You could still do things like overclock the processor too high or use bluescale too long.

Through accessing the filesystem ? . . .

Can system settings like contrast be modified directly by browsing through the file system or is that more internal stuff? If that stuff can be browsed and modified, I guess it could be changed, right? Keep in mind I have no tried your program yet and I am not experienced with Nspire ASM/C stuff, though.

The overclocking can be done by changing a value in RAM, and bluescale would be just like on the 8x calcs.

Bluescale can damage the screen, though.

My point exactly.

Define "bluescale", because I thought that was a test mode in the TI-83+/84+ LCD driver.

There was a topic on it. Basically, when you turn the LCD contrast up and down very fast, the screen turns blue.

Blue? The NSpire has no colours? Huh?

Read this. It was done on an 84SE, but really, it applies to all calcs. (Except for the Prizm, of course.)

I found a little issue with the sdk. In nspire-as and nspire-gcc, it's using the option -mcpu=arm7tdmi (likely a leftover from some GBA development software), but for the Nspire we need -mcpu=arm926ej-s. As a result, it wouldn't assemble some of my instructions. I've fixed this on my end, but it'll be good if there was a fix in the next release of Ndless

How did you get it to work? I tried it a while ago with ndless 1.0 and it made the calc crash.

All I did was replace the cpu type. What exactly were you trying to do that wasn't working?

I just replaced the CPU type too. I was compiling a C program with it. Tomorrow, I'll try it with ndless 1.7.

Oh, you meant that blue. I thought you meant test mode. We're not sure bluescale is possible on the Nspire. It doesn't even work on the regular 83+, just the 83+SE, 84+ and 84+SE.

I have just discovered that, while the Nspire's SRAM does repeat every 128KB at 0xA4000000, it is not actually 128KB of RAM. It is 64KB+16KB (the latter repeated 4 times for a total of 128KB address space). Meaning, there is only 80KB. Perhaps this might explain why Ndless always works on the emulator (which emulates 128KB RAM) and fails sometimes on hardware? I think I heard that Ndless installation messes with the SRAM.
