Thanks a lot Stefan for your explanation about the driver configuration. I followed your roadmap and tried to configure the drivers with help of the driver subsystem file that you mentioned for virt_qemu_arm_v8a platform and generated the image.elf at / *genode/build/arm_v8a/var/run/sculpt/boot/image.elf.* While executing it to get the gui on QEMU i got the following error message.
Maybe I did something wrong in the *genode/repos/gems/sculpt/drivers/virt_qemu_arm_v8a* and missed any drivers in the /*genode/repos/gems/sculpt/default-virt_qemu_arm_v8a.sculpt*. Also I am not sure how to write this configuration. Kindly guide me to configure the required drivers to boot the image in qemu. Regards, Divya.
