If you don’t know any assembly programming or perhaps don’t know much coding at all then RISC-V may be one of the better assembly languages to start with. Sure, there are way more x86 assembly tutorials out there. More people who could help you. But x86 is a beast with over 1500 different instructions.
RISC-V in contrast was made specifically to be easy to teach while pragmatic enough to actually allow the implementation of high performance microprocessors.
