@CHENGYU LEE  I have the iPi-SMARC - x86 no? Simply followed directions on your website for ubuntu.

The i2c_i801 driver is for the Intel based board, which board are you installing to?

@CHENGYU LEE  Thanks CHENGYU. Linux is one of my weaker points. Graham

The root password is probably not set - please login as a normal user, then do "sudo su" and change the root password (with the passwd command)

Hi Graham - what error messages do you see when trying to install? Maybe it's just a matter of editing /etc/apt/sources to include the right repository.

Hi Graham, can you try our Debian image or Yocto image, it has MRAA pre-installed already. Is "The linux pin numbers are reported invalid" an error message you see in the terminal? If yes, you mig...

@CHENGYU LEE  OK I see it now - I thought that was an ETH indicator LED. Do excuse me. Graham.

I-Pi can work with the following OS: 1. Yocto 2. Debian 10 3. Ubuntu 4. Android the links are shared in downloads and also there are guidelines for flashing the image to SD card 

@CHENGYU LEE  Thank you for that circuit. WE actually already have a rather elaborate circuit that caters for other contingencies too, such as intermittent power outages that leave the super...

  Mar 1   I just saw that Ubuntu & Yocto. Is it possible to provide Android?

@Mashi Tang  Hello, the LEC-PX30 that is used in the IPI-SMARC kits can support an eMMC. Starting with 8GB and more.

Hello, I notice that the SMARC module on our IPI-SMARC kits all have a non-populated eMMC footprint, is this device also available with eMMC flash ???

Hi Graham, Actually the HDMI display on the IPI is enabled through a DSI to HDMI bridge, so there is no EDID coming in to xrandr. You will most likely need to modify the kernel for this.

Hi Graham, there are several ways to do that. One way would be to use supercaps on the main 5Vdc input and use a GPIO to detect a low voltage.     There are several solutions already ...

@graham  Yes there is, this is located next to the Audio Jack. By default your I-Pi SMARC comes with RTC batt. installed, let us know if yours was missing!

How can the iPi be safely powered off without processor or SD card damage?

Is there an input for a battery to maintain the RTC?

How to use an 800 x 480 pixel (or other) display in ubuntu? xrandr edits do not seem to work

Hi. I installed mraa form https://docs.ipi.wiki/iot_pi/. The linux pin numbers are reported as invalid (234 - 262). What is correct?

We cannot install wxPython4 on Debian. One message stated that wx is not supported on this platform, yet https://packages.debian.org/hu/sid/arm64/python-wxgtkxx exists for this purpose. Also tried...
