  1. LYNX KDI SUPPORT
  2. Last Update: July 20, 2003
  3. =======================================================================
  4. This file describes support for LynuxWorks KDI within U-Boot. Support
  5. is enabled by defining CONFIG_LYNXKDI.
  6. LYNXOS AND BLUECAT SUPPORTED
  7. ============================
  8. Both LynxOS and BlueCat linux KDIs are supported. The implementation
  9. automatically detects which is being booted. When you use mkimage
  10. you should specify "lynxos" for both (see target-specific notes).
  11. SUPPORTED ARCHITECTURE/TARGETS
  12. ==============================
  13. The following targets have been tested:
  14. -PowerPC MPC8260ADS
  15. FILES TO LOOK AT
  16. ================
  17. include/lynxkdi.h -defines a simple struct passed to a kdi.
  18. common/lynxkdi.c -implements the call to the kdi.
  19. common/cmd_bootm.c -top-level command implementation ("bootm").
  20. ====================================================================
  21. TARGET SPECIFIC NOTES
  22. ====================================================================
  23. MPC8260ADS
  24. ===========
  25. The default LynxOS and BlueCat implementations require some
  26. modifications to the config file.
  27. Edit include/configs/MPC8260ADS.h to use the following:
  28. #define CONFIG_SYS_IMMR 0xFA200000
  29. #define CONFIG_SYS_BCSR 0xFA100000
  30. #define CONFIG_SYS_BR1_PRELIM 0xFA101801
  31. When creating a LynxOS or BlueCat u-boot image using mkimage,
  32. you must specify the following:
  33. Both: -A ppc -O lynxos -T kernel -C none
  34. LynxOS: -a 0x00004000 -e 0x00004020
  35. BlueCat: -a 0x00500000 -e 0x00507000
  36. To pass the MAC address to BlueCat you should define the
  37. "fcc2_ether_addr" parameter in the "bootargs" environment
  38. variable. E.g.:
  39. ==> setenv bootargs fcc2_ether_addr=00:11:22:33:44:55:66
