IMX6 SabreLite: same sdcard on different board gives different bootup?

I have found a strange problem on IMX6 SabreLite from Boundary Device.

I created my own linux 3.0.35 platform with a camera driver OV5640 enabled on an micro-sdcard.

On start up, my platform would check the presence of OV5640 camera and show a message.

My colleague who is working on OV8820 on another IMX6 SabreLite board.

When I put my micro-sdcard into my colleague's board, it shows me "OV8820 is not found" instead of OV5640.

I have not even built OV8820 driver into my micro-sdcard.

 

We both did not change the u-Boot in SPI flash, it is U-Boot 2015.07-15072-g45cfc85 (Jan 28 2016 - 17:41:49 -0700), Build: jenkins-uboot_v2015.07-30.

It looks like some contents of my colleague's project is burnt into his board and mix up with my project.

I am pretty sure our board is booting up on micro-sdcard (mmc1) because without my card the system does not boot.

 

This will cause a huge problem because I cannot even know whether any new problem is due my project or the mix-up of two project.

 

Can any body knows how to solve this project mix-up issue and how I can confirm the project is purely mine?
