I never was able to get the WAIT-mode power use down, perhaps due to the way multiple SAM3X power rails are tied together on the Udoo board. The...
Ah, interesting. I wonder if there's some unwanted pin-mux interaction between Ethernet MII signals and i.MX PWM, like what I just found between...
I had been noticing a ridiculous number of interrupts accumulating on IRQ 59 whenever there was traffic on I2C bus #1: # cat /proc/interrupts...
What do you mean by dirty? Full of analog noise? If you're checking it on an oscilloscope, is your probe grounded to the Udoo GND? Is the...
Try 'chmod +x devregs' after unzipping, in case the executable bit got reset by your unzip tool. If that doesn't help, there may be a...
Re: Sending Sensor Data Values from Arduino through Serial L SInce that sensor is an I2C device, unless you already have suitable Arduino code on...
Linux calls the first i.MX6 bus, the one appearing on pins 20,21 "bus 0" (/dev/i2c-0) even though it's labeled I2C1 in the pinmux definitions....
When connector CN6 is switched to the Arduino, the i.MX6's /dev/ttymxc3 interface conflicts with its transmit signal-- two RS-232 transmitters...
I think the Arduino/SAM3X erase jumper is actually J22 (behind main system power button). J16, near the two microUSB ports resets the SAM3X...
I have an application where I need to get the SAM3X Arduino CPU's power consumption down as low as possible (i.MX6 will be shut down for long...
I've noticed the real-time clock (RTC), the one which can be kept running without main power by connecting a 3V battery to J1, is wildly...
I found a couple of bugs in the mxc_spdif.c driver, where registers controlling two SPDIF flag bits were being incorrectly set. Until now I...
The small 'uboot' bootloader (similar to Grub or LILO on x86) normally has to be on an SD card, but can be configured so that everything from that...
I found at least one exception to all SAM3X pins coming up as input/high-impedance state by default, which instead gets forced hard-high (not just...
Based on the "Reset cause: POR" (meaning Power-On Reset), I would try swapping in another 12V supply if you can, if only to rule that out. Power...
You'll need two programs -- a very simple Arduino sketch to run on the SAM3X, reading desired analog pins with analogRead and reporting them with...
Yes, you can add a hub. The Udoo includes one integrated hub chip (Microchip USB2514) to fan out the i.MX6 CPU's main host controller to the...
I missed this before, but I think you have your shield over the wrong set of pins. It needs to be moved to the right by about 8 pin positions, or...
Andrea, I'd like to request that if you do switch to new forum software, please either import and convert all the existing posts and threads, or...
I think the magnetics are necessary for proper impedance-matching to the twisted-pair line as well as for surge protection -- attempting to wire...
Separate names with a comma.
