How to build the bin file of ESP32-S3 WIZNET5K to support Ethernet communication

[yfyungit]

I checked the following links and did not find instructions for building WIZNET5K or custom drivers
https://docs.micropython.org/en/latest/reference/manifest.html

Where can I find the relevant documentation?

I need to build ESP32-S3 16MB and 4MB flash versions to support WIZNET5K Ethernet communication using W5500

[bidrohini]

MicroPython's support for WIZNET5K Ethernet modules is controlled by the MICROPY_PY_NETWORK_WIZNET5K configuration option. You have to enable this.

[projectgus]

This is true for all MicroPython ports that supports Wiznet W5500, except for esp32 port. On esp32 port the driver is part of ESP-IDF (not MicroPython) and is enabled by default on most builds.

(This wasn't documented at the time this question was asked, but it's documented now. Details in other answer.)

@bidrohini After I enabled MICROPY_PY_NETWORK_WIZNET5K support, I got an error during the build process

I just made it work for 1.24.1 / idf 5.2.2 just adding MICROPY_PY_NETWORK_WIZNET5K 1 to ports/esp32/boards/ESP32_GENERIC_S3/sdkconfig.board

[yfyungit]

@littlegreenbean33 Thank you very much. This problem has troubled me for a long time. After following your instructions and building a new firmware, W5500 can work normally now.

[kevinf300p]

I'm a newbie trying to get WIZNET5K/W5500 to work on an ESP32_GENERIC_S3. Been struggling to get WIZNET properly included. when I add MICROPY_PY_NETWORK_WIZNET5K 1 to ports/esp32/boards/ESP32_GENERIC_S3/sdkconfig.board, I get...

/var/folders/8x/tyb23w3j08106x8twvsdft8d3qbsc8/T/kconfgen_tmp38tyg1kr:191: warning: ignoring malformed line 'MICROPY_PY_NETWORK_WIZNET5K 1'

[projectgus]

@kevinf300p The esp32 port uses a different driver for WIZNET5K to some other ports. Setting MICROPY_PY_NETWORK_WIZNET5K shouldn't be necessary, in particular it's not an sdkconfig option and I'd expect to see the same error you're seeing if adding to that file. I'm not sure exactly how the other two posters got this to work.

EDIT: I've put the key info into another post so I could mark it as an answer, see https://github.com/orgs/micropython/discussions/16237#discussioncomment-12608836 (one of the examples is even exactly your hardware setup, ESP32-S3 with W5500).

@littlegreenbean33 During the use, I still have a question: How to use WLAN and W5500 at the same time? For example, WLAN uses TCP to connect to server A, W5500 establishes a TCP server, and waits for the external TCP client to establish a connection. Both connections can be used normally. Can you share your experience or provide a simple demo code for reference?

[littlegreenbean33]

you need to bind the socket to the address of the specific interface. That way you listen on the specific address associated to the specific interface.

Because Micropython/Esp32 do not do (by default) forwarding between the network interfaces, the client and server will only be able to connect to devices in the same network. (i.e. either wifi or LAN)

You need to take of a asynchronous nature of your case. Assuming reading writing to a socket, while at the same time having a server listening on the second interface. Threads,

The esp32 port already supports Wiznet W5500, but it uses a different method to configure it compared to other ports. See newly added docs here: https://docs.micropython.org/en/latest/esp32/quickref.html#spi-ethernet-interface

(These docs weren't there at the time of this question.)

Thank you very much, with relevant documents this will help many people
