Hi,
The mechanism used in the tutorial would work for any compiler that produces ELF files that can be debugged by gdb (ARM Clang V6 is compatible). However the specific steps (e.g. the exact compiler arguments or the linking order) could be different.
We currently don’t have an out-of-the-box tutorial for the ARM Clang compiler, so we would advise trying to follow the regular Keil tutorial and making the necessary changes to account for the different compiler. If you encounter any difficulties along the way, feel free to post the details here and we will help you resolve any issues you encounter.
