Dear Ameet, Sorry to bother you again but I am totally confused on the systemACE driver. First let me show you the problem.
1. I downloaded the linux kernel of 2.6.17.1, also the patch for SystemACE driver. Applied the patch to the kernel. Replaced the xparameters_ml403.h with the generated file xparameters_ml300.h from Xilinx EDK. Make menuconfig, make dep and make zImage. Then the error shows like this: drivers/block/xilinx_sysace/xsysace.c:120:6: warning: "XPAR_XSYSACE_MEM_WIDTH" is not defined drivers/block/xilinx_sysace/xsysace.c: In function `XSysAce_LookupConfig': drivers/block/xilinx_sysace/xsysace.c:366: error: `XPAR_XSYSACE_NUM_INSTANCES' undeclared (first use in this function) drivers/block/xilinx_sysace/xsysace.c:366: error: (Each undeclared identifier is reported only once drivers/block/xilinx_sysace/xsysace.c:366: error: for each function it appears in.) make[3]: *** [drivers/block/xilinx_sysace/xsysace.o] Error 1 make[2]: *** [drivers/block/xilinx_sysace] Error 2 make[1]: *** [drivers/block] Error 2 make: *** [drivers] Error 2 I think this is because of the no inclusion of the xparameters header file. So I change #include "xparameters.h" into #include " /home/mingliu/linux-2.6.17.1/arch/ppc/platforms/4xx/xparameters/xparameters.h" in the files of xsysace.c and xsysace_g.c, using the full address to specify the header file. In fact, this is not a serious problem and it often happens. But, after the modification, another problem happened: GEN .version CHK include/linux/compile.h UPD include/linux/compile.h CC init/version.o LD init/built-in.o LD .tmp_vmlinux1 drivers/built-in.o(.text+0x2234a): In function `XSysAce_GetCfgAddr': : undefined reference to `XAssertStatus' drivers/built-in.o(.text+0x2235e): In function `XSysAce_GetCfgAddr': : undefined reference to `XAssertStatus' drivers/built-in.o(.text+0x22364): In function `XSysAce_GetCfgAddr': : undefined reference to `XAssert' drivers/built-in.o(.text+0x22372): In function `XSysAce_GetCfgAddr': : undefined reference to `XAssertStatus' drivers/built-in.o(.text+0x2237a): In function `XSysAce_GetCfgAddr': : undefined reference to `XAssertStatus' drivers/built-in.o(.text+0x22394): In function `XSysAce_GetCfgAddr': : undefined reference to `XAssert' drivers/built-in.o(.text+0x223a2): In function `XSysAce_GetCfgAddr': : undefined reference to `XAssertStatus' drivers/built-in.o(.text+0x223aa): In function `XSysAce_GetCfgAddr': : undefined reference to `XAssertStatus' drivers/built-in.o(.text+0x22cd6): In function `XSysAce_Initialize': : undefined reference to `XAssertStatus' drivers/built-in.o(.text+0x22cdc): In function `XSysAce_Initialize': : undefined reference to `XAssert' drivers/built-in.o(.text+0x22cea): In function `XSysAce_Initialize': : undefined reference to `XAssertStatus' ......( a long information to say that undefined reference to the XAssert things.) Also, I tried this in the kernel 2.6.16-rc5. (In fact I prefer this version because the temac driver is for this version. ) The same problem happened. I checked the source code. The problem happened in the file driver/block/xilinx_sysace/adapter.c, etc. Also, the XAssert things are defined in the file arch/ppc/platforms/4xx/xilinx_ocp/xbasic_types.c. (In 2.6.16 kernel, it is also defined in driver/xilinx_edk/xbasic_types.c. There are two copies of this file. ) I think the problem is, the systemACE files cannot link together with the xbasic_types.c file. I heard that you have tested this driver. Have you got this problem? Why there are so many strange problems for me while you have tested without problem? Without the CF card, I cannot try the Temac driver and my work is totally blocked. So I have to ask for your suggestion. Really anxious for your useful guidance. Thanks a lot!!!!!! Regards Ming _________________________________________________________________ ??????????????
