		doublerabbit 49 days ago \| parent \| context \| favorite \| on: Easy RISC-V Within the basic "123" ASM demo, I get that x10 - Becomes 0x00000123 as we are taking the integer of x0 and applying 123 to end of it but why is the sp (x2) register at 0x40100000? What is that sp? Is it important? Why isn't that at 0x000000? Why isn't that explained? That's when I get lost.

'sp' is the 'stack pointer' register. There's an explanation of the stack later in the guide: https://dramforever.github.io/easyriscv/#the-stack
