   5     litex commit 35929c0f8a8f1cc098a6b6ebb569caca8df8c08d
   6     litedram commit 198bcbab676e2b4065e5b6a7dc8a7733bae8315a

  14 # build process for litex sim
  15
  16 very simple:
  17
  18     make run_sim
  19
  20 # build process for ls180
  21
  22 for the variant without 4k srams:
  23
  24     cd soc
  25     make ls180_verilog
  26     cd src/soc/litex/florent
  27     make ls180
  28     cp ls180.il /tmp
  29
  30 at this point you can copy ls180.il over to the coriolis2 chroot,
  31 into soclayout experiments9:
  32
  33     soclayout/experiments9/non_generated/full_core_ls180.il
  34
  35 and you can then begin the build process inside the coriolis2 chroot:
  36
  37     cd soclayout/experiments9
  38     nohup ./build_full.sh &
  39
  40 **note that you will need yosys checkout 049e3abf9 for the coriolis2 build**
  41 this is encoded into the dev-env-setup script which automates the chroot
  42 creation <https://git.libre-soc.org/?p=dev-env-setup.git;a=blob;f=coriolis2-chroot;hb=HEAD>
  43
  44 # build process for ls180 with 4k srams
  45
  46 for the variant with 4k srams:
  47
  48     cd soc
  49     make ls180_4k_verilog
  50     cd src/soc/litex/florent
  51     make ls1804k
  52     cp ls180.il /tmp
  53
  54 at this point you can copy ls180.il over to the coriolis2 chroot,
  55 into soclayout experiments9 in a **different** location from the
  56 above:
  57
  58     soclayout/experiments9/non_generated/full_core_4_4ksram_ls180.il
  59
  60 and you can then begin the build process inside the coriolis2 chroot:
  61
  62     cd soclayout/experiments9
  63     nohup ./build_full_4ksram.sh &
  64
  65 **note that you will need yosys checkout 049e3abf9 for the coriolis2 build**
  66 this is encoded into the dev-env-setup script which automates the chroot
  67 creation <https://git.libre-soc.org/?p=dev-env-setup.git;a=blob;f=coriolis2-chroot;hb=HEAD>
