Hello. I have a Udoo Quad system which I'm trying to connect to via the Serial Console. I have followed the procedure for Linux at http://www.udoo.org/ProjectsAndTutorial ... ial-cable/ I have connected the USB cable (to the micro USB port closest to the corner). When I connect the USB cable to my Linux (RHEL) laptop I see: Code: Feb 19 14:46:10 rhel kernel: usb 1-1.1: new full speed USB device number 8 using ehci_hcd Feb 19 14:46:10 rhel kernel: usb 1-1.1: New USB device found, idVendor=10c4, idProduct=ea60 Feb 19 14:46:10 rhel kernel: usb 1-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Feb 19 14:46:10 rhel kernel: usb 1-1.1: Product: CP2104 USB to UART Bridge Controller Feb 19 14:46:10 rhel kernel: usb 1-1.1: Manufacturer: Silicon Labs Feb 19 14:46:10 rhel kernel: usb 1-1.1: SerialNumber: 0078AFFB Feb 19 14:46:10 rhel kernel: usb 1-1.1: configuration #1 chosen from 1 choice Feb 19 14:46:10 rhel kernel: cp210x 1-1.1:1.0: cp210x converter detected Feb 19 14:46:10 rhel kernel: usb 1-1.1: reset full speed USB device number 8 using ehci_hcd Feb 19 14:46:10 rhel kernel: usb 1-1.1: cp210x converter now attached to ttyUSB0 Feb 19 14:46:10 rhel modem-manager[2485]: <info> (ttyUSB0) opening serial port... ..... .....

Feb 19 14:46:23 rhelmodem-manager[2485]: <info> (ttyUSB0) serial port closed Then I install and configure minicom as recommended 115200 rate, no hardware/software flow control and device /dev/ttyUSB0. I start minicom and then power on my Udoo (Quad). My Udoo boots as normal. In the minicom window I hit some keys, but I never get any serial console. Note that my SD Card has installed the image "Ubuntu Studio 12.04 armHF". Hope that somebody can help! My intent was to get the system booting from the SATA drive. As I understood, this has to be all setup via the serial console (as you need to access uboot). Just to add, I've noticed in the boot-up messages the following: Code: Jan 1 00:00:06 udoo-studio-hfp kernel: [ 1.645646] imx-uart.0: ttymxc0 at MMIO 0x2020000 (irq = 58) is a IMX Jan 1 00:00:06 udoo-studio-hfp kernel: [ 1.646080] imx-uart.1: ttymxc1 at MMIO 0x21e8000 (irq = 59) is a IMX Jan 1 00:00:06 udoo-studio-hfp kernel: [ 1.711994] fb_videomode = 60 1280 1024 9259 248 48 38 1 112 3 3 0 32 Jan 1 00:00:06 udoo-studio-hfp kernel: [ 1.712008] fb_videomode = 60 1280 1024 9259 248 48 38 1 112 3 3 0 17 Jan 1 00:00:06 udoo-studio-hfp kernel: [ 1.763434] console [ttymxc1] enabled, bootconsole disabled Cheers, Slim
Howdy, does anyone have a suggestion for me to try? I'm not able to use a serial console from both Mac OS X and Linux to access my Udoo quad. -Slim
I DOnt have a linux workstation to do a test as i just use a windows box. Do you have the same issue when running the standard Linaro Ubuntu 12.04 LTS image From what i know it really shouldnt matter, but i have seen stranger things occur Sorry i cant provide more help, hopefully others can
Hi, just to understand your situation, witch OS did you used to read serial port (your host pc)? Are you sure the drivers are correctly installed? To verify if the UDOO Serial to USB Chip, remove J18 and try to program SAM3X microcontroller with patched Arduino IDE. (http://www.elinux.org/UDOO_programming_ ... controller) If it don't works there could be some problems with your serci chip. Regards
[SOLVED] UDOO Serial console does not work Problem solved now. Reinstalled the necessary serial driver on OS X and it all appears to be working now (the serial console). I'm now able to view and interrupt the boot process. Thanks for the input from all. -Slim
