VMM on i.mx53 quick start board

That’s just stupid: you cannot load the image to the same address (ext2load mmc 0 0x70010000 /home/lucid/uImage) where the unzipped kernel image is expected to reside (Load Address: 70010000). You must load /home/lucid/uImage to a location where it will not overlap with the unzipped kernel image, for instance 71000000, and then use the same address with bootm.

Subject: VMM on i.mx53 quick start board


I want to the use VMM on i.mx53 quick start board. I followed the following building steps and managed to produce the image file in the build dirctory (var/run/tz_vmm/uImage). I am using the master branch of Genode's mainline repository.

    tool/create_builddir hw_imx53 BUILD_DIR=hw_imx53
    cd hw_imx53
    echo "SPECS += trustzone" >> etc/specs.conf
    echo "RUN_OPT = --target uboot" >> etc/build.conf
    make run/tz_vmm

And then, i loaded the uImage to address 0x70010000 using u-boot command as follows.

    MX53-LOCO U-Boot > ext2load mmc 0 0x70010000 /home/lucid/uImage
    Loading file "/home/lucid/uImage" from mmc device 0:1 (xxa1)
    7858766 bytes read

Finally, i tried to boot the demo and i got the following error. Anyone knows about this?

    MX53-LOCO U-Boot > bootm 0x70010000
    ## Booting kernel from Legacy Image at 70010000 ...
