Ways to boot the Clusterboard
#1
Hi,

even though the sopine64 module itself supports PXE boot I read some post that u cant PXE boot all the boards on a clusterboard. Currently you can only boot up to 6 sopines from the 7th.

Another ways is having your independet Linux on each Sopine and update them manually or by some tools like cssh or writing your own scripts..


Am I missing something?

Greetings,
Khaosgrille

I realize this is an old post, but assuming your clusterboard is connected to your network and you have a separate PXE server, why would you not be able to boot all 7 of your SOPINEs from the external PXE server?

Wait, what... you can boot 6 of the sopines from the 7th? How? I'm more than happy to have six of them boot from the 7th, with the 7th acting as an orchestrator / manager for the other 6. I'm presuming you mean the primary one is the one which has the eMMC module?

@jbobspants: I'm guessing they're not being booting by PXE, as AFAIK, PXE networking wasn't working properly with the custerboard - but perhaps that is only for interfacing with anything beyond the switch in uboot... hm... food for thought!

Oh, from the wording of the first post, I just assumed he was talking about PXE booting 6 of the modules from a PXE server running on the 7th module. I read that ayufan had implemented a PXE boot loader that could be installed on the SPI flash, but considering I'm having issues getting ANY networking to work properly on my clusterboard, I hadn't even started looking into that option.

Yeah, that's what I was thinking as well, which would be a marked improvement on the state of affairs when I tried it last, and couldn't get any of the them to PXE boot off a external PXE server... and since my intention for them to be run in a cluster, with the primary node being the orchestrator for them, the booting of 6 off the one (with eMMC) would be just fine...

Would just be nice if there was some (even dot-pointed) documentation to indicate if this works, any workarounds that needed to be implmentnted, and limitations/quirks. i.e. Do you have to fully boot the first module up, and then reset all the others? Or do they hang-around and retry for long enough for it to boot and announce? Was this with a patched uboot? mainline kernel? etc.

Sorry for the long pause.

I just read somewhere that it is supposed to be possible to boot 6 boards from the 7nth.

Right now i am thinking about giving https://www.barebox.org/ a try. It seems to be more versitaile than u boot and maybe i can do more with it.
