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