    <p>I'll start by saying that AArch64 RTEMS on QEMU (for which there
      is a ZynqMP hardware model) works great and is what the current
      BSP targets.<br>
    </p>
    <p>The current status of AArch64 RTEMS on real hardware is not as
      simple as I'd like, but it's possible and I've run the
      uniprocessor testsuite tests on an an Avnet dev board (ZU3EG). The
      complications are caused by lack of support for the MMU on AArch64
      leading to all memory requiring strict alignment for accesses. Due
      to this, the toolchain needs to be recompiled with additional
      flags: <br>
    </p>
    <p> --targetcflags="-DPREFER_SIZE_OVER_SPEED -mstrict-align"
      --targetcxxflags="-mstrict-align"</p>
    <p>To deal with an EL2 start, optstarthyp.yml needs to be added to
      the BSP definition and -mstrict-align needs to be added to
      abi.yml.</p>
    <p>Unfortunately, these changes are unfit for inclusion in RTEMS and
      my next step is to work on the MMU driver to avoid these alignment
      problems.</p>

            <p>That exception dump doesn't say a lot other than the ELR
              pointing at the very first instruction in your image, so I
              suspect that u-boot is trying to start your image as
              AArch64 code instead of AArch32/ARMv7 code. The ESR just
              specifies that it was a 32-bit instruction that blew up
              (both AArch32 and AArch64 use 32-bit instructions) instead
              of a 16-bit instruction.</p>
            <p>The u-boot images that come with the PetaLinux
              distributions default to starting code as AArch64 at EL2,
              so you either need to figure out how to make u-boot
              default to AArch32/ARMv7 at EL1 or build a new u-boot that
              can do what you need and then package it into BOOT.bin
              using bootgen (the code is available on github). From what
              I remember, the ARMv7 BSP for ZynqMP mentions booting over
