Hi guys,
I'm usin an iMX53-QSB and I'm trying to explore the ARM TrustZone on this board.
I want to boot my linux 2.6.35 in the normal world. I heard that I need to do some modifications on u-boot. So I have some questions :
-Which uboot do I have to use. The recent one or the 2009.08 ? - Which modification do I have to do ?
- I have to modify also my linux kernel ?
Thank you.
Yes, for i.MX53QSB, the u-boot is 2009.08. Basically, you don't need to modify the u-boot and kernel. After you compile the i.MX53QSB BSP, the board can be boot up by the built images.
If you are first time to use the i.MX53QSB board, it is better to start from the Linux BSP user guide. Following the steps in the user guide to create the images and download the images to the board.
Here is the web page of i.MX53QSB.

You can download the Linux User Guide under "Documentation" and download the BSP source code under "Downloads".
