Sense-HAT on Pizero

[will.moindrot]

Hi everyone,

I was wondering if the Sense HAT is compatible with Pizero? I have got mine working well with my Pi2, however for a mobile project I was looking to use with my Pizero and I'm finding that the HAT is not being recognised. The LED matrix stays lit once the kernel loads and any quick test scripts produces the error: "cannot detect rpi-sense fb device"

• I have previously used a Pimoroni Scroll Phat display on the Pizero, through that enabling I2C.
• Since installing the Sense Hat on the Pizero I have followed the software installation guide here: https://www.raspberrypi.org/learning/ge ... /software/
  (going an apt-get install and upgrade, installing sense-hat and doing a pip install of pillow).
• After a reboot the led matrix stays on which differs to what I had previously seen on the Pi2
• Writing a quick python script to display some text on the display (following: https://www.raspberrypi.org/learning/ge ... worksheet/) and then running gives the error above "cannot detect rpi-sense fb device"
• I have tried to reseat the Sense Hat a couple of times but still no joy

The only thing I can think of (from my limited knowledge) that I haven't tried yet (damn day job!) is downloading a new copy of NOOBS to the SD card. But having said that I think I installed 10.5.0 when I got the Pizero last month. My Pi2's SD I think I installed Raspbian manually (not via NOOBS) so maybe that might be the problem?

Thanks, Will

I can't see why it wouldn't be. Mine is mounted on a B+ and I've seen one mounted on an A+.

As regards OS...I use a directly loaded copy of Raspbian Wheezy (which I'm keeping that way, as that is what is in use on the ISS).

It *should* be compatible.

Can you post the output of sudo vcdbg log msg? This will tell us if the firmware looked for a HAT EEPROM.

Hi Will

I had the same error message but

sudo rpi-update

followed by a reboot sorted it

Good luck

Thanks jdb, here's the info. I'll let you know if I get any joy in the meantime:

Hi 5uperdan,

That sounds about right - thanks for this. I have jumped the gun and just kicked off a reinstall of NOOBS (the same version as before though). So if it's still giving me trouble I'll try out the suggestions in yours and the thread you linked to. Thanks, Will

Hi Will

I had the same error message but

sudo rpi-update

followed by a reboot sorted it

Good luck

[5uperdan]

Seems my fix wasn't a fix at all and it was random luck that my sense hat worked for one boot and stopped working again after that. Think i might need to check my soldering work!

Is it coincidental that my sense hat seems to be recognised when i have a keyboard and mouse plugged in? Here is the log from a successful boot

Hi all, thanks to everybody who replied. Coming back to it this morning I managed to get it working on my Pizero:

Reinstalled Noobs 10.5.0, did apt-get upgrade and install, did rpi-update, and after reboot the matrix went off and could run my test program (found that did not have to install sense-hat or pillow as already there). So I think the rpi-update (that I think updates the firmware to newest version) did the trick.

Best, Will
