Thanks for the fonts, but it appears the fonts are already there, so how would I use them (e.g. how do I type the fontname, is it just the filename minus the .pcf.gz extention?)
I also saw a folder called "directfb examples" with some images. Is there a way to use the examples and/or view the images?

No. You're just installing fonts into your X. The images are unrelated to xterm.

To use the font you want, use xterm -fn name without .pcf.gz

Sorry, by "use" I meant open with some other program.

Is there a way to set which folder to use for fonts, whenever I use -fn [font name] it says "xterm cannot load font '[name]'". I used several different font names including: "4x6" and "4x6-ISO8859-1". The only exception is "6x13", which for some reason loaded fine.

Found blackbox, so now with it running in the background, all the X programs can fit in the window. Still would be nice to be able to us the smaller font. Would you happen to know where to find a 5x7 font?

If you open up this RPM in an archive manager you'll find a selection including 5x7

Where do I put the fonts and are there commands I need to run to set a font up, there is no mkfontdir and the fonts that exist (other that 6x13.pcf.gz) won't open.

How do I use the recent builds? I manage to run the first one with USB host function. But when I replace the zImage with one of the recent ones (tried expanded and defconfig), it gets suck after the "boot" line in the linuxloader. So I don't even get to connecting the rootfs. Is the bootscript still
Code: [Select]
kernel linux/zImage.tns
cmdline root=/dev/sda earlyprintk debug console=tty0 console=ttyAMA0,115200n8 rootdelay=10
boot
?

If you don't have mkfontdir, then you don't have the binaries necessary to do the more automatic font configuration. You'll have to build the font-utils tools from Xorg source, which I'm not going to help you with. Other people should be able to help, though.

I'm surprised it's not already in there. It's a standard part of xorg.

So have people managed to get a few Linux softwares to run and is there a compatibility list somewhere? For example, would TilEm, ZSnes and the like run (even if slower)?

@Naruto: Try doing the following:

1. Rename your "linux" folder to "linux old"
2. Create a new "linux" folder
3. Download all the files needed to run Linux (Do not use any of the ones you already have)
4. Place them in the new "linux" folder and try booting linux (use a initrd first to make sure it works)

This worked in my case.

@DJ zsnes will never run. It's half x86 assembly, and takes heavy advantage of x86 features that ARM doesn't have. You'd have much better luck by porting an ARM snes emulator.

The initrd works.
As I tried lauchning it using it using the latest rootfs, it displayed a lot more stuff than before. At the end it just repeated the line "can't run '/sbin/getty' no such file or directory", so I pressed the reset button. When the calculator reboots now, it just shows the loading screen background and the clock icon in the middle. I already tried accessing the service menu and doing a complete format. But after installing a new OS it still won't boot. What to do now?

There's a maintenance menu and a diagnostics menu. Which one did you boot to? Booting into diags and running the NAND tests has always worked for me.

Take out the battery, I've had to do that many times.

By rootfs do you mean the USB drive?
You may want to use the initrd and try to mount the USB flash drive in there, then use the device that works to boot (sda, sda1, ...) in your boot script.
Make sure to connect the OTG cable to the calculator before starting the bootloader.

Thanks, the calculator is booting again.

Yes, I mean the USB drive.
When booting the initrd, how do I mount the USB drive as rootfs? If I mount it normally, it doesn't work right.
I am using the same setup that I used for running the first version that supported USB host. That version still works. Only the new builds are causing problems.

When you plug in the USB does it come up with several debug messages.
To mount the flash drive type "mount /dev/[either sda or sda1] /mnt".
You can replace "/mnt" with an existing folder as the destination.
You should then be able to cd to the directory and view files.
What method are you currently using?
