1 LYNX KDI SUPPORT 2 3 Last Update: July 20, 2003 4======================================================================= 5 6This file describes support for LynuxWorks KDI within U-Boot. Support 7is enabled by defining CONFIG_LYNXKDI. 8 9 10LYNXOS AND BLUECAT SUPPORTED 11============================ 12Both LynxOS and BlueCat linux KDIs are supported. The implementation 13automatically detects which is being booted. When you use mkimage 14you should specify "lynxos" for both (see target-specific notes). 15 16 17SUPPORTED ARCHITECTURE/TARGETS 18============================== 19The following targets have been tested: 20 21-PowerPC MPC8260ADS 22 23 24FILES TO LOOK AT 25================ 26include/lynxkdi.h -defines a simple struct passed to a kdi. 27common/lynxkdi.c -implements the call to the kdi. 28common/cmd_bootm.c -top-level command implementation ("bootm"). 29 30 31==================================================================== 32TARGET SPECIFIC NOTES 33==================================================================== 34 35MPC8260ADS 36=========== 37The default LynxOS and BlueCat implementations require some 38modifications to the config file. 39 40Edit include/configs/MPC8260ADS.h to use the following: 41 42#define CFG_IMMR 0xFA200000 43#define CFG_BCSR 0xFA100000 44#define CFG_BR1_PRELIM 0xFA101801 45 46When creating a LynxOS or BlueCat u-boot image using mkimage, 47you must specify the following: 48 49Both: -A ppc -O lynxos -T kernel -C none 50LynxOS: -a 0x00004000 -e 0x00004020 51BlueCat: -a 0x00500000 -e 0x00507000 52 53To pass the MAC address to BlueCat you should define the 54"fcc2_ether_addr" parameter in the "bootargs" environment 55variable. E.g.: 56 57==> setenv bootargs fcc2_ether_addr=00:11:22:33:44:55:66 58
