STM8/128-MCKIT Motor control starter kit always shows 'Under Voltage' fault. How can I fix this?

[BLuck.2]

I have a STM8/128-MCKIT motor control starter kit. I am following hardware configuration specifications, but I keep getting the 'Under Voltage' fault. I am using the default BLDC motor and board configuration with an external power supply. Thanks ahead of time for any assistance. If there is any extra documentation for this device, that would be great. A video showing the setup process would also be great.

Welcome, @BLuck.2​, to the community!

The STM8/128-MCKIT was discontinued some time ago, so there is no documentation or information available from STMicroelectronics. However, you could browse the never-forgetting internet with your favourite search engine to see if you can still find documents such as the UM0709.pdf.
