    linux karnal uImage problam cant synchronize with .dtb file

    varunshah

      hello every one
         I am using zynq ZC703 and i make a u-boot.elf ,Uimage and system.dts file.
      1> i made a u-boot.elf file by following command
              make zynq_zc70x_config
              make all
              cp u-boot u-boot.elf

      2> i made a vivardo project and made export hardwear in SDK
           in SDK Xilinx Toos-> Repositories i add device-tree-xlnx- (downloaded from git hub)
           after that File->New->Board Support package i make devicetree system.dts file
           i made system.dtb file by
              dtc -I dts -O dtb -o system.dtb system.dts

      3>i downloaded linux-xlnx from git hub and make uImage by
           make ARCH=arm UIMAGE_LOADADDR=0x8000 uImage

      bui i thing system.dts and uImage are not synchronize so i change uImage ,turned off the fixed device tree address in the kernel configuration by make ARCH=arm menuconfig

      System Type->Xilinx Specific Features -> Device Tree At Fixed Address



      But here is terminal output

        • Device Tree is likely the culprit
          hockeyman1972

          I think you are correct that the device tree does not match your hardware design.  There is a device tree generator tool available from Xilinx;  you might try running that and compare the results to the version you are using from the github.   Or you can try using a PetaLinux BSP for the board you are using, and compare the device tree source from there with yours.   Booting the system with PetaLinux will at least give you some confidence there are no issues with the hardware design.
