1. Select 'Power Target' in 'AVR Pocket Programmer'.
2. git clone https://github.com/arunkumarv31/rtos
3. cd compile 
4. Edit Makefile. Comment avrdude line with option arduino and uncomment line with option usbtiny in burn section.
5. make
6. sudo make burn
7. sudo (or be root) is mandatory. Because linux may not show error as permission denied, instead it will show initialization failed, rc=-1. 

If you have your own code and hex file. Burn the hex with this command -

• sudo avrdude -F -V -c usbtiny -p atmega328p -D -b 115200 -U flash:w:main.hex 

This same procedure can be used with other boards.

For Arduino mega2560 sudo avrdude -F -V -c usbtiny -p atmega2560 -D -b 115200 -U flash:w:main.hex 

Edit inc/common.h and Makefile in rtos if you are using my codes.
