7 The port based upon an early (partial complete)
8 armboot-port from Stephan Linz for the ModNET50 Board.
13 - board with Netsilicon NET+50 ARM7TDMI CPU without MMU
15 - 2 MB Flash (MBL29LV160BE)
16 - 10/100 Ethernet PHY (LXT971A)
19 Current Configuration (include/configs/modnet50.h):
21 Memory Map: 0x00000000 - 0x00FFFFFF 16M SDRAM
22 0x10000000 - 0x101FFFFF 2M Flash
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
28 The environment is located at the end of the 4th Flash
29 sector (0x1001C000-0x1001FFFF).
33 U-boot should be build by using the ELDK Toolchain (arm-linux-*).
41 Everything seems to work fine. Booting images was tested by
42 booting uCLinux (with and without a separate ramdisk image) from
