Wired etherent connectivity

Test using Olimex ES32-gateway with Ethernet to be used instead of Wi-Fi when installation is more suited to wired Ethernet

I've just tried to test Ethernet on the Olimex ES32-gateway board, however when I try to compile the openevse_esp32-gateway environment I get Error: The program size (1312862 bytes) is greater than maximum allowed (1310720 bytes)

Have you able to compile the current version for the ES32 gateway board?

Travis CI also showed this issue for some reason, oddly worked fine locally. In any case been meaning to look at the binary size because building the debugger build fails for the same reason.

Given we are not using SPIFFS I opted to just use a different flash partition table to give us an extra 40% space.

Not tried it but I suspect this will not update over OTA.

Thanks, it compiles fine now.

I've just tested updating Huzzah32 via HTTP update via web interface with a .bin compiled with min_spiffs.csv and it worked fine!

I've finally managed to get this up and running, it turns out the silkscreen on my hardware rev C is different to yours! Here are the location of Rx, Tx:

Unfortunately the Ethernet does not seem to be working, I get these errors in the debug serial:

E (2094) emac: Timed out waiting for PHY register 0x2 to have value 0x0007(mask 0xffff). Current value 0xffff
E (3094) emac: Timed out waiting for PHY register 0x3 to have value 0xc0f0(mask 0xfff0). Current value 0xffff

Is a Rev.E on that picture ;-) can you try
platformio_esp32_eth.zip ?
If that does not work, can you try the WiFi->ETH_LAN870 examples from the Arduinio IDE

Ah here is the issue I think: https://github.com/OLIMEX/ESP32-GATEWAY/blob/master/SOFTWARE/Newest-board-revisions/ETH_PHY_demo/main/ethernet_example_main.c#L59

That logic for the power pin is not in the rev B/C sample: https://github.com/OLIMEX/ESP32-GATEWAY/blob/master/SOFTWARE/Hardware-revisions-B-or-C/ETH_PHY_demo/main/ethernet_example_main.c

The Arduino core has a setting for the revision of the board, in Platform IO this is done in platform.ini using:

board_build.extra_flags = "-DARDUINO_ESP32_GATEWAY=\'E\'"

In addition to this there is also (now) a conflict with Serial2 and the Ethernet... GPIO17 is used for both so moved TX2 to GPIO 32 so the pinout is also changed.

Fixed in ef4995d

Awesome, just tested this and it's working :-)
