with mpw-5 tag of caravel_user_project, make openlane fails with fetching https://packages.endpoint.com/rhel/7/os/x86_64/endpoint-repo-1.7-1.x86_64.rpm it should be packages.endpointdev.com ? Anyone else hitting this?

I have some experiences like this in unrelated projects where a cached layer is being used. You might want to force rebuilding from scratch

John Simons

02/02/2022, 3:51 PM

Copy code

docker build --no-cache

Matt Venn

02/02/2022, 3:53 PM

Thanks John. as the docker build is buried in makefiles, is there a way I can tell docker to not build from cache as a system config?

Matt Venn

02/02/2022, 3:53 PM

or do I have to find where docker is being called and edit a makefile?

John Simons

02/02/2022, 3:54 PM

I am not sure, but I think you can deduce it from the error (IMAGE_NAME=blabla)

John Simons

02/02/2022, 3:54 PM

I’ll be setting up myself in a bit if you have not solved it then I will check it for you

Matt Venn

02/02/2022, 3:56 PM

thanks, I just tried but running the docker command from the makefile fails with errors I don't understand

Matt Venn

02/02/2022, 3:56 PM

let me know if you manage it

John Simons

02/02/2022, 3:56 PM

you might post it here and I might be able to help

John Simons

02/02/2022, 3:56 PM

(the error I mean)

Matt Venn

02/02/2022, 3:57 PM

just closed the window and I've got to get on with other stuff now -sorry

John Simons

02/02/2022, 3:57 PM

no problem, I’ll let you know the full command later - or anything else I find

Harald Pretl

I just now started to try the latest OpenLane with mpw-5, stay tuned…

Matt Venn

02/02/2022, 4:10 PM

That's what I just did

Harald Pretl

02/02/2022, 4:12 PM

works?

Matt Venn

02/02/2022, 4:16 PM

Harald Pretl

02/02/2022, 4:19 PM

I have started

make user_proj_example

, so far so good 🙂

John Simons

02/02/2022, 4:22 PM

can confirm the issue

John Simons

02/02/2022, 4:22 PM

make openlane errors out. brb with a fix

Matt Venn

02/02/2022, 4:22 PM

what tag @User?

Harald Pretl

02/02/2022, 4:25 PM

@User currently testing this, so far so good:

Copy code

export CARAVEL_USER_PROJECT_COMMIT=mpw-5
export CARAVEL_COMMIT=mpw-5
export OPEN_PDKS_COMMIT=476f7428f7f686de51a5164c702629a9b9f2da46

Passes build of

user_proj_example

, fails on

user_project_wrapper

with

couldn't read file "/home/harald/caravel_env_new/caravel_user_project/caravel/openlane/user_project_wrapper_empty/fixed_wrapper_cfgs.tcl": no such file or directory

John Simons

02/02/2022, 4:29 PM

I think that bug is known and has a solution

John Simons

02/02/2022, 4:29 PM

but it’s in one of the other channels

John Simons

02/02/2022, 4:30 PM

or above

John Simons

02/02/2022, 4:31 PM

@User I think that this commit is a no-go. The Dockerfile indeed refers the wrong URL and is hardcoded. It also cannot be modified in the file as it won’t accept a non-empty folder as it’s OPENLANE_ROOT

👍 1

John Simons

02/02/2022, 4:32 PM

but it might be possible to use the latest Openlane (though that is not signed off on) for now with Harald’s config

Matt Venn

02/02/2022, 4:41 PM

we'll wait for efabless to give us some working tags

Matt Venn

02/02/2022, 4:42 PM

@User @User

02/02/2022, 4:59 PM

Keep in mind, there is long list of known bugs in upstream openlane, that may or may not affect you.

Arman Avetisyan

02/02/2022, 5:00 PM

Most of these bugs arent in v0.23

donn

02/02/2022, 5:00 PM

v0.23 is horribly out of date, please don't mix and match caravel components. we'll patch the endpoint issue

Harald Pretl

02/02/2022, 5:22 PM

So I hacked my way through, so that

make user_proj_example

and

make user_project_wrapper

run. First, I use this to build everything:

Copy code

export CARAVEL_LITE=0
export CARAVEL_USER_PROJECT_COMMIT=mpw-5
export CARAVEL_COMMIT=mpw-5
export OPEN_PDKS_COMMIT=476f7428f7f686de51a5164c702629a9b9f2da46
export OPENLANE_TAG=2022.02.01_02.19.58

Then, I change this

Copy code

diff --git a/openlane/user_project_wrapper/config.json b/openlane/user_project_wrapper/config.json

Harald, please do not change the OpenLane version. Traceability is already something of a nightmare. I've submitted a very quick one-line fix in the other thread.

@User OK, I’ll switch back and use

make pull-openlane

So what is the correct OpenLane tag now to use?

donn

02/02/2022, 5:25 PM

Do not change the OPENLANE_TAG specified by caravel.
