In particular, check the chip select values -installed into the memory controller's various option and base -registers - these are set by the defines CONFIG_SYS_CMA_CSn_{BASE,SIZE} and -CONFIG_SYS_{B,O}Rn_PRELIM. Also be careful of the clock settings installed -into the SCCR - via the define CONFIG_SYS_SCCR. Finally, decide whether you -want the serial console on motherboard serial port A or on one of the -8xx SMC ports, and set CONFIG_8xx_CONS_{SMC1,SMC2,NONE} accordingly -(NONE means use Cogent motherboard serial port A). - -Then edit the file "cogent/config.mk". Firstly, set CONFIG_SYS_TEXT_BASE to be -the base address of the EPROM for the CPU module. This should be the -same as the value selected for CONFIG_SYS_MONITOR_BASE in -"include/config_cogent_*.h" (in fact, I have made this automatic via -the -CONFIG_SYS_TEXT_BASE=... option in CPPFLAGS). - -Finally, set the values of the make variables $(CMA_MB) and $(CMA_IOMS). - -$(CMA_MB) is the name of the directory that contains support for your -motherboard. At this stage, only "cma10x" exists, which supports the -CMA101 and CMA102 motherboards - but only selected devices, namely -serial, lcd and dipsw. - -$(CMA_IOMS) is a list of zero or more directories that contain -support for the i/o modules you have installed. At this stage, only -"cma302" exists, which supports the CMA302 flash i/o module - but -only the flash part, not the ps/2 keyboard and mouse interfaces. - -There should be a make variable for each of the above directories, -which is the directory name with "_O" appended. This make variable is -a list of object files to compile from that directory and include in -the library. - - e.g. cma10x_O = serial.o ... - -That's it. Good Luck. - -Murray.Jensen@cmst.csiro.au -August 31, 2000. |
