Hi list. For some time I have been struggling to get the serial console operational on an ASRock Q1900B-ITX mainboard (Intel J1900)
I have "-Dh" in /boot.config and tried enabling ttyu0 and ttyu1 in /etc/ttys. Serial cable was connected to the onboads serial ports of the mainboard. What I also tried was connecting the serial console cable to a USB to serial converter (using ttyU0 device in /etc/ttys), but also no luck. When I press return on an active console session the cursor on the console does a carriage return to the next line, but the screen shows no output at all. This can be seen on the USB to serial converter cable connection and also on the connection to the serial ports on the mainboard. I also made a test with kern.vty=vt console="comconsole vidconsole" comconsole_speed="9600" boot_multicons="YES" in /boot/loader.conf - but no solution. Is this ACPI related? Any hint appreciated. Regards, K. --- pciconf -lv --- % pciconf -lv hostb0@pci0:0:0:0: class=0x060000 card=0x0f311849 chip=0x0f008086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView SSA-CUnit' class = bridge subclass = HOST-PCI vgapci0@pci0:0:2:0: class=0x030000 card=0x0f311849 chip=0x0f318086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView Gen7' class = display subclass = VGA ahci0@pci0:0:19:0: class=0x010601 card=0x0f231849 chip=0x0f238086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView 6-Port SATA AHCI Controller' class = mass storage subclass = SATA xhci0@pci0:0:20:0: class=0x0c0330 card=0x0f351849 chip=0x0f358086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView USB xHCI Host Controller' class = serial bus subclass = USB none0@pci0:0:26:0: class=0x108000 card=0x0f181849 chip=0x0f188086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView SEC' class = encrypt/decrypt pcib1@pci0:0:28:0: class=0x060400 card=0x0f481849 chip=0x0f488086 rev=0x0c hdr=0x01 vendor = 'Intel Corporation' device = 'ValleyView PCI Express Root Port' class = bridge subclass = PCI-PCI pcib2@pci0:0:28:1: class=0x060400 card=0x0f4a1849 chip=0x0f4a8086 rev=0x0c hdr=0x01 vendor = 'Intel Corporation' device = 'ValleyView PCI Express Root Port' class = bridge subclass = PCI-PCI pcib3@pci0:0:28:2: class=0x060400 card=0x0f4c1849 chip=0x0f4c8086 rev=0x0c hdr=0x01 vendor = 'Intel Corporation' device = 'ValleyView PCI Express Root Port' class = bridge subclass = PCI-PCI pcib4@pci0:0:28:3: class=0x060400 card=0x0f4e1849 chip=0x0f4e8086 rev=0x0c hdr=0x01 vendor = 'Intel Corporation' device = 'ValleyView PCI Express Root Port' class = bridge subclass = PCI-PCI ehci0@pci0:0:29:0: class=0x0c0320 card=0x0f341849 chip=0x0f348086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView USB Enhanced Host Controller' class = serial bus subclass = USB isab0@pci0:0:31:0: class=0x060100 card=0x0f1c1849 chip=0x0f1c8086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView Power Control Unit' class = bridge subclass = PCI-ISA none1@pci0:0:31:3: class=0x0c0500 card=0x0f121849 chip=0x0f128086 rev=0x0c hdr=0x00 vendor = 'Intel Corporation' device = 'ValleyView SMBus Controller' class = serial bus subclass = SMBus re0@pci0:2:0:0: class=0x020000 card=0x81681849 chip=0x816810ec rev=0x11 hdr=0x00 vendor = 'Realtek Semiconductor Co., Ltd.' device = 'RTL8111/8168B PCI Express Gigabit Ethernet controller' class = network subclass = ethernet --- dmesg.out --- Copyright (c) 1992-2014 The FreeBSD Project.
