| 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 | |
| cd0a9de6 | 22 | 0x10000000 - 0x101FFFFF 2M Flash |
| 2d1a537d WD |
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. | |
