Please see my post titled "Linux w/ML403 PLB TEMAC". It is basically the tutorial of how I got Linux working on an ML403 board.

Internal Hi It is some thing more than 2 weeks that I'm trying to compile the kernel for ML403. Posted to questions here, but unfortunately, didn't get any answer from the experts here. I have tested every thing I knew ( with my limited knowledge ) and now, I really need your help. I'm using the following set of tools: EDK 8.2.02, ( Latest ) ELDK 4.1 ( Latest ) -I want to compile the 2.6.20 kernel, downloaded from kernel.org -As the first step, in EDK, I choose linux 2.6 in software platform generation settings, -I generate the BSP. -In the generated BSP , I convert all of the 40x strings to 403, also I change the name of xparameters_ml40x to xparameters_ml403 -I copy the 2.6.20 kernel /eldk/ppc_4xx/usr/src/linux , and set all of the needed env variables for cross compile, and set the needed changes in the linux Makefile. ( ARCH and CROSS_COMPILE ) -I copy the entire BSP into the root of the linux kernel. -I edit the linux/arch/ppc/Kconfig file, and add these lines into it: config XILINX_OCP bool "Xilinx OCP" default y config XILINX_TEMAC bool "Xilinx TEMAC" default y config XILINX_SYSACE bool "Xilinx System ACE" default y config XILINX_EDK bool "Xilinx EDK Support" default y -In the linux folder I execute the cow.tcl script provided with the BSP from EDK ( I execute tclsh cow.tcl ) -I make a symbolic link , for config.h file, ( I go to linux/include/linux and then ln -s autoconf.h config.h ) -I begin the menuconfig and set all of the needed parameters -Now, I begin the make process by simply typing : make - I encounter the following error: arch/ppc/platforms/4xx/virtex.c:20: error: array type has incomplete element type arch/ppc/platforms/4xx/virtex.c:60: error: field name not in record or union initializer arch/ppc/platforms/4xx/virtex.c:60: error: (near initialization for 'core_ocp') make[1]: *** [arch/ppc/platforms/4xx/virtex.o] Error 1 make: *** [arch/ppc/platforms/4xx] Error 2 - I can prevent this error by commenting these lines of /arch/ppc/platforms/4xx/virtex.c file: /* Have OCP take care of the serial ports. */ struct ocp_def core_ocp[] = { #ifdef XPAR_UARTNS550_0_BASEADDR { .vendor = OCP_VENDOR_XILINX, .function = OCP_FUNC_16550, .index = 0, .paddr = XPAR_UARTNS550_0_BASEADDR, .irq = XPAR_INTC_0_UARTNS550_0_VEC_ID, .pm = OCP_CPM_NA }, #ifdef XPAR_UARTNS550_1_BASEADDR { .vendor = OCP_VENDOR_XILINX, .function = OCP_FUNC_16550, .index = 1, .paddr = XPAR_UARTNS550_1_BASEADDR, .irq = XPAR_INTC_0_UARTNS550_1_VEC_ID, .pm = OCP_CPM_NA }, #ifdef XPAR_UARTNS550_2_BASEADDR { .vendor = OCP_VENDOR_XILINX, .function = OCP_FUNC_16550, .index = 2, .paddr = XPAR_UARTNS550_2_BASEADDR, .irq = XPAR_INTC_0_UARTNS550_2_VEC_ID, .pm = OCP_CPM_NA }, #ifdef XPAR_UARTNS550_3_BASEADDR { .vendor = OCP_VENDOR_XILINX, .function = OCP_FUNC_16550, .index = 3, .paddr = XPAR_UARTNS550_3_BASEADDR, .irq = XPAR_INTC_0_UARTNS550_3_VEC_ID, .pm = OCP_CPM_NA }, #ifdef XPAR_UARTNS550_4_BASEADDR #error Edit this file to add more devices. #endif /* 4 */ #endif /* 3 */ #endif /* 2 */ #endif /* 1 */ #endif /* 0 */ { .vendor = OCP_VENDOR_INVALID } }; - Instead of the ebove lines, I just put one simple line: ( I use uart lite and not the 16550 so there should be no problem commenting these lines? ) struct ocp_def * core_ocp; - now, I begin the make process again, The make process goes ahead but after a long time it generates another error: GEN .version CHK include/linux/compile.h UPD include/linux/compile.h CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 arch/ppc/syslib/built-in.o: In function `ppc_sys_device_remove': : undefined reference to `ppc_sys_platform_devices' arch/ppc/syslib/built-in.o: In function `ppc_sys_device_remove': : undefined reference to `ppc_sys_platform_devices' arch/ppc/syslib/built-in.o: In function `ppc_sys_device_initfunc': : undefined reference to `ppc_sys_platform_devices' arch/ppc/syslib/built-in.o: In function `ppc_sys_device_initfunc': : undefined reference to `ppc_sys_platform_devices' arch/ppc/syslib/built-in.o: In function `ppc_sys_device_setfunc': : undefined reference to `ppc_sys_platform_devices' arch/ppc/syslib/built-in.o:: more undefined references to `ppc_sys_platform_devices' follow make: *** [.tmp_vmlinux1] Error 1 - If I do not add the BSP files from EDK to my kernel and compile the kernel for ML403, every thing will be completely OK. ( But I want TEMAC ) - when I look in the original virtex.c file, I see that it has defined ppc_sys_platform_devices but when I look at the virtex.c generated by Xilinx, I see that it has a completely different structure, it has no definition of this variable. It is completely different from the original virtex.c - I have tested the same things above, with different versions of 2.6 kernel, such as, 2.6.17.1 and 26-xilinx-devel ( which I download from montavista using git near two weeks ago ) , I also changed the version of eldk to 4.0 and to 3.5 ( with 3.5 I could not compile the kernel at all ) Any idea, Any suggestion and any thing which can help even a litte, is welcome, I really do not know what to do more.
