Hi, My Ultra arrived today and its installed Windows 10 with no problems. I'm thinking out loud and never done any Arduino development but would it be feasible to put the board into standby and wake it up via the Arduino interface ? I was wondering if I could use an Particle Electron to control the state of the board. Is there any experts out there who could point me in the right direction ? I've written drivers before to do this via the USB interface using Human Device interface but that's the limit of my knowledge pretty much
I don't think people have gotten around to experiment with that much, but this was one of the advertised features. See Braswell Power Management From Arduino 101
Thanks @Maurice , I just started going through the documentation and found this which suggests the same: Thanks for the link, I'm going to study it now - lots to learn but it's cool stuff. I'll report back my findings here.
There is an option in the bios for enabling waking the board from the Curie. If you're having trouble getting this to work, make sure this bios option is enabled.
Currently this is not possible as UDOO has firmware bug which shuts down Arduino when UDOO goes into standby or other powersaving modes. UDOO team is working on releasing fixed firmware version.
OK, no I'm confused I put a circuit together as per the document and it did *seem* to work albeit not reliably e.g. it wouldn't always go into standby and then again it wouldn't restart all the time either. The problem is that I got some video it of it working occasionally but the update from @Markus Laire suggest this isn't possible so I'm not sure whats going on. @Markus Laire - Is there somewhere else I can read about the bug, is it being bug tracked somewhere ? We were hoping to use this board for a client project we have ongoing at the moment. All the best
See this picture https://www.udoo.org/forum/attachments/marvell_side1-jpg.700/ I use a Molex connector to bring out top-row of the 2x3 pin CN16 (ICSP) SPI connector. In my picture, brown wire goes thru a 2Kohm resistor to a LED and the orange wire connects to the other lead of the LED. (ignore the yellow and red wires) It is for me to verify if Arduino 101 is powered or not. P.S. current PC firmware/STM32 code is when Braswell is down or sleep, Arduino 101's power is cut off as well. ccs_hello
Here is the forum thread where Udoo team explained that Braswell power control through Arduino 101 is not working yet as advertised: https://www.udoo.org/forum/threads/arduino-power-on-in-s3-s4-s5-cpu-mode.6927/ Firmware update is on its way.
