Hello. I own a librem mini. After a while it becomes a bit annoying to manually go to and use the actual display and physical keyboard to confirm a new checksum on my /boot when i confirm the resigning of the boot partition. Having to physically get up and move to fix a system is weird.
I would like remote control for hopefully coreboot and definitely grub.
I am likely going to have another linux machine next to the librem mini, a router running dd-wrt.
I realize i can buy a network kvm and hook it up to the hdmi output, but it’s a bit expensive. There are also dedicated setups that forward hdmi over the network, but i think they require a receiver to use an actual hdmi port and do not send any protocol like vnc.
I noticed there are lots of features of coreboot for debugging output over usb, serial, etc. I also noticed lots of network features for the different librem dev kits. I don’t have a dev kit but i’m willing to buy a piece of hardware for this purpose if it’s not too expensive.
It looks like coreboot and grub seem to both support some kind of usb debugging cable interface.
Will these work for me if i get the right cable? Has anyone set this up? Are there any better ideas?
