hello, i am tring a entire caravel walkthrough. So can i try a project from MPW5 without considering someting like

OPENLANE_TAG,SKYWATER_COMMIT...

difference between MP5 and MP7? I do that but it looks like some mistakes happened when i run

make user_proj_exmaple

,it said

permission denied

when cd in dependences/pdks/sky130A,but MPW7's sample project run well ,is that because different

OPENLANE_TAG,SKYWATER_COMMIT...

in two makefile? and mistakes happened in the process of

make pdk

although it finished the

make pdk

command.
