kernel fails to load in p1022 board

[hemwant]

I am having a custom board based on P1022 processor, I wanted to update the kernel to 4.1.8(extracted from QorIQ2.0) from earlier 3.12.37 (extracted from BSP QorIQ1.8) . I have extracted the kernel source of QorIq2.0 and compiled the same kernel using p1022 toolchain. I have successfully generated the kernel image but when i try to load the kernel in my board it fails to load throwing the following exception.

Note: The same earlier kernel 3.13 when again loaded into the above board works properly and boots the linux.

Hello Hemwant Rawat,

Please try whether the attached uImage can work on your target board, which I got from SDK 2.0 e500v2 pre-built image ISO.

Would you please provide your uImage and dtb file? I will verify them on my demo board.

Thanks,

Yiping

Hello yipingwang‌

I have tried to run your attached kernel , please find attached its log.

Also Please  find my kernel and dtb image.

Hello Hemwant Rawat,

I verified your uImage file, encountered same problem as you.

There is problem with uImage which you built.

You could refer to the following procedure to build Linux Kernel image.

Please download SDK image ISO for e500v2, then install Toolchain for e500v2, and execute the following command.

$ source /opt/fsl-qoriq/2.0/environment-setup-ppce500v2-fsl-linux-gnuspe

$ cp arch/powerpc/configs/mpc85xx_defconfig .config

$ make ARCH=powerpc menuconfig

$ unset LDFLAGS

$ make uImage CC="powerpc-fsl-linux-gnuspe-gcc --sysroot=/opt/fsl-qoriq/2.0/sysroots/ppce500v2-fsl-linux-gnuspe"

Thanks,

Yiping

Thank you yipingwang‌, using the above steps I was able to configure the kernel and compile it successfully.
