  1. Just for anyone reading this, this might be related. Someone suggested prioritizing gzip in order to escape the slowness of LZ4 on ARM platforms. Here is the solution, which was also merged in Armbian itself:
  2. I just want to say, thanks for this. LZ4 was REALLY slow on my Renegade board, and it kept popping up. I added that line and did not touch any other file. Good to see it merged, too.
  3. Easiest way is to boot Armbian SD card and flash armbian to emmc from the board itself, honestly (It will show up as /dev/mmcblk0 - the one with the boot0 and boot1 sections) Librecomputer doesn't provide an easy external way to access the emmc. (Like SD adapter or something) I have noticed something very useful. If your u-boot supports it you can use ums command to get Renegade to act like a usb stick and access the emmc. But if you're asking how to flash, you'll probably be ok with the first option
  4. In light of a recent change of role for this Renegade board (It'll be a small headless server on a different location from me), I've switched it to Armbian! The changes I've made besides the usual config are: GPT (Not necessary: I just like the checksumming + backup partition table) and U-Boot switch to legacy channel because that channel has the ums U-Boot command. I figured Armbian would be less risky for stability, especially for kernel upgrades on a device I don't have physical access to. The armbian-config and relevant utilities are nice too.
  5. Yeah, I just like the Arch way of things. I started with Ubuntu like most people, and I do run Debian on one of the machines, but on my laptop I use Arch™ As for Debian being "better" I mean in the sense of "even being doable",. I brought the U-Boot upstreaming topic here because this distro does care to bring U-Boot and the like to more boards than other distros, especially ones that are not ARM-specific. As I mentioned, I didn't even know some defconfig for Renegade had been upstreamed! It was only Rock64 before, haha
  6. That's true, and I think Armbian is essentially the only way if you plan on using these boards' hardware, like hardware acceleration e.t.c. I do look around in the armbian build repo and there are always nice patches and fixes in the patch/ directory. I have SD cards with Armbian, Arch and other distros, and I only stick to Arch on headless because I'm less familiar with debian packaging. If I wanted to run anything more damanding than SMB or a torrent client I'm pretty sure Armbian is the only distro with support for these ARM boards' quirks. Generic distros like Debian, or Ubuntu or Arch are better suited for hardware with good upstream (Rockchip in this case) support
  7. There would be a lack of maintenance because 5.7 is not an lts version. 5.4 does exist though which is nice. Wait, why for 2 weeks? I was thinking I wouldn't be able to boot anything past 5.8.0.
  8. Armbian's kernels are fine! What I mean is that with the rockchip U-Boot I had before, I would not be able to run kernels past 5.8, at least on the distro I run on that card (Arch), which would be a problem for security in the future. I'd be stuck on 5.7 for example, with 5.10 being out... (e.t.c)
  9. Thinking longterm, I don't want to be stuck to legacy kernels. Of course I like the ums in the legacy uboot, it's just my solution for now
  10. Thanks. Well for my headless needs, performance is fine, so I'll keep the mainline U-Boot to boot Linux 5.8
  11. I definitely agree that it's not your concern if it's an Arch issue. I wanted to post because the whole mainline experiment with U-Boot. I really appreciate this project and its efforts with these funky Rockchip boards! So UMS is not an upstream thing? Is it that it needs a lot of board-specific patches?

  12. Thanks for the answer! Yes it would be awesome if UMS was enabled! cat: /sys/class/devfreq/dmc/trans_stat: No such file or directory Specifically, there is nothing under the devfreq directory. I'm running Linux 5.8 on ArchLinuxARM. The guys on the archlinuxARM forum are having (at least one of them) the same issue of getting stuck in "Starting kernel..." when using Rock64 and Linux 5.8, so it's not isolated to Renegade Maybe it has something to do with that distro's specific Linux 5.8 version?
  13. It seems the Linux kernel 5.8+ on aarch64 is incompatible with the U-Boot from 2017, at least on the RK3328 boards. This apparently affects the Rock64 as well as my own Renegade. Essentially U-Boot gets stuck on "Starting kernel..." In this post they fix it by recompiling u-boot, newer version from upstream In addition to the existing rock64 defconfig, it seems that the defconfig for the Renegade was finally upstreamed on May! No more 2017 U-Boot from rockchip for me, perharps... I modified for the renegade and actually got a system that can boot Linux 5.8. (flashed the loader1 and an .itb file) I have 2 (possibly 1) issue: 1) Like the current branch in the armbian build, uboot is missing the ums (USB mass storage) command which is really useful to modify the emmc from a pc. 2) The 2020 uboot i compiled shows DDR4 333 in the first stage, instead of the older DDR4 786Mhz. Does that mean the RAM gets initialized at a lower speed? Maybe, but at least I can boot newer kernels now. Also Maybe the Rock64 and Renegade armbian packages should actually use the upsteam uboot instead of rockchip's 2017 version. I don't know if you already do this in the build tools, but it would be cool!
  14. Have you tried the upstream kernel or are you using the vendor 4.4.something? Sorry if the question's been answered before
  15. I gotta be honest with you, I do like the finicking! Plus I'm tight on money. So I'll play around with uboot and its commands any day. I just found out that USB Mass Storage emulation works fine for playing around with the emmc from a PC! I never mentioned Armbian in my post. Armbian is very important and I'm thankful it exists. As far as I'm aware armbian is the only ready out-of-the-box experience for this board (the ones from Firefly are old and they crash a lot) I'm using an Armbian U-Boot with Archlinux on this board for months now. I was talking about Rockchip specifically. Armbian is a community distro
