Hummingboard iMX6

Phishfry · Jul 29, 2016

I just discovered this board and see it is supported on FreeBSD.

How is it doing? Wiki says PCIe not supported, is that still the case?(Last edit Feb 2015)
Does the mSATA act right? Networking good?
I see the Edge model has M.2 SATA and PCIe with Sim slot.
Sounds nice. Not cheap.
Anybody using these?

I bit the bullet and bought a used i4Pro for 75 bucks. Will report back on the FreeBSD 11 experience.

Booted up and have an X desktop up and running with the scfb driver.
Next up MiniPCIe testing with an Atheros half card AR9380-AR5BHB112.....
HDMI works and networking seemed good.
sysutils/sysinfo only shows 2 cores, should be quad. Seems to be running slowly. Need to check CPU clock speed. Heatsink was hot after 4hrs.

No luck with the MiniPCIe slot. The mSATA on the bottom side does work. I used a 120GB module.
uBoot has to be on the microSD card to boot. Will not boot from mSATA.
gpio's are showing but 'unkown' status.

I can confirm the GPIO's are not working on this board. Spent the day on it. Works with Debian SD card not with FreeBSD.

gpioctl -lv shows 31 gpio pins available but no gpioled pins. I attached my test LED to pin 11+ and 9- ground. Pin 11 works as software pin 73 on Debian after exported. On and Off after setup as an ouptput worked as expected. On Debian bootup pin 11 defaults to an off state.

So no instructions for FreeBSD header pin to software pin assignments. On boot my LED test rig is lit. So I have 31 pins to try. I turn them all into output's and then set them all to a 0 and my LED is still lit. gpioctl -lv shows all my settings took. All outputs with value of zero.

So the board has 26 pins physically but 31 pins showing in gpioctl. So the board led's are not showing correctly as a gpioled type -as they are on the other ARM platforms. That would be my guess for some of the extra 5 pins gpioctl shows that are not on the header.

On my RPi2 gpioctl 35 1 turns on the red LED on board and gpioctl 47 1 turns on the green LED. They show up as gpioled0 and gpioled1 in gpioctl.

I was just messing with FreeBSD and Raspberry Pi2 as the GPIO pinout is the same as Hummingboard. On the Pi2 Header Pin 11 shows up as software pin 17 and works as expected.

This is what's going on there ...

It's the physical pin numbering versus the "BCM scheme".

Thanks for the info on the Hummingboard. I've looked at it in the past. It seems to have better memory options than the cheaper boards.
