Hello,
I have a board: LilyGo T-Internet-COM
https://lilygo.cc/products/t-internet-com
It has a ESP32 WROVER-E chip and PSRAM (8 MB)
=======================
So I tried the available generated envelope (I have installed version 168):
https://github.com/toitlang/envelopes/releases/download/v2.0.0-alpha.168/firmware-esp32-eth-clk-out0-spiram.envelope.gz
jag flash firmware-esp32-eth-clk-out0-spiram.envelope.gz
This ^^^ seems to be good at first sight, but not working (and not work the others too: firmware-esp32-eth-clk-out0.envelope.gz, firmware-esp32-eth-clk-out17-spiram.envelope.gz, firmware-esp32-eth-clk-out17.envelope.gz)
=======================
So if I check the board github repo, linked from the official product page (link above):
https://github.com/Xinyuan-LilyGO/T-Internet-COM/blob/main/example/ESP-IDF/eth2ap/sdkconfig
From this sdkconfig file these lines seems to be relevant: (2000 char limit ...)

I can figure out things to this point only.
I'm a very beginner, please bear with me.
My goal to use a buyable esp32 board with built-in ethernet and maybe disable wifi (at boot).
Can you give me any guidance where to go from here?
May be I have to create a custom envelope variant with some of the sdkconfig settings above?
Or buy an another board that works with the available variants here (https://github.com/toitlang/envelopes/tree/main/variants), if so, where/what to buy?
Thanks,
Adam

Let's see if we can get the board working.
As you said; we might need a new envelope.

From what I can see, the board uses a lan8720.

- power = 4

If that doesn't work we might need to debug a bit more, but I would be surprised if we can't get the board working.
Adam 12/06/2024 04:23 PM
Wow, works perfectly. Thanks.
For some reason I thought that if wifi is in firmware then ethernet should be too.
I thought that working with containers (with jag) need working network established by the firmware.
This is more simpler for me as beginner.

Great news.
It could be that Jaguar is still trying to open the WiFi, though.
Note that Artemis is fine with just ethernet.

floitsch 12/06/2024 04:29 PM
Not important but maybe interesting: Jaguar itself is just a container and is responsible for opening the WiFi connection. So fundamentally there isn't any "firmware establishes the connection". It's just that

Thanks for the clarification!

"The containers are developed and maintained independently from each other and the virtual machine provides the capabilities for safely running your platform-independent applications, services, and drivers side-by-side."
For some reaseon I thought that virtual machine can not work with internet -> so firmware establish the net connection.
I will check Artemis.

In general we recommend Jaguar for development (and experimentation) and Artemis for deployment.
That means that Artemis is a more powerful but also a bit more "inconvenient".

esp32-eth-clk-out0 and esp32-eth-clk-out17
A variant for ESP32 boards with Ethernet and a clock output on pin 0/17.
Olimex boards with Ethernet should use this variant. The WROOM versions need esp32-eth-clk-out17 and theWROVER versions need esp32-eth-clk-out0 .

Ooh. Interesting. So it's the out0 with spiram that works?

Try the one with spiram then

Perfect. You are using the envelope I wanted you to use.

Yes. Works like a charm.

The Toit platform automatically uses the SPIRAM so you just have more memory available
