Customization of GPRS, and Wi-Fi device drivers for PXA270 of Linux OS based barcode scanner

To access any device, it is necessary to have an point. A device driver entry point a device. This project aimed customize the Wi-Fi and general packet radio service (GPRS) drivers in Linux OS for PXA270 (Intel Xscale ARM processor). Customizing special way of designing software that can be more easily ported from one architecture another without rewriting scratch. The paper discussing about customisation GPRS develop driver, understand processor kernel internals other design constraints. Since dynamically loaded module attached existing kernel, error will crash entire system. Resource allocation implementation main concerns developers. resources are input/output, memory, IRQs ports. required toolchain build cross-complier Intel was built on platform. customised Wi-Fi, customised, images made port EMX-270 board. With all supporting parameters with efficiently. Also, successful verification testing had been performed their functionalities.
