The board is set up as follows, and USB of ST-Link V2-1 is connected to Host PC.

when using Linux host pc , /dev/ATM* devices not recognized.

So I used a Windows PC, but it is not recognized either.

Do I need to install a special driver to recognize the Uart serial?

Or is there a problem with the Jumper setting?

    Hello,

    I set the jumpers same (JP1 removed, JP4[2-3], JP5[2-3]). However, when I connect the USB cable from CN4(ST-Link V2-1) to PC, the results are still same as yours. (Linux host pc: /dev/ttyACM* devices not recognized. Windows PC: the USB is not recognized either.) Do I need any other driver or accessory for this?

    Thanks.

    Hi,

    what is the status of LD6 ?

    Check your USB cable, there is some USB cables (provided with cheap gadgets) which does not have USB data connected (only VBUS wires) !

    Hi,

    LD6 is off.

    I tried other 3 USB cables. They are all the same.

    Thanks.
