Target Voltage: 0.23 V

This is insufficient voltage to power the device. Look at the user manual for how to power the device properly.

    Hello, how to set the voltage? I don’t understand the manual. How much voltage is needed to be adjusted to connect to ST-LINK normally

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    Hello, how do you need to restore normal operation? I don’t understand the manual very well. Is there any specific method? thank you
