| |
| The port based upon an early (partial complete) |
| armboot-port from Stephan Linz for the ModNET50 Board. |
| |
| |
| Overview: |
| |
| - board with Netsilicon NET+50 ARM7TDMI CPU without MMU |
| - 16 MB SDRAM |
| - 2 MB Flash (MBL29LV160BE) |
| - 10/100 Ethernet PHY (LXT971A) |
| |
| |
| Current Configuration (include/configs/modnet50.h): |
| |
| Memory Map: 0x00000000 - 0x00FFFFFF 16M SDRAM |
| 0x10000000 - 0x101FFFFF 2M Flash |
| |
| The Flash uses a BB-Architectur with 35 sectors |
| (0:16K; 1,2:8K; 3:32K; 4-34:64K). U-Boot is located in |
| the first 5 sectors. |
| |
| The environment is located at the end of the 4th Flash |
| sector (0x1001C000-0x1001FFFF). |
| |
| Build: |
| |
| U-boot should be build by using the ELDK Toolchain (arm-linux-*). |
| |
| make modnet50_config |
| make |
| |
| |
| Status: |
| |
| Everything seems to work fine. Booting images was tested by |
| booting uCLinux (with and without a separate ramdisk image) from |
| flash. |
