compiled kernel image: cannot execute binary file

I'm working with T10 series, specifically the T1023RDB. 

Here's my problem:

  1. I compile a linux image, a root file system, and device tree for the target board
    • bitbake fsl-image-core
  2. I boot from these binaries following the directions in the SDK manual. 
    • tftp 1000000 uImage
    • tftp 4000000 fsl-image-core-t1023rdb.ext2.gz.u-boot
    • tftp 9000000 uImage-t1023rdb.dtb
    • bootm 1000000 4000000 9000000
  3. I build the toolchain and source the environment file (same board support package as the kernel image)
    • bitbake fsl-toolchain
    • bash tmp/deploy/sdk/(install-file-name).sh
    • source /opt/fsl-qoriq/2.0/(environment-setup-name).sh
  4. I compile a simple C program with this environment  
    • $CC hello.c -o hello.x
  5. I try to run it on the board and I get this message : "cannot execute binary file"
    • (configure the ethernet ports, acquire hello.x)
    • . ./hello.x
    • -sh: .: ./hello.x: cannot execute binary file


Frankly, I'm stumped. The interpreter is /lib/ which seems to be present on the board. Oddly enough, if I just let the board boot without using my images, the executable can run just fine.
