How to get terminal on STM32MP157D-EV1? The COM port cann't be seen from the host PC.

[HKim.23]

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?

Oh ~~~~~~~~~ Sorry,,,

JP1 must be removed.

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.
