Hi, don’t mean to necro an old post, but am still exactly on topic: kano on raspberry pi zero w.
I’m in the same boat, trying to get my pi0-W working with kano. So far looking fairly bleak, especially since mine is the W(ireless), not just the zero.
Been snooping around for a couple of days. It looks like they had some versions (up to 3.7, judging from youtube vids) working on the zero (not w). Now Kano seems to have completely dropped any mention of zero (original or w) on their official site. The site only offers version 3.14 for pi 2 & 3, and ver 2.1 for the pi 1. Neither works on the zero w: 3.14 hangs at rainbow screen (fails to load kernel?) and the 2.1 hangs at black screen.
I wanted to find any additional kano os kanux images, but all my searching turned up was this resource: http://dev.kano.me/public/
It does have ver. 2.2, one for the zero (with “PiZero” in the name) and one general. Both throw 2 errors on boot:
[ 0.127589] of_platfrom_populate failed: -22
[ 0199426] bcm2708-dmaengine bcm2708-dmaengine: failed to get irq for DMA channel 13
Both installs DO get past these errors and boot on my zero w, but wifi and bt are dead. Overall experience with either is slow and graphix are blurry. Couldn’t find a set of settings a la raspi-config to change much in settings that made things better (but I haven’t tinkered with it enough). The non-zero 2.2 image seems to work better (although as I write this I cannot remember specific behaviors that distinguished them off the top of my head).
The http://dev.kano.me/public/ site also has US english images going back to 3.10. Although I expected 3.10 to work as one youtuber referenced it as a zero compatible version, it also just hangs at the rainbow screen.
So, a version of Kano can work on the zero w! It would be nice to try other versions that seem to have worked on the original zero, as reported by youtubers and others, like kanux ver 3.4 and 3.7.
Although 2.2 works, I can’t give it version to my kids as is, at least until I can clean up the looks.
Then it would also be nice to avoid the errors that pop up. And add wifi… Theoretically it’s the same chip wifi/bt as the pi 3, so it should be already built it to kano.
So, if anyone has any relevant insights, please share! Specifically, I’d greatly appreciate pointers on these questions:
- where can kano ver 3.4 - 3.7 be downloaded? could any kano owners share theirs?
- any ideas on the errors that 2.2 throws:
[ 0.127589] of_platfrom_populate failed: -22
[ 0199426] bcm2708-dmaengine bcm2708-dmaengine: failed to get irq for DMA channel 13
- any chance I could add or activate wifi/bt driver for the zero w’s built in chip in 2.2?
WIth zero w’s becoming more widely available, I would imagine and hope more of us cheapskate parents would get on this to make it work
