| U-BOOT Port for FSForth ModNET50 Board | |

| 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. | |
