Hi does anybody know how to locate the nRST, pin on a GT2p, control board? When I connect st link it says UR connection needs SWrst which says I need to find the nRST, pin.  to connect another wire that goes from St link, v2, clone

to the nRST,  pin or button on the GT2p, control board. I can take a picture of what the PCB, looks like in about an hour? Thanks

First identify the chip and look at the datasheet to see which pin is NRST.

On commercial products, the chip may be locked in RDP level 2 in which case ST-Link will be unable to connect. Contact the manufacturer to find out that info.

What are you trying to do?

Stm32F405 I’m trying to change the

serial number to a Chinese serial number so I have all the bells and whistles and lights

Do you know how to do that? Have others done it and reported success? If it's a region-locked thing, the manufacturer probably did something to avoid this.

Hold BOOT0 high during reset (and BOOT1 low), connect to the chip using GND/SWDIO/SWCLK in STM32CubeProgrammer. If it doesn't work, the chip is either locked out or you've made an error in wiring. Since I don't physically have the board, not much else I can help with here.
