Re: uShell operating system kernel discussion

So if I understand, it's like the bootloader with a command shell that's always there? It programs whatever lower flash is left? Pretty much yeah. The kernel part is meant to remain end-software-indifferent so that you can write any kind of program that runs on top of it, as long as said program do...

Re: uShell operating system kernel discussion

Oh wow I didn't realize those are running from flash, but came from SD outside the ROM! This works in Uzem? Would cooperative multitasking(yield(), and honor system on RAM)be in the realm of reasonable? I actually completely forgot Uzem supports SPI RAM, I was under the impression that it didn't! :...

Re: uShell operating system kernel discussion

In the meantime, can you try the submode 6 and 7 examples here? https://github.com/Uzebox/uzebox/tree/master/kernel/videoMode748/examples If those examples work without issues then that indicates that it's an issue with my code rather than a hardware fault. It does seem my Uzenet adapter is faulty ...

Re: uShell operating system kernel discussion

Spectacular stuff, Uzebox Paint!! Haven't had a chance to try it yet but this is exciting. I scanned the code quick and I see it's not emulated. I wonder if a small VM written in AVR would allows running programs from SD, etc. A Telnet VM might even be good enough speed? Keyboard and mouse support ...

Re: uShell operating system kernel discussion

Got it to boot again and this time I had my mouse to hand. It seems the mouse only works in controller port 1. I clicked on DESKTOP.BIN but I got the error: Failed to open /ushell directory! Afte a few minutes or maybe up to 10, the text started to distort before disappearing completely. That error...

Re: uShell operating system kernel discussion

I tried ushell again this morning and I had it boot successfully once with no visible video/text issues on my first attempt. However, I didn't have my mouse or keyboard plugged in. By the time I had fetched them (less than 5 minutes later), the ushell text had disappeared and I just had an empty bl...

Re: uShell operating system kernel discussion

Very cool project ry and welcome to the forum mebibytedraco! I've tried this again since learning about having to copy the ushell dir and desktop.bin file over. I have seen it print some text and I briefly saw the cursor too but the display wasn't stable. Thanks!! Does the display stability improve...

uShell operating system kernel discussion

This is uShell , a very work-in-progress "proper" operating system kernel for the Uzebox, utilizing Jubatian's video mode 748 (submode 7). It is meant to be an experiment to see how far I can drive the idea of turning the Uzebox game console into a general purpose computer. It is currently...

Re: mmc_lib vs Bootloader V5 vs PFF vs FatFS vs sdBase(sdSimple)

ushell builds now but I've not been able to get it to boot successfully. Do I need to do anything other than copy the ushell.uze onto my SD card? After loading ushell on my real Uzebox, the screen just blinks a couple of colours before the screen goes black. Does ushell require SPI RAM to run? I'd ...

You did say ushell is WIP, I know but here you go: ~/src/uzebox/demos/ushell$ make cd kernel-tools/bin/.. && make tools make[1]: Entering directory '/home/dan/src/uzebox/demos/ushell/kernel-tools' make[1]: *** No rule to make target 'tools'. Stop. make[1]: Leaving directory '/home/dan/src/u...
