Neusoft PXA250/255 Development Board Based on Xscale Product Introduction

PXA250/255 development board based on Xscale is a PXA250/255 software and hardware design solution based on Embedded Linux. In order to help customers understanding the Intel Xscale processor structure, completing early project evaluation and developing system hardware and software, we provided rich hardware and software resources. Such as hardware plan, device driver source code, cross-compiling environment and Boot loader source code. These resources can greatly speed up the designing and development process by the hardware and software engineers. Customers can utilize the USB interface, Ethernet interface, PCMCIA, MMC, CF card interface, infrared interface, touch screen interface and other external interfaces on our board to evaluate and use as a reference in their design. Customers can also use these interfaces to develop their own solution. Synchronization problems of hardware and software development will be solved. Software developers can start implementation during the early stage of project. We also provide rich graphic user interface in the upper layer for the customers to use as reference in their development. Our solution is an excellent learning platform for the people who wish to learn Intel Xscale.
