TDA4VM: TDA4VM 1.1

Part Number: TDA4VM

Hi Ti,

  In order to save flash space and reduce the kernel image size, I want to use the compressed kernel image (vmlinux.gz/ image.gz),

but, i found that there were no code for compression/decompression in arch/arm64/boot/. I use SDK8.0.

  How to use compressed  image(vmlinux.gz/Image.gz /uImage)to boot kernel ?  Does u-boot need corresponding change or coordination?

BRs.

Thanks.

    Hi,

    The default SDK does not support the compressed image loading. If you have eMMC then we support flashing from rootfs ext4 partition.

    Hi Keerthy J,

      Thanks for your quick response.

     I can flash  the image of Kernel to rootfs ext4 partition.  Now, i want to flash compressed  image of Kernel to OSPI flash.

    Do you have plan to support  compressed image of kernel  in the future?

    Merry Christmas!

    BRs.

    Okay good to know that you are able to flash kernel from ext4 partition of eMMC.
