When programming explicitly in RISC-V assembly language, it is mandatory to load x2 with the stack base address while the C/C++ compilers for RISC-V, are always designed to use x2 as the stack pointer.

The RISC-V system uses a single function pointer to a physical address in the kernel. Whenever something happens, the CPU will switch to machine mode and jump to the function.

There is an additional user-visible program counter pc register which holds the The convention used with RISC-V is that the return address should be stored with the return address register ra which is x1.

2017-08-14 · Before we can board the RISC-V train, we'll have to take a stop at the metaphorical ticket office: our machine-specific GCC command-line arguments. These arguments all begin with -m, and are all specific to the RISC-V architecture port. In general, we've tried to match existing conventions for these arguments, but like pretty much everything else there are enough quirks to warrant a blog post # read_registers Register 0x02 = 0x1a Register 0x03 = 0x0b Register 0x04 = 0x00 Register 0x05 = 0x52 This command reads the SX1276 Registers over the SPI Connections.
