🇵🇸My #riscv #tablet from #deepcomputing just arrived!
it is glorious chaos! I love it. But I also am a masochist when it comes to computers.
make of that what you will.
first thing: they ship ubuntu 24.04 but it is barely usable. htop shows gnome shell immediately maxing out one core every time you click on something. pretty brutal. opening an app takes about 5 minutes but will rather not work at all. glad I recently purchased a lot of sd cards. will OS shop a little I guess
boy oh boy. that was a tough day with #riscv and the #dcromapad2
turns out, both OSs (ubuntu and debian) that were shipped do work but they are so heavily patched that a simple upgrade will brick them.
ask me how I know! :D
the fact I made a copy of the sd card saved my day so I could at least use the tablet somewhat today.
deepcomputing is aware of the issue and provided a video and source for a new image. will attempt reflashing tomorrow. wish me luck.
let me know of any questiond! bye
Good morning! After a really short night, partly due to my new #riscv "toy" waiting for me, I'm back on #ubuntu 24.04 LTS. It's bumpy but what did I expect from a "dev" device.
I'm trying to look for information about how to make some actual progress. I checked flutter but the dependencies are not resolvable rn.
Anyone have an idea where to start with getting this device up to speed?
I totally forgot to send my last toot so now you get two at once!
I checked and found something rather unsettling: The #spacemit X60 core (seems to be part of the k1 processor) is marketed as RVA22 compliant but I dont think it is. So far, the following extensions do not seem to be included or I'm just blind: B, Za64rs, Zic64b, Zicbop, Ziccamoa, Ziccif, Zicclsm, Ziccrse.
There are a ton more extensions that are included and some that are optional so there is room for error on my side.
Here's the table I made. Feel free to point out mistakes. Source: https://github.com/riscv/riscv-profiles/blob/main/src/profiles.adoc#rva22u64-mandatory-base
poor brain. now that i am stuck for the moment in terms of debugging ubuntu and debian, I turned back to porting the device to #Postmarketos
this stuff is like drinking from a firehose. constant hyperfocus and breaks seem obsolete.
well, I'm meeting non tech friends later so thats gonna be my break then.
in the meantime #pmbootstrap fails to generate checksums for my apkbuild... probably because I am missing something with custom kernel...
Another day, another update on #riscv with the #dcromapad2
I have now again woken up much too early for a sunday because I cant let go of porting my device to postmarketOS.
I have now found a specific kernel for the spacemit k1 soc. I have no idea if this is gonna work but the chinese server I'm downloading it from is making it exciting with 135 KB/s!!!
Anyway, will update once I have news. :)
new update! good and bad news!
it only took a whole freaking day but I successfully built a postmarketOS image!
bad news: it doesnt boot, yet. reason being probably that the file structure or partition scheme are wrong.
i the community has been helpful too so thanks a lot so far! :) i hope I can boot this thing soon. that would be awesome
Hello world! I have news about the #dcromapad2
After successfully building a kernel and installing it to an sd card, the system didnt recognizes it. Turns out, the device runs uboot and needs a very specific card layout with 5-6 partitions it seems.
I frankensteined a copy of a copy of the shipped debian image to include the #postmarketOS kernel, initramfs and rootfs.
Now the device bootloops with no output until I rip out the card. Its a step, but a small one.
another update, but slightly different atm since progress has seized. no news on the broken boot image.
in the meantime - while taking a break - i played around with the frail ubuntu on the pad. its not unusable but the possibilities are VERY limited.
i wanted to install fluffychat, no install candidate, compile it, cant install toolchain, use web, wont load, try element, logs in but wont stop syncing. tried posting here, keyboard snaps to numbers only.
there is a LOT of work to be done.
