Hi all,
I am trying to enable TrustZone for imx6 processor. As earlier, I have
modified Genode for imx6 and it was successfully running. And I am able to
run Genode in secure world as well as in Normal world on imx6 tablet.
Now i am trying to run Linux (3.10 without dtb) in the Normal world. I
tried the follow the following steps:
1) I simply followed the steps mentioned on the following link
http://boundarydevices.com/cross-compile-i-mx6-kernel-using-ltib-toolchain/
which generate uImage which is successfully running on imx6 with
LOADADDR=30008000.
2) I simply copied this uImage as "linux" in <Genode>/<Build_Dir>/bin/
folder
3) run the modified tz_vmm script and build the uImage.
I run the uImage on the imx6 board.Following is the generated output:
9928768 bytes read in 523 ms (18.1 MiB/s)
## Booting kernel from Legacy Image at 10800000 ...

I am using Genode-14.11 and u-boot 14.07 to run this image. I set the
NONSECURE_RAM_BASE=0x30000000 and kernel_offset=8000. I know i haven't
modified linux according to the normal world but at least kernel should
start in normal world.
What could be the reason or some thing wrong in the steps due to which
Linux is not able to start in Normal world ?
Thanks in advance.
