[seL4] Running CAmkES Sample Application on Sabre Lite Board

I was following the CAmkES "Getting Started" tutorial on the seL4 website and followed all the instructions. Here is the link: https://sel4.systems/Info/CAmkES/GettingStarted.pml I managed to get the sample application to run in QEMU (Quick Emulator) like the instructions said. I tried loading the sample application onto the Sabre Lite Board through tftp booting using minicom. However, once I try to boot the .elf file, it displays the memory address and nothing else happens. Is there any configuration file that I need to change to make the sample application run on my Sabre Lite Board? Or is there something else that I am missing? Thanks, Bryan
