Could you run "file images/capdl-loader-image-arm-tk1"? If you see "images/capdl-loader-image-arm-tk1: MS-DOS executable", the image is an EFI image, so bootefi command should help.
Also, the link, https://docs.sel4.systems/Hardware/jetsontk1.html, may be helpful.

Looks like I might have spoken too soon. When I use go instead of bootelf, the board actually resets. Here are the log messages:

Doing readelf on the image that is being built doesn't work either
$ readelf -h capdl-loader-image-arm-tk1 readelf: Error: Not an ELF file - it has the wrong magic bytes at the start
My old images from a year ago still boot just fine with bootelf. Any thoughts?

Can you do a readelf of your outputted image to make sure its not compiling as a binary? If it is, you’ll have to use the “go” command in u-boot instead.

CAUTION: This email originated from outside the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe. I'm using the docker image to build the CAmkES ARM VMM project using roughly the instructions here: https://docs.sel4.systems/VM/CAmkESARMVM.html (they are slightly out of date).
../init-build.sh -DAARCH32=TRUE -DCAMKES_VM_APP=vm_minimal -DPLATFORM=tk1
Then I copy the resulting image from the images directory to an SD card and put that in my TK1.
When U-Boot starts I use the following commands to try to boot
fatload mmc 1 0x10000000 capdl-loader-image-arm-tk1
To which I get an error: No elf image at address 0x10000000
I tried with an older version of U-Boot (that worked following this same procedure about a year ago). It is U-Boot SPL 2014.10- rc2-g3127911 (Jun 07 2016 - 21:00:01)
I also tried updating U-Boot to U-Boot SPL 2020.01-00442- gc00bd81ae0 (Jan 10 2020 - 11:10:18 -0500). Same error.
Any thoughts or suggestions on how I get this to boot?
