4.16.1. or1ksim

Compile or1ksim emulator:

$ cd ~/
$ git clone https://github.com/openrisc/or1ksim
$ cd or1ksim
$ ./configure
$ make

Create minimal or1ksim.cfg file:

section cpu
  ver = 0x12
  cfgr = 0x20
  rev = 0x0001
end

section memory
  name = "RAM"
  type = unknown
  baseaddr = 0x00000000
  size = 0x02000000
  delayr = 1
  delayw = 2
end

section uart
  enabled = 1
  baseaddr = 0x90000000
  irq = 2
  16550 = 1
  /* channel = "tcp:10084" */
  channel = "xterm:"
end

section ethernet
  enabled = 1
  baseaddr = 0x92000000
  irq = 4
  rtx_type = "tap"
  tap_dev = "tap0"
end

Run or1ksim:

$ ~/or1ksim/sim -f or1ksim.cfg barebox
