News: Interfacing PCI-based peripherals to the Intel PXA27x
May 6, 2005 — by Henry Kingman — from the LinuxDevices Archive — viewsIn this technical whitepaper, Viosoft CEO Hieu Tran uses his company's debugging tools to explore QuickLogic's FPGA-based PCI bridge for Intel's PXA-27x, and an Atheros Wi-Fi card. He turns up an interesting attempt by Atheros to balance GPL compliance while protecting confidential third-party information.
The article outlines Tran's experience in setting up and using the QuickLogic PXA Wi-Fi daughter board to add a Atheros 802.11 A/G wireless card to Intel's PXA27x Mainstone evaluation board. By using a kernel debugger to set a few breakpoints in selected source files, he gathers some important clues about the operation of the bridge.
