PetaLinux -- Unable to read file uImage

I have AVNET Mini-ITX 7z100 board and I been trying to use PetaLinux to build a linux image.

I am, however, unable to boot the uImage... not from the uImage which I created myself from the BSP files for the same board nor from the pre-built BIN and uImage files provided by AVNET.

Here is an error which I am receiving when trying to boot from SDCARD with BOOT.BIN and image.ub:

Here are commands which I used ot package my BIN and uImage files (I used both and both failed to boot):

petalinux-package --boot --force --format BIN --fsbl images/linux/zynq_fsbl.elf --fpga images/linux/zynq_design_1_wrapper.bit --u-boot --kernel -o image.ub
petalinux-package --boot --force --format BIN --fsbl images/linux/zynq_fsbl.elf --fpga images/linux/zynq_design_1_wrapper.bit --u-boot

I also have another issue of booting the system (both mine and prebuilt) through JTAG. However, I am not sure if both issues are related (booting via JTAG and via SDcard). Here is what I am getting when trying to boot via JTAG:

Pulsar vs PetaLinux

From the description of the "softdog.nowayout" in the u-boot parameters, that is indicative of a Pulsar Linux boot, not PetaLinux.  Now how can that possibly happen if you have nothing on your uSD card but a PetaLinux boot.bin and image.ub file?  I'm guessing that someone, not necessarily you, saved environment variables for a Pulsar boot in the QSPI.  If that is the case, then those will override the u-boot parameters in your code, and u-boot will dutifully execute the commands in the saved environment.  Which is a completely different setup than you use for a PetaLinux kernel boot.
If at the very beginning of your execution, you don't see text that indicates a "CRC error, using default environment", then u-boot is definitely using the saved environment.  You can see what is saved by stopping u-boot at the command prompt entering "printenv" at the prompt.
From the u-boot used with a PetaLinux kernel build, you can force it to use your default environment from the u-boot prompt:
env default -a
Then you can clear the environment with:  run eraseenv
Try that and see if that works to get your boot going.

I'm getting the same issue with Petalinux 2016.3

I don't have the 'softdog.nowayout=0' in the same way OP does, but I'm also getting complaints of no image.ub:

Hello engsci,

Hello engsci,

Are you also using the Mini ITX? Or are you using a diffrent develpoment board/SOM?
