Zero USB booting

Just used rpiboot to get an Ultibo kernel.bin working on a Zero with no SDcard.
Used the standard start.elf and bootload.bin plus kernel.bin in the msd folder.

USB takes a bit of time to connect, so it is not as fast as normal <2 sec SDcard boot.
But this now means a Cluster hat of 4 Zero's and no SDcards needed for the Zero's?
Now network booting for the mother Pi3? 5 connected Pi's - no SD's :shock:

Rats, HDMI is same side as USB, else 5 HDMI outputs no SD, USB extension cables?
Need to get a few more Zero's, only got 4 but two are Zero W which I want to save for bots.
Time to start camping out on disty webshops.

That sounds like it could be interesting. I'm working on a cluster of four Zeroes, one of which has a HubPiWi attached to provide USB connections for the other three and WiFi for connection to the rest of the world.

I removed the USB sockets from the HubPiWi and ran thin cables for the data through the GPIO connector holes of each Zero and soldered them the the PP pads by the USB. I also soldered a couple of bits of solid core wire to connect together all the Pin 2 and also the Pin 6 of each Pi, so all I need to do is provide power to one of them. I just need to work on the software and networking now.

This makes it easy, hope the USB hub chip does not cause problems.

Noticed it on Pimoroni and got one with a Zero W to save some shipping pain.
