Hey shepper, this is great, I've been thinking of working on this myself but it looks like you have more practical experience. One of the issues I had run into with the OEM software packages was no support for wired ethernet, my preference is wired connections for my devices. Looks like there was no way to provide driver support for different manufacturers. Using Armbian would remedy this. One of the hurdles I have found online involves the probe sensing that Sovol has used with this specific printer. They created a custom function (kx711) for their toolhead, that supposedly hasn't been merged with the mainline klipper branch. Don't know how difficult it would be to implement. Maybe I'll try going down this rabbit hole. Now that I see someone else is giving this a go I feel more motivated to do something too. If I can help let me know. My printer is the SV06 Ace Plus.

To anyone with and an mxq pro 4k v4.0 that has an eMCP memory module in it, If you ever you manage to soft brick your board to the point the maskrom button behind the AV port doesn't work here's the contact points for forcing it to enter maskrom mode. Note: After soldering to the pad indicated in the photo you can connect it to a 5V pad and do the same process and connect it to pc. Remove the connection once you detect that it entered maskrom mode (you might break the eMCP if you keep supplying 5V to it for a long time)

@Dangrain To flash in an eMCP board you can either use the Multiboot image or flash via rkdevtool in linux. eMCP is basically just emmc memory and ram packaged into one chip so the process is almost the same with emmc flash guide and Multiboot flash guide (sd card flash) PS: i have the same type of memory and almost manage to brick it (thankfully i managed to find the eMCP pads to force it to maskrom mode)

Hey friends, I'm back. Well, good news. I got the box to boot from an SD card, specifically the 'Armbian_23.08.0-trunk_Rk322x-box_buster_edge_6.5.5_minimal.img' image, bad news I am not sure how to get it onto the eMCP and this is probably not the way you're supposed to boot armbian. I got the rk322x-box.dtb from the 'LibreELEC-RK322X.arm-11.0-nightly-20240218-d7324fb-rk322x.img' image (used by KanexMarcus in the comment here) and I had to add 'irqpoll' to extraargs in armbianEnv.txt, only after that did it boot. Ethernet works, wireless doesn't, using lsblk doesn't display the internal storage. Not sure what to do now, just figured I'd check in just to tell everyone what's going on and how I got it working.

Hello, I had a similar problem - unbootable Rock64 after kernel upgrade from 6.6.x to 6.12.x (error: Wrong Ramdisk Image Format). You can look in this thread djurny found a solution, that works for me. Maybe it will help.
