## How to use
|
|
This repository contains a prebuilt version of qloader2 so building it won't
|
|
be necessary.
|
|
|
|
In order to install qloader2 on a MBR device (which can just be a raw image file),
|
|
run the provided `qloader2-install` script as such:
|
|
|
|
```bash
|
|
./qloader2-install ./qloader2.bin <path to device/image>
|
|
```
|
|
|
|
If using a GPT formatted device, it will be necessary to create an extra partition
|
|
(of at least 32K in size) to store stage 2 code. Then it will be necessary to tell
|
|
the install script where this partition is located by specifying the start sector.
|
|
|
|
```bash
|
|
fdisk <device> # Create bootloader partition using your favourite method
|
|
./qloader2-install ./qloader2.bin <path to device/image> <start sector of boot partition>
|
|
```
|
|
|
|
Then make sure the device/image contains at least 1 partition formatted in
|
|
a supported filesystem containing a `/qloader2.cfg` or `/boot/qloader2.cfg` file
|
|
and the kernel/modules one wants to load.
|
|
|
|
An example `qloader2.cfg` file can be found in `test/qloader2.cfg`.
|
|
|
|
More info on the format of `qloader2.cfg` can be found in `CONFIG.md`.
|
|
|
|
For example, to create an empty image file of 64MiB in size, 1 echfs partition
|
|
on the image spanning the whole device, format it, copy the relevant files over,
|
|
and install qloader2, one can do:
|
|
|
|
```bash
|
|
dd if=/dev/zero bs=1M count=0 seek=64 of=test.img
|
|
parted -s test.img mklabel msdos
|
|
parted -s test.img mkpart primary 1 100%
|
|
echfs-utils -m -p0 test.img quick-format 32768
|
|
echfs-utils -m -p0 test.img import path/to/qloader2.cfg qloader2.cfg
|
|
echfs-utils -m -p0 test.img import path/to/kernel.elf kernel.elf
|
|
echfs-utils -m -p0 test.img import <path to file> <path in image>
|
|
...
|
|
./qloader2-install $THIS_REPO/qloader2.bin test.img
|
|
|
|
```
|
|
|
|
One can get `echfs-utils` by installing https://github.com/qword-os/echfs.
|
|
|
|
## Building from source
|
|
In order to hack qloader2, one must build the GCC toolchain from source first.
|
|
|
|
To do so, run the `make_toolchain.sh` script from within the `toolchain` directory;
|
|
keep in mind that the script takes `MAKEFLAGS` as an argument.
|
|
|
|
```bash
|
|
cd toolchain
|
|
./make_toolchain.sh -j4
|
|
```
|
|
|
|
After that is done, simply run `make` in the root of the repo to generate
|
|
`src/qloader2.bin`.
