1 LYNX KDI SUPPORT 2 3 Last Update: July 20, 2003 4 ======================================================================= 5 6 This file describes support for LynuxWorks KDI within U-Boot. Support 7 is enabled by defining CONFIG_LYNXKDI. 8 9 10 LYNXOS AND BLUECAT SUPPORTED 11 ============================ 12 Both LynxOS and BlueCat linux KDIs are supported. The implementation 13 automatically detects which is being booted. When you use mkimage 14 you should specify "lynxos" for both (see target-specific notes). 15 16 17 SUPPORTED ARCHITECTURE/TARGETS 18 ============================== 19 The following targets have been tested: 20 21 -PowerPC MPC8260ADS 22 23 24 FILES TO LOOK AT 25 ================ 26 include/lynxkdi.h -defines a simple struct passed to a kdi. 27 common/lynxkdi.c -implements the call to the kdi. 28 common/cmd_bootm.c -top-level command implementation ("bootm"). 29 30 31 ==================================================================== 32 TARGET SPECIFIC NOTES 33 ==================================================================== 34 35 MPC8260ADS 36 =========== 37 The default LynxOS and BlueCat implementations require some 38 modifications to the config file. 39 40 Edit include/configs/MPC8260ADS.h to use the following: 41 42 #define CONFIG_SYS_IMMR 0xFA200000 43 #define CONFIG_SYS_BCSR 0xFA100000 44 #define CONFIG_SYS_BR1_PRELIM 0xFA101801 45 46 When creating a LynxOS or BlueCat u-boot image using mkimage, 47 you must specify the following: 48 49 Both: -A ppc -O lynxos -T kernel -C none 50 LynxOS: -a 0x00004000 -e 0x00004020 51 BlueCat: -a 0x00500000 -e 0x00507000 52 53 To pass the MAC address to BlueCat you should define the 54 "fcc2_ether_addr" parameter in the "bootargs" environment 55 variable. E.g.: 56 57 ==> setenv bootargs fcc2_ether_addr=00:11:22:33:44:55:66 58
