strezh / autoload linux kernel module
Created December 20, 2016 11:01
Copy kernel module <module> to the drivers directory.
$ sudo cp <module>.ko /lib/modules/$(uname -r)/kernel/drivers/
Add the simple name of my module to the file /etc/modules. You can edit the file or just append to it as shown here.
$ echo '<module>' | sudo tee -a /etc/modules
Update the list of module dependencies.
$ sudo depmod
Reboot the computer and voila, it worked.

Automatic create /dev file when driver module is loaded, automatic load driver on startup.

Automatic create /dev file

example driver module:

#include <linux/kernel.h>
#include <linux/module.h>
#include <linux/init.h>
#include <linux/platform_device.h>
#include <linux/gpio.h>
#include <linux/fs.h>

Use STM32+CooCoX in VirtualBox VM on Linux
  1. Install VM Extension pack in Virtual Machine
  2. Enable USB2.0 (EHCI) Controller in VM Settings
  3. Start-up and and shutdown VM, to ensure VM installs driver required by USB2.0 Controller
  4. Add USB filter for ST-Link/V2 USB programmer. (Do enter serial number , VM has issue with serial number containing non-readable ascii characters. )
  5. Install ST-Link utility in VM.
  6. Plug-in ST-Link programmer. Note: Host may install driver for USB2.0 Controller. Apparently this only works on USB2.0 host port , but later versions of Virtual Box may support USB3.0 ports.

If you got error:

Could not load the Host USB Proxy Service

  1. Маленькая и удобная утилита для получения изображений с вебкамеры.
fswebcam -q -d /dev/video1 -r 800x600 /path/to/webcam.jpg
  1. Конвертирование y4m в различные форматы (вместо avconv может быть ffmpeg):
avconv -i <file_name>.y4m -pix_fmt yuv420p <file_name>.yuv
avconv -i <file_name>.y4m -pix_fmt yuv422p <file_name>.yuv
avconv -i <file_name>.y4m -pix_fmt yuv444p <file_name>.yuv

Установка под Linux

При установке под линукс (проверено на Ubuntu 16):

  1. Устанавливаем wine
  2. Из папки crack копируем файл MentorKG.exe в <install_dir>/linux (или /linux_x86_64)
  3. Выполняем
sudo chown root:root ~/.wine
