Dear All, When I looked into the linux-2.6.36/arch/arm directory, I did not find the mach-s3c2510/s3c2510a directory for Samsung s3c2510a MCU. When I asked the same in the ARM forum, they told me that this MCU is a NO-MMU based MCU and in the current kernel there was no much support for it. For complete details, please look at the following link. http://comments.gmane.org/gmane.linux.ports.arm.kernel/108351 So, I started developing the architecture files for my MCU i.e. Samsung S3C2510A. However, when I am trying to build the kernel after adding the support for S3C2510A processor, I am getting the following error. CC init/main.o In file included from /home/madhavi/linux-2.6.36/arch/arm/include/asm/cacheflush.h:15:0, from include/linux/highmem.h:9, from include/linux/pagemap.h:10, from include/linux/mempolicy.h:70, from init/main.c:50: /home/madhavi/linux-2.6.36/arch/arm/include/asm/glue.h:119:2: error: #error Unknown data abort handler type make[6]: *** [init/main.o] Error 1 make[5]: *** [init] Error 2 make[5]: Leaving directory `/home/madhavi/linux-2.6.36' make[4]: *** [/home/madhavi/linux-2.6.36/.image] Error 2 When I looked into the sources of the /arch/arm/include/asm/glue.h file, none of the macro defines the CPU_DABORT_HANDLER. From the arch/arm/Makefile the abort handler for no-mmu based CPUs is as follows. obj-$(CONFIG_CPU_ABRT_NOMMU) += abort-nommu.o In my case, the CONFIG_CPU_ABRT_NOMMU is defined in .config file to y. My question is, why again it is trying to check the abort handler from glue.h file? Shall I add a new macro in the glue.h file for defining the CPU_DABORT_HANDLER based on this new MCU (Samsung S3C2510A)? Any ideas / hits would be appreciated. Thanks for your help.
