Network interface

[untitledlt]

Is it possible to user network interface on this devboard?
From micropython docs:

To use this module, a MicroPython variant/build with network capabilities must be installed. 

I don't see Driver in network module. Does it mean that this micropython port does not include network capabilities?
Thanks!

It's a F407 based board, so it has Ethernet MAC unlike the F405 on the original pyboard.
Haven't implemented it yet though.
If any of the other F407 boards have implemented it, I could try upgrading this board to match.

Maybe try the $4 W5500 module?

Don't think it's worth to use external module if it has built-in support.
How can i help to make it happen faster?

I found these boards defining HW Ethernet via RMII:

But it's not F407

These are the F407 Eth pins:

Try adding this to the bottom of mpconfigboard.h and building.

// Ethernet via RMII
#define MICROPY_HW_ETH_MDC          (pin_C1)

Here's what i'm getting now:

# MicroPython settings
MICROPY_PY_LWIP = 1

In mpconfigboard.mk?

As per:
https://github.com/micropython/micropython/blob/master/ports/stm32/boards/NUCLEO_F429ZI/mpconfigboard.mk

I had to clone micropython with --recursive flag but now i'm stuck with new errors:

My bad. This is the VET6 board, not the ZET6 or ZGT6. There's no G pins on this board. Use the B pins instead.

Try replacing this:

#define MICROPY_HW_ETH_RMII_TX_EN   (pin_G11)
#define MICROPY_HW_ETH_RMII_TXD0    (pin_G13)
#define MICROPY_HW_ETH_RMII_TXD1    (pin_G14)

With this:

#define MICROPY_HW_ETH_RMII_TX_EN   (pin_B11)
#define MICROPY_HW_ETH_RMII_TXD0    (pin_B12)
#define MICROPY_HW_ETH_RMII_TXD1    (pin_B13)

Tried about everything I could find online to get a LAN8720 from Aliexpress to work.
After compiling the board just doesn't seem to work. Green led on ETH port lights up and thats it.

>>> import network
>>> l = network.LAN()
>>> l.active(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: [Errno 110] ETIMEDOUT

I know it's not the module as it works fine on an ESP32 with Micropython
