Topic: Moving SD cards from FreeScale EVK
I have developed an application running from SD card (2GB) using the FreeScale imx233 EVK Evaluation board. This app and SD boot works fine on this development board. I have reviewed the Hacker Board and it rather closely matched the Freescale design. Just for a test I'd like to see if the SD boots on a Hacker Board. I have a Chumby 1 here (used in my home) and so I thought I'd just try my SD in it as a quick test before buying the Hacker Board. I just wanted to see the Boot debug.
Here is what I found: The Chumby SD will not boot on the FreeScale EVK dev board.

Serial debug simply displays error code 0x8020a00f on power up. To me this indicates the Chumby SD is encrypted and ONLY can boot in a Chumby that has a the security fuses set for a KEY on the IMX23 to talk to the exact SD Boot that comes with the Chumby.
Could this be true?
Question. Does a real Chumby use the Imx233 internal security fuses to decode their SD at boot? More importantly, does anyone know if the Hacker Board has fuses are intact so I can try MY FreeScale SD Boot (not just the one that comes with the Hacker board)
