- U-BOOT Port for FSForth ModNET50 Board
- --------------------------------------
- author: Thomas Elste <info@elste.org>
- IMMS gGmbH <www.imms.de>
- 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.
