Does this filmware work with esp32-s3?

[hello-world12]

I am having issues trying to get this filmware to function on my esp32-s3 for some time. Has anyone made this filmware work with esp32-s3? I'm pretty new to this type of stuff, So I may be missing infromation.

It can be built for esp32-s3 (we have a target called ESPLAY-S3 and it used to build and work fine to my knowledge) but I think the current tree doesn't build with esp-idf 5.0+ so that might be a problem.

The changes needed are probably fairly minor, though.

I have been thus far unable to build the esplay-s3 target on ubuntu 23.10, from the main branch or the 1.38.1 tag.

I will keep playing with it, but I'm pretty new to C and ESP32 programming so I'm not really sure I'm understanding what's wrong

My command line is ./rg_tool.py --target esplay-s3 build-img so I'm not sure why it's complaining about odroid-go

I tried using a docker container, installing esp-idf v4.3 per the esp-idf docs, then building retro-go per these docs.

I get similar but different errors, this time about undeclared functions called RTC_SLEEP_PD_*

There was indeed an issue with esplay-s3 not being respected, it's now fixed in the current dev branch.

But to get a successful S3 build you will need esp-idf 5.0 (I think 4.4 maybe had early S3 support too?).

Following those steps in esp-idf 5.0 I get a successful build:

1. Pull my recent changes and switch to the dev branch
2. In components/retro-go/CMakeLists.txt near the top you need to comment the first COMPONENT_REQUIRES line and uncomment the second one.
3. Build with rg_tool.py --target=esplay-s3 --no-networking launcher
4. You'll get several warnings but they can be ignored.

We'll track this issue at #98
