Design specifics:
|
| 6 |
|
|
|
| 7 |
|
|
* System reset is mapped to the SW[4]
|
| 8 |
|
|
|
| 9 |
|
|
* The console UART (UART 1) is connected to the P3 DB-9 connector.
|
| 10 |
|
|
|
| 11 |
|
|
* The JTAG DSU interface is enabled and works well with
|
| 12 |
|
|
GRMON and Xilinx parallel cabel III or IV .
|
| 13 |
|
|
|
| 14 |
|
|
* The GRETH core is enabled and runs without problems at 100 Mbit.
|
| 15 |
|
|
Ethernet debug link is enabled, default IP is 192.168.0.51.
|
| 16 |
|
|
|
| 17 |
|
|
* The SRAM (1 Mbyte) is attached using a modified version
|
| 18 |
|
|
of the leon2 memory controller (mctrl_avnet). This is
|
| 19 |
|
|
because the address bus is work based rather than byte based
|
| 20 |
|
|
and needs to be shifted 2 steps. It is possible to start
|
| 21 |
|
|
grmon with -normw for better performance. The byte-enable
|
| 22 |
|
|
strobes for the sram are connected and read-modify-write
|
| 23 |
|
|
is not needed.
|
| 24 |
|
|
|
| 25 |
|
|
* The Avnet flash/sram/sdram mezzanine (ADS-FLASH-DAU-G) is
|
| 26 |
|
|
supported. It provides 16 Mbyte flash and 1 Mbyte additional
|
| 27 |
|
|
sram. The sdram is attached but does not work - if somebody
|
| 28 |
|
|
can fix this then let me know. The FLASH memory can be
|
| 29 |
|
|
programmed using GRMON.
|
| 30 |
|
|
|
| 31 |
|
|
* The LEON3 processor can run up to 40 - 50 MHz on the board
|
| 32 |
|
|
in the typical configuartion.
|
| 33 |
|
|
|
| 34 |
|
|
|
| 35 |
|
|
* Sample output from GRMON info sys is:
|
| 36 |
|
|
|
| 37 |
|
|
$ grmon -eth -u -normw
|
| 38 |
