thank you, I have already opened a ticket and I didn't get a useful response until now, I need Udoo quad for my academic research
That's nobleness from you Andrea Rovai 1) sudden freezing issue during downloading or using USB memory card, that's an adapter problem for sure, (practically confirmed) 2) system doesn't start, that's an Yesterday (17-1-2016), freezing got back to me again even with 12V (5A) AC-DC adopter and good powered screen especially when I did any downloading/copying. However when I returned to 12V(2A), ALL sudden freezes disappeared. Current Conclusion: Frequent screen freezes that I faced, have nothing to do with UDOO operation software. It's size/kind/smooth power problem that responsible to run the device.
Pretty sure my UDOO Quad is a brick, but I am hoping it will come back to me. I just set my UDOO back up. When I plug it in it does not boot. The led comes on and is a steady green, but I get no output on the screen. I plugged CN6 into my Linux PC for serial debugging and dmesg does not show "usb 2-2.1: cp21x converter now attached to tty" or anything close to that. I am using a 12V 2A power supply and have even tested with a 12V 3A power supply. I have tried 3 different SD cards and a bunch of different images. I have flashed them using Linux and Windows and run checks on all three cards. I cannot find anything wrong with them. Is there any recommended steps for troubleshooting this? I opened a trouble ticket already.
Have you seen this http://www.udoo.org/docs/Troubleshooting/Why_My_UDOO_Wont_Boot.html If you have no screen output can you connect your Udoo with a network and see if it is accessible over the network with a browser or with vncviewer. The latest udoobuntu 2 has a webserver and xvnc server running so you should be able to access it through its IP address. If that works you have a display (cable) error.
Yep followed that doc. I also tried multiple different known working HDMI cords. I also checked my router to see if it was pulling an address via DHCP and it was not.
I am working with my Udoo neo board. I am seeing the same behaviour of board. 1. I have setup serial connections on UART1_Tx/UART1_Rx according to pinout given in following link, http://www.udoo.org/docs-neo/Hardware_&_Accessories/UART_serial_ports.html I have connected Ground pin to one marked on the board. 2. I use a 12V, 1.5A adapter to power the board 3. Serial console setup follows steps given in following link, http://www.udoo.org/docs-neo/Basic_Setup/Serial_Debug_Console.html 4. I downloaded uboot-imx/ sources, build SPL, u-boot.img with udoo_neo_config and prepared SD card as given in github README.md section "SD Card flashing", https://github.com/UDOOboard/uboot-imx 5. U-boot booted successfully and I have been using this method to work from past couple of weeks. Today, I see the u-boot does not come up and the board, though powered ON with solid green power LED, does not boot with same method. 6. Just to be sure, I downloaded the UDOObuntu 2.1 Minimal (14.04 LTS) image file from http://www.udoo.org/downloads/ and prepared two SD cards with instructions from http://www.udoo.org/getting-started/creating-a-bootable-micro-sd-card-from-image/ and checked, the board turns ON with solid Green LED but does not show any messages on the console when I tried with both cards. Please help.
Be aware that you have to download Udoo Neo images and instructions. You are referring to old Udoo dual/quad documentation. The correct documentation is http://www.udoo.org/docs-neo/Getting_Started/Create_a_bootable_MicroSD_card_for_UDOO_Neo.html The image file you have downloaded should have the name neo in it (eg udoobuntu-udoo-neo-minimal_2.1.zip) If everything still fails to boot it looks like you have to open a support ticket as it seems that you have a hardware failure: http://www.udoo.org/customer-care/
