Crate hifive1

Board file for SiFive HiFive1b RISC-V development platform.

• https://www.sifive.com/boards/hifive1-rev-b

This board file is only compatible with revision B of the HiFive1.

Modules

• io

Structs

• HiFive1 🔒
  A structure representing this platform that holds references to all capsules for this platform. We’ve included an alarm and console.

Constants

• FAULT_RESPONSE 🔒
• NUM_PROCS

Statics

• CHIP 🔒
• PROCESSES 🔒
• PROCESS_PRINTER 🔒
• STACK_MEMORY
  Dummy buffer that causes the linker to reserve enough space for the stack.

Functions

• load_processes_not_inlined 🔒
  For the HiFive1, if load_process is inlined, it leads to really large stack utilization in main. By wrapping it in a non-inlined function, this reduces the stack utilization once processes are running.
• main^⚠
  Main function called after RAM initialized.
• start 🔒 ^⚠
  This is in a separate, inline(never) function so that its stack frame is removed when this function returns. Otherwise, the stack space used for these static_inits is wasted.
