UART and com-port proplem

Lars Greipl

Hello,

i want use the UART on the GPIO-pins. The driver for this is installed correctly. Both ports are activated in the BIOS.
But there is only one com-port in the device-manager , com1. It works, but on CN7.

I found this one

There is the solution to deactivate the debug-com-port, but I can't find this option in the BIOS...

Can someone help me??

Thanks!

Hi, larsmen

the BIOS menus are not available for 40-pin GPIO header (UART1), and it's for CN7
UP wiki <-- please refer to the UP wiki

Could you please provide me your BIOS Ver. ?

The BIOS is updated to UPC1BM0X_EFI, the latest to download.

Is there no way to use the uart1 as an COM-Port, like COM1?

Thank you!

From i know, you can't use directly UART1 in winodws , please use DIO SDK to controlling the gpio
