you need "git checkout LS180_RC8_FINAL"
followed by "git submodule update --init --recursive"
(this is in the build script)

if you do this:

(coriolisnew2)lkcl at fizzy:~/soclayout/experiments9$ git submodule
 470660aad064b956d2b61d95f25f405fc0bd0358 ../c4m-pdk-freepdk45
(released_v0.0.1-5-g470660a)
 d96f737c0a53dde983060522816bbef016b449ce ../pinmux (d96f737)

you should have pinmux at d96f737....

"make pinmux" creates the json file (again, this is in the build script)
