Kernel settings required for alsa/sound:

Kernel settings required for AX88179 USB ethernet:

I'm having trouble getting my kernel to give me any graphics. Can you post your kernel config? What kernel version are you using?

ASM / Re: Interrupt question
« on: April 07, 2018, 12:02:36 am »
I believe there is a way to set an interrupt on a certain number of cpu cycles having elapsed. I haven't ever used it, though.
From what I understand about the timers, you could set the counter to 15, and the on/off port to 0x80 to get interrupts every 15 ticks.

Did you happen to take a picture or remember which trace it was on? I'm not how useful that information would bee, but it might be interesting.

Not to hijack this thread, but I guess I'm also kinda back?
same, basically. I'm more on IRC, but if I see a good topic, I'll try to reply. I might even make my own!

HP Calculators / Re: HP Prime Emulator

We're emulating at a level much lower than the syscall level, we're emulating the hardware the syscalls run on.

HP Calculators / Prime Linux
« on: August 30, 2017, 11:21:00 pm »
Linux is coming to the Prime.
It should have been there a long time; the chip it runs on, the S3C2416, has been supported for a long time. Recently gaining access to tools for jtag, I decided I would go and connect things up, not realizing that the newer revision of Prime didn't even have jatag pins broken out on the front of the board. I bought a prime, and started working.

Tonight, I got up and running with a shell. There's nothing else here but the shell, actually, and many things don't work. But I got the LCD and serial port working, which is easily enough to test with.

Here's a picture of the shell up and running on tty0:

The sources can be found on my github:
ripem build with loader
qemu for Prime
Since I don't have a good setup for the initramfs running right now, I'm going to figure out how to get buildroot up and running. As long as I'm not too busy with school, I'll figure out how to make a keyboard driver and get the rest of the theoretically working platform drivers (usb, touchscreen) working. If anyone wants to help, go ahead!

x-posting to Cemetech and CW

Ah, good to know. I have been using it and fixing some things on the emulator, and my branch I think does interrupts well enough to run the OS. I'm not sure how exactly the rest of the OS is loaded.
I hadn't been using the -kernel option, but I'll definitely start.

Is there a way to get past the 1Mb limit in PRIME_OS.ROM? I have a project which would really stand some more code space.

I am glad to see Prime dev going on! I have just ordered a prime, and have the tools for jtagging. Once I get the prime, I'll have a look at stuff, and can maybe help get more things done.

General Calculator Help / Re: weird i/o port behaviour on ti-92
« on: May 23, 2017, 11:19:59 am »
If the I/O port is picky, it's possible that there's a bad connection in the I/O port, which would explain the problems you're having.

How long ago did it work? The silverlinks sometimes (theoretically at least) have problems where they just go bad after a while.

This is cool. I especially like the one with the moon (earth? other sphere?) rising in the distance and the fractally one.

What kind of modifications are you making? What kind of modifications are you making, and what software are you using to make them?

TI-Nspire / Re: Peripheral Not Identified

The issue is cropping up before he even get's to the Nspire step, that's not it (yet).
Ah okay, nevermind then.
I'd recommend using a non-virtual linux box to work with, if you can figure out a way to do that, or maybe a linux with a flash drive root (you can do that with debootstrap too!). Virtualbox usually works, but I've seen weirdnesses with USB forwarding which might be causing problems.

Sometimes the flash drive draws too much power. If you have a powered hub with a mini-USB port, you can use the link cable that comes with the calc to avoid any problems, and also plug in a real keyboard.

Computer Programming / Re: Standart game data folder on Linux/ OsX?
« on: January 03, 2016, 03:06:09 pm »
~/games means (user's home dir)/games, which would normally look like /home/username/games

I have more often seen game data in ~/.local/share/$programname
according to, programs should use $XDG_DATA_HOME if it is set, or if it is not set, use ~/.local/share/programname
