After following the new set of instructions getting error that "user_preject_wrapper/config.tcl" not present. For GF we are using config.json. Do have to create config.tcl again?

I think @jeffdi'sinstructions were assuming you were updating from the

gfmpw-0b

tag. If you are updating from

gfmpw-0a

more changes are necessary, see the patches attached to https://github.com/efabless/caravel_user_project/releases/tag/gfmpw-0d
