Here is a tutorial how to connect a serial console http://ch.ege.io/blog/2015/10/31/attaching-a-serial-console-to-udoo-neo/ Gesendet von meinem FP2 mit Tapatalk
Hey man thanks so much for helping. Now I'm able to play around with the board. Nevertheless I have another question. I would like to add some code into the u-boot. The reason that I need it into U-Boot is because I need that piece of code to be executed as soon as the board is plugged. So my question is, what should I do to add my code into the u-boot and then create the image again? Thanks!!
I need to add code to send some bytes to the LP5521 RGB LED driver chip. I have one that I have connected to the board and actually I'm currently using it from linux to indicate several statuses of my application but I need that the LED go RED as soon as I power the board and there is where u-boot enters the scene. Either by a u-boot script or C code is fine, I just have no idea what steps to follow to add this small piece of functionality to u-boot. Thanks!!
I'll try to write some howto when the Makerfair Bodensee is done. http://www.makerfairebodensee.com/ Gesendet von meinem FP2 mit Tapatalk
If you access lp5521 via i2c you may get some info here https://github.com/graugans/meta-udoo/wiki/UDOO-Neo Gesendet von meinem FP2 mit Tapatalk

Hi all, i make a try this evening to program the sam3x on udoo quad with arduino ide (from external pc). I follow the tutorial here but arduino ide don't find the device (i removed the jumper J18 and identified the port com before ). After that i tested this : http://www.udoo.org/docs/Arduino_DUE_(Sam3x)/Troubleshooting_Programming_Arduino_Due_from_External_PC.html but i have this error when i try to program the card with arduino ide (1.6.9 and 1.6.5) : SAM-BA operation failed ERASE FLASH An idea ?
This needs some investigation. UDOO Quad/Dual needs another tooling AFAIK something called bossac. And the arduino tooling may expects the UDOO to have a special IP or do you try over USB cable? Gesendet von meinem FP2 mit Tapatalk
Okay, looks like the Arduino GUI uses USB to serial in your case I'll check the schematic and try to find some time this afternoon to investigate it on my own. Gesendet von meinem FP2 mit Tapatalk
This morning i'm trying on another pc (under kubuntu 14.10) and i have this message on arduino ide 1.6.9 : /home/mls/.arduino15/packages/UDOO/tools/bossac-udoo/1.3a-1.0/bossac-udoo: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /home/mls/.arduino15/packages/UDOO/tools/bossac-udoo/1.3a-1.0/bossac-udoo)
Hi @graugans i have 2 anothers questions, i would like to add a ftp server on my image (for quad), i didn't find anything on it for the moment. Can you just confirm if i would like to add one i have just to add in my local.conf this for example : MACHINE_FEATURES_append = " \ lvds7 \ pure-ftpd \ " pure-ftpd is a part of meta-networking already use ... Another question, on my quad, i add a sata disk. I can saw it, mount it manually but if i would to mount it automatically at startup can you advise me a script or procedure please ? under a detail of my sdd : Disk /dev/sda: 232.9 GiB, 250059350016 bytes, 488397168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x00096d0b Device Boot Start End Sectors Size Id Type /dev/sda1 2048 488390655 488388608 232.9G 83 Linux
