Cheapest hardware for Dude Server

I have several hundred new Groove 52HPacn routers to deploy. I need to update the RouterOS and firmware on each of them, then install a standard config on them. I was thinking a Dude server would be helpful for this, but please tell me if I’m wrong about that. I thought if I connected a bunch of them to a lab network with a Dude server on it, I could use the Dude client to manage the updates and put configurations on them prior to deployment.

What is the cheapest hardware that will support a Dude server? I was hoping to run it on a spare Groove, but I see that that architecture is not supported.

Thanks

hEX + microSD is perfect

Ok, I didn’t think the Dude server would run on MIPSBE devices. If it will, then yes that would be a very cheap option, thank you.

no, it’s mmips not mipsbe

Ok, yes I see some of the hEX are mmips and others are mipsbe.

Thank you very much

CHR P1 as virtual machine?

P1 stays for what, please?
I do not understand, thanks

He means run a CHR, with license level P1
