Zynq-7000 SoC OS - Make Errors When Building the Linux Kernel


The following occurs while building the Linux kernel for Zynq:

#> make ARCH=arm uImage
  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  CHK     kernel/config_data.h
  CC      drivers/char/xilinx_devcfg.o
drivers/char/xilinx_devcfg.c: In function 'xdevcfg_drv_probe':
drivers/char/xilinx_devcfg.c:1504:2: error: implicit declaration of function 'of_get_next_parent' [-Werror=implicit-function-declaration]
drivers/char/xilinx_devcfg.c:1504:5: warning: assignment makes pointer from integer without a cast [enabled by default]
drivers/char/xilinx_devcfg.c:1505:5: warning: assignment makes pointer from integer without a cast [enabled by default]


How do I resolve this?


This occurs because the GNU tool chain is not set up correctly.

For building up the Linux kernel, ensure that the GNU tools are set up properly based on the instructions from the Xilinx wiki: http://wiki.xilinx.com/zynq-tools

Once the tools are setup properly, try the build command again.

The complete information for this flow is available on the Xilinx wiki: http://wiki.xilinx.com/zynq-linux#toc9
