Hi Martin, thank you so much! it works for me. Now I just need to use the sd_card driver with Genode trustzone feature (hw_imx53_qsb_tz). I tried to incorporate sd_card driver with tz_vmm run script and make run/tz_vmm. I get the following log messages and it gets stuck. it doesn't even run tz_vmm

Hi Christian, Thank you so much! Now it works. There was a problem with the file system (ram_fs) configuration in the run script. But it only works when i perform the file access inside the *main()* function of tz_vmm. it generates the following error when i try to access the file inside *_handle

Noux application

Hi everyone, I am running a simple "tz_vmm" example in Genode on imx53 qsb. I have Noux application which runs on top of Noux runtime inside the secure world. I wanted to access this Noux applications inside tz_vmm application, calling a function of Noux application from tz_vmm code.
