IMPLEMENTATION OF LINUX BASED UART DEVICE DRIVER

Risma Rajan, V. Venkateswarlu

Abstract: This paper deals with design, implementation and testing of device driver for a DUART TL16C2550 peripheral on a MDROADM board. The MDROADM board is used in optical networks for switching the optical signals between the nodes. The MDROADM board is designed with a MPC8308 PowerQUICC II Pro Processor as the main processor and the TL16C2550 peripheral is used for extending the serial interface on the board. The MDROADM board runs an embedded Linux operating system. The device driver for the DUART TL16C2550 is designed based on the customized interfacing with the MPC8308 PowerQUICC II Pro Processor. The device driver is in compliance with Linux kernel V2.6.29.6

Keywords: Device Driver, Linux, embedded system, DUART, TL16C2550.
