Hello I am trying to run linux in normal world on genode trustzone. I have changed the run-script of genode to copy the uImage generated from skalk/linux's imx-53 branch instead of downloading (default). I am making uImage with following command:
make uImage LOADADDR=0x70010000
You are trying to relocate the Linux kernel within the memory portion that is used by the secure world (Genode). The secure RAM is from 0x70000000 to 0x7fffffff. Please follow these instructions to build the guest kernel on your own, like referenced within the tz_vmm run-script:

while executing, genode stops after starting virtual machine with following error trace:

Can someone help me with what might be possibly going wrong?
