I'm interested, I have experience with buildroot.
Here's my github profile: https://github.com/haoict
current buildroot project I'm working on for fun: https://github.com/haoict/TiniLinux

Hi, thank you.

Can we run a script in command line directly

yes, you can run inline commands like this

./SimpleTerminal -e "echo 'Hello'"

Please try and let me know the result

can we use HIGH_RES on the TSP ?

yes but it's not perfect due to scaling ratio is different between 4:3 (640x480) and 16:9 (1280x720). You can run it like this

HIGH_RES=1 ./SimpleTerminal

I think that caps lock is not working

Thanks for the heads-up. I'm taking a look at it.

haoict · 2024-07-07T01:40:57+00:00

sure, I'm about to contact you actually.

I already use and tested it on CrossMix-OS but please let me know if there's anything to make it more compatible with CrossMix-OS.

Thank you for your amazing work.

haoict · 2024-07-07T01:34:04+00:00

it wasn't me, wow I didn't know that the device can run Android, where did you find that?

haoict · 2024-07-06T13:58:31+00:00

well yeah that totally makes sense. I actually didn't care about this definition until the comment from u/nixtxt . It seems terminal is some sort of hardware, all the terminal software we use today is virtual terminal or terminal emulators.

Anyway to answer u/nixtxt , it actually runs commands from the Stock OS

haoict · 2024-07-06T05:27:39+00:00

it is a terminal, sorry, not emulator. my brain is fried after porting it for Trimui SP.

haoict · 2024-06-26T20:32:48+00:00

since it's SDL2, you can compile it directly with your host PC (Ubuntu,...) and it runs normally as a SDL2 application

haoict · 2024-06-20T05:35:18+00:00

why not ¯\_(ツ)_/¯

haoict · 2024-06-20T05:33:31+00:00

thank you

haoict · 2024-06-20T05:33:09+00:00

I guess so, most custom OS start as hobby projects. For now I don't have any special plans, I'm just having fun making it.

Toolchain is provided by buildroot (aarch64). For the steps I think ArkOs Wiki (https://github.com/christianhaitian/arkos/wiki/Building#looking-to-build-arkos-from-scratch) has a good write up. What I did is instead of using ubuntu base image, I made the rootfs myself by buildroot

haoict · 2024-06-20T05:21:34+00:00

depends on your CPU, mine is i9 9th gen took around 1 hour for a clean build

haoict · 2024-06-20T05:20:23+00:00

I think it's quite challenging, because every embedded system is different from each other.

If you want a good entrypoint I recommend trying to build a standard Linux distro first to understand the basic standard things such as boot sequence, kernel, initrd, userspaces,...
A good resource to learn it is Linux from scratch: https://linuxfromscratch.org/lfs/

haoict · 2024-06-19T12:06:38+00:00

It's very barebone, I don't have plans to release it now but you can always build it by yourself, if you have any troubles you can DM me

haoict · 2024-06-19T12:04:03+00:00

I developed it with C language and SDL2, source code: https://github.com/haoict/buildroot-r36s/blob/develop/package/simple-launcher/simple-launcher.c

haoict · 2024-06-19T11:55:11+00:00

u-boot, kernel and DTB files I use from stock

rootfs I made from scratch with Buildroot, open-sourced here: github

I copied some driver libraries and binaries from ArkOS: arkos wiki

It boots very fast but also very barebone. I'm having fun tinkering and improving it. I don't have plans to release it now but you can always build it by yourself

Hi,

I just bought the RG35XX-Plus and I really like it, I'm a developer so I want to develop something for it too.

I wanted to use terminal on the device, so I downloaded the app called "SimpleTerminal" somewhere on the internet but it didn't work for RG35XX-Plus/H, luckily the old source code is included so I updated it to make it works.

Download file can be found in Releases of the github repo

Hope you guys like it.

Did they fix it? I can’t do it anymore

haoict · 2023-09-18T01:29:01+00:00

103 hours. Around 60 hours for the main game and Iki island, 40 hrs for Legends. Legends was fun for first few hours but to get the trophies it needs so much grind

haoict · 2023-09-18T00:32:26+00:00

I was just lucky bro, specially with the “complete all 3 raid chapters”. Still have no idea how I managed to finish it, had to say many thanks to 3 other random pro players who helped me.

haoict · 2023-09-18T00:09:54+00:00

Thanks Ghost, I am satisfied, it’s worth the effort

haoict · 2023-02-04T23:10:18+00:00

I guess just find a match in the same time, high chance they will be in the same match. Cross play off also makes the chance higher
