| 7 | The port based upon an early (partial complete) |
| 8 | armboot-port from Stephan Linz for the ModNET50 Board. |
| 9 | |
| 10 | |
| 11 | Overview: |
| 12 | |
| 13 | - board with Netsilicon NET+50 ARM7TDMI CPU without MMU |
| 14 | - 16 MB SDRAM |
| 15 | - 2 MB Flash (MBL29LV160BE) |
| 16 | - 10/100 Ethernet PHY (LXT971A) |
| 17 | |
| 18 | |
| 19 | Current Configuration (include/configs/modnet50.h): |
| 20 | |
| 21 | Memory Map: 0x00000000 - 0x00FFFFFF 16M SDRAM |
| wdenk | f70cbb2 | 2004-02-23 20:48:38 +0000 | [diff] [blame] | 22 | 0x10000000 - 0x101FFFFF 2M Flash |
| wdenk | 2ebee31 | 2004-02-23 19:30:57 +0000 | [diff] [blame] | 23 | |
| 24 | The Flash uses a BB-Architectur with 35 sectors |
| 25 | (0:16K; 1,2:8K; 3:32K; 4-34:64K). U-Boot is located in |
| 26 | the first 5 sectors. |
| 27 | |
| 28 | The environment is located at the end of the 4th Flash |
| 29 | sector (0x1001C000-0x1001FFFF). |
| 30 | |
| 31 | Build: |
| 32 | |
| 33 | U-boot should be build by using the ELDK Toolchain (arm-linux-*). |
| 34 | |
| 35 | make modnet50_config |
| 36 | make |
| 37 | |
| 38 | |
| 39 | Status: |
| 40 | |
| 41 | Everything seems to work fine. Booting images was tested by |
| 42 | booting uCLinux (with and without a separate ramdisk image) from |
| 43 | flash. |
