| This leon3 design is tailored to the Digilent Spartan3-1600E Evaluation board: | ||||
| http://www.digilentinc.com/Products/Detail.cfm?Prod=S3E1600&Nav1=Products&Nav2=Programmable | ||||
| Design specifics: | ||||
| * System reset is mapped to SW_SOUTH (reset) | ||||
| * DSU break is mapped to SW_EAST | ||||
| * LED 0/1 indicates console UART RX and TX activity. | ||||
| * LED 2/3 indicates DSU UART RX and TX activity. | ||||
| * LED 4 indicates processor in debug mode | ||||
| * LED 7 indicates processor in error mode | ||||
| * The GRETH core is enabled and runs without problems at 100 Mbit. | ||||
| Ethernet debug link is enabled, default IP is 192.168.0.51. | ||||
| * 16-bit flash prom can be read at address 0. It can be programmed | ||||
| with GRMON version 1.1.16 or later. | ||||
| * DDR is mapped at address 0x40000000 (64 Mbyte) and is clocked | ||||
| at 100 MHz. The processor and AMBA system runs on a different | ||||
| clock, and can typically reach 40 MHz. The processor clock | ||||
| is generated from the 50 MHz clock oscillator, scaled with the | ||||
| DCM factors (4/5) in xconfig. | ||||
| * The APBPS2 PS/2 core is attached to the PS/2 connector | ||||
| * The SVGA frame buffer runs fine with 800x600 resolution. Due to the | ||||
| limited number of clock buffers, no other resoltion is supported. | ||||
| Note that the board does not have a video DAC, so only the MSB bit (7) | ||||
| of the three colour channels is connected to the VGA connector. | ||||
| A test patter can be generated using grmon-1.1.18 or later with: | ||||
| draw test_screen 800 16 | ||||
| * The DSU uart is connected to the female RS232 connected. | ||||
| The application UART1 is connected to the male RS232 connector. | ||||
| * The JTAG DSU interface is enabled. | ||||
| * Output from GRMON info sys is: | ||||
| ethernet startup. | ||||
