Hello,
I have some issues with my nucleo board . I hadn't used it for a long time. Recently , i tried to handle it again but i don't succeed to download any program in the microcontroller. I get some messages error as STLink USB communication error or still No target detected . Naturally, i tried to look at potential solutions in the internet but until there the problem remains .
Need help !
Thanks in advance .
uVision V5.24.2.0 STLink Firm. version : V2.J29.M18 STM32 Debug + Mass storage

Ok, so that tells up nothing. Not what remedies you tried, or if/how they failed.
Strap BOOT0 pin high and try to Flash -> Erase
Check also with ST-LINK Utilities, but make sure you don't have an active connection in any other application when trying to connect with Keil
Check jumpers on the board. Check voltages at the part.
Hi , I've finally found my problem. I've compared my board to another one and i realized that the IDD connector was off . I 've just added a new connector and it works . So thanks for support .
This is an example of where using the ST-Link Utility would have helped - as that would have shown you the Target Voltage.
