  1. U-BOOT Port for FSForth ModNET50 Board
  2. --------------------------------------

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