Running Yocto Project image

Boot sequence fails with "Failed to mount /uboot" and "codepage cp437 not found"

This sometimes happens when using one of the minimal images from the Yocto Project, such as core-image-minimal or core-image-full-cmdline. These images do not include the kernel-modules package, which contains the kernel module with codepage 437. There are two ways this can be resolved:

  • If you're compiling a custom kernel, it is recommended to set the kernel configuration option:


    Please refer to the Yocto Project Manual for how to use menuconfig to generate and save defconfig files for the kernel.

  • If you're not building a custom kernel, you can add this line to your local.conf in order to include all the kernel modules in the image:

    IMAGE_INSTALL_append = " kernel-modules"

    This is an easier fix, but also requires more space in the image than the previous solution, since all modules will be included, not just the missing one.
