When running precheck at efabless I am getting:
```[12/24/21 00:20:39 PST] IDENTIFYING PROJECT TYPE FAILED
A single valid GDS was not found.

[12/24/21 00:20:39 PST] EXCEPTION
Script error code: 254```
However I do have gds folder with gds files there:
<https://github.com/roman3017/caravel_mpw4/tree/main/gds>
Anyone knows how project identification works and what am I missing there?
The local precheck works fine.

sounds like a problem with the caravel repository

I continue to use mpw-3 tag for caravel_user_project

<@U01HS0N8KNW> Have you used SRAM in `user_proj` , try removing sram*.gds from the gds directory.

Because if you have hardened your design with SRAM macro in it, the GDS of `user_proj` would have the necessary info about SRAM. So you do not have to put the GDS there separately

Removing SRAM GDS/LEF/LIB does not help, since it failed first without it. I added them there after precheck failed the first time hoping it would fix it. The caravel tag used is whatever efabless has configured in their precheck and I do not have a control over it. Locally it works for me.
