Re: On the fly rereading config.txt

The CPU frequency is managed via Linux . http://www.mjmwired.net/kernel/Documentation/cpu-freq/governors.txt On the GPU , better ask dom. The memory can be dynamically managed , there is a config.txt option for it. AFAIK this feature is based on "CMA". This article might be useful for you : http://...

Oh, I am looking for the more GPU/CPU related options: memory management, clock speeds. Likely the user will want to have to change monitor settings once (in bootloader).

Re: Moving to larger SD

In windows use the Win32DiskImager that is used to flash the original sd card (download here: http://sourceforge.net/projects/win32diskimager/files/latest/download ) and select the read button with your old SD card selected as the device and the image file being where you want it saved to.

Re: On the fly rereading config.txt

AFAIK config.txt is just mostly kernel parameters, which you could pass to the kernel via kexec anyway... i.e. config.txt would load the kexec based bootloader, then you set more options via the bootloader when it boots the kernel again. I was playing around with the idea of a kexec based bootloade...

On the fly rereading config.txt

I'm attempting to build my own bootloader using kexec but would like to know how to reread config.txt without reboots. Maybe a stripped down start.elf? I would try but as far as Google knows there is no publicly available source code. Or, better, just a way to change config.txt properties (without c...

Re: Newbie C++ Compiler

Most Linux distros, like Raspbian, come with the GNU Compiler Collection. The C compiler is invoked on the command line with gcc, and the C++ compiler is invoked with g++. If learning C++, I recommend starting with some basic C. Read through "The C Programming Language" doing as many exercises asyo...

I may be 11 but I can build a minimal Linux system. Although the OP is crazy, I will try to help because it's pretty easy to find something better than OS X.

Re: Important notice for rpi public servers

I'm getting a 512MB SD Card with the boot partition on it. :mrgreen:

Then I will add USB HDD of some form with the OS. :mrgreen: :mrgreen:

Finally I will change config.txt to reflect the USB HDD. :mrgreen: :mrgreen: :mrgreen:

We mourn the death of a Pi accessory. Even though it failed at its task it did not deserve such a painful death. We bring flowers to show appreciation. I can't do it anymore. :cry:

Only by overriding or ignoring safeguards. You would experience other issues first but you could damage the processor. Otherwise, no. The worst thing to happen might be having to re-flash your SD card. Have fun! :lol: Hallelujah. I am only 11 and kind of have a habit of breaking things. Can't wait ...
