  17 # build process for litex sim
  18
  19 very simple:
  20
  21     make run_sim
  22
  23 # build process for ls180
  24
  25 for the variant without 4k srams:
  26
  27     cd soc
  28     make ls180_verilog
  29     cd src/soc/litex/florent
  30     make ls180
  31     cp ls180.il /tmp
  32
  33 at this point you can copy ls180.il over to the coriolis2 chroot,
  34 into soclayout experiments9:
  35
  36     soclayout/experiments9/non_generated/full_core_ls180.il
  37
  38 and you can then begin the build process inside the coriolis2 chroot:
  39
  40     cd soclayout/experiments9
  41     nohup ./build_full.sh &
  42
  43 **note that you will need yosys checkout 049e3abf9 for the coriolis2 build**
  44 this is encoded into the dev-env-setup script which automates the chroot
  45 creation <https://git.libre-soc.org/?p=dev-env-setup.git;a=blob;f=coriolis2-chroot;hb=HEAD>
  46
  47 # build process for ls180 with 4k srams
  48
  49 for the variant with 4k srams:
  50
  51     cd soc
  52     make ls180_4k_verilog
  53     cd src/soc/litex/florent
  54     make ls1804k
  55     cp ls180.il /tmp
  56
  57 at this point you can copy ls180.il over to the coriolis2 chroot,
  58 into soclayout experiments9 in a **different** location from the
  59 above:
  60
  61     soclayout/experiments9/non_generated/full_core_4_4ksram_ls180.il
  62
  63 and you can then begin the build process inside the coriolis2 chroot:
  64
  65     cd soclayout/experiments9
  66     nohup ./build_full_4ksram.sh &
  67
  68 **note that you will need yosys checkout 049e3abf9 for the coriolis2 build**
  69 this is encoded into the dev-env-setup script which automates the chroot
  70 creation <https://git.libre-soc.org/?p=dev-env-setup.git;a=blob;f=coriolis2-chroot;hb=HEAD>
