Hello world boot imx6sxsabre

Hi all,


New to Linux and IMX products.  I'm trying to get a simple "Hello world" to boot - with obvious difficulties. 


My initramfs simply consists of the Hello world executable (static) renamed init.  I give the menuconfig the absolute path to the init file and then bitbake linux-imx.  I can see the size of zimage change so I know it is being built into the kernel.  I then use MGFTool to burn zimage and the dtb into the qspi2 on the board.  Once program (at u-boot prompt), - I then "sf probe, sf read ${loadaddr} 0xA00000 0x660000, sf read ${fdt_addr} 0x800000 0x10000, bootz ${loadaddr} - ${fdt_addr}".


The board begins the long boot process and then fails with the following:


Warning: unable to open an initial console.

Freeing unused kernel memory: 352K (80c72000 - 80cca000)

Failed to execute /init

Kernel panic - not syncing: No init found.  Try passing init= option to kernel.

See Linux Documentation/init.txt for guidance.


I have searched and experimented for multiple days scouring the internet for the solution - so here I am admitting defeat.  Furthermore, my end game is just using the initramfs as my final rootfs; however, that experiment failed as well. 

Can anyone point a newbie in the right direction.


Thank you
