Hi ESP_igrr, first of all I realized I did not mention I am running Linux Mint 19.1 in a VirtualBox VM. Sorry about that. I did not think this made a difference, as I saw the basic connection was working (JLink and usb2uart devices assigned to the virtual machine). Instead I had the chance to test o...
