802.11/Usage
v3 v4 42 42 43 43 The dual-processor architecture of the 802.11 Reference Design presents some challenges in debugging the software applications. 44 45 The usual debugging tools in the Xilinx SDK work fine with dual-processor designs. The Reference Design includes one instance of the mdm pcore. The mdm is connected to both MicroBlaze debug ports. The PC-side debug tools can connect to either MB via the mdm and xmd. 46 47 Each MicroBlaze processor has an xps_uartlite peripheral mapped to stdin/stdout. The WARP v3 hardware has only USB-UART transceiver. The Reference Design includes a uart_mux core which allows either xps_uartlite to connect to the USB-UART transceiver. By default the mux is controlled by the LSB of the user DIP switch on the WARP v3 board. A 0 (switch down) selects the UART for CPU Low.
