The newer version is a total rewrite of the original code to switch to device trees and has slightly less hardware support (but better USB support). There have also been successes running Arch Linux for ARM and Debian. You may also need to add rootdelay=10 to give the USB drive time to initialize. Otherwise, there are a few on the nightly builds page and the Omnimaga thread.įor a larger root filesystem, you could put a filesystem on a USB drive and add root=/dev/sdaX to your kernel command line. It is possible to build one using Buildroot. To have programs actually run on the kernel, you need a root filesystem of some sort containing the userspace programs.įor testing and mucking around, a initrd should be enough. Check the nightly builds for example configs you can use.Ĭp -v arch/arm/boot/dts/nspire-*.dtb /path/to/folder/ Unfortunately, the newer kernel does not have a defconfig at the moment.
To compile the legacy kernel with default options, first clone the github repo then run:Ĭp -v arch/arm/boot/zImage /path/to/folder/zImage.tns Please see below sections for the differences between the legacy and newer kernels. Remember to add ,115200n8 to the end of your console= command line options to keep the baud rate the same as the Nspire OS. To boot the device tree (newer) kernel, ensure you add a dtb command to load the correct device tree prior to booting. This should save a lot of typing everytime you need to boot Linux. Then simply open your script file and the loader will execute all the commands ll2.tns, and add theįollowing line to your /documents/ndless/ file. Create a text file containing a list ofĬommands to be executed and change the extension to. Peek : Read a word from an arbitrary location in the memory address Poke : Write a word to an arbitrary location in the memory Supported by the bootloader, you can use this to try and guess how much memory Probemem: If this is run on an calculator model that isn't directly Rdsize : Get/set the size of the ramdisk that Linux should create onīoot. Useful for overriding the builtin default value without having to recompile. Phys : Get/set the address and size of physical memory. Useful for overriding the builtin default value without having to Mach : Get/set the machine ID that will be provided to Linux uponīooting. The Nspire OS and amounts used by the kernel and ramdisks.Ĭmdline : Get/set the kernel command line parameters. Useful forįree: Prints out the total amount of memory provided to the bootloader by
Kernel : Loads a kernel image into memoryĭump: Prints out the current internal state of the bootloader. Usage instructions can be found in the readme Copy linuxloader.tns to your calculator and run it. The bootloader is run from the Nspire OS to load everything into memory and execute the kernel. To have something useful running using Linux on the calculator, a bootloader, kernel and rootfs is needed.
