Can not get ethernet working in olimex ESP32-EVB rev C board #239
Description
I've read the closed issue #172 where smeedy got the ethernet working in a ESP32-GATEWAY board from same vendor.
The PHY and GPIOs used are the same in both boards but in mine, following the same steps I'm unable to get the ethernet working (MicroPython v1.9.2-445-g84035f0f on 2017-12-06; ESP32 module with ESP32)
The sequence used is:
>>> import machine
>>> import network
>>> l = network.LAN(mdc = machine.Pin(23), mdio = machine.Pin(18), power = machine.Pin(17), phy_type = network.PHY_LAN8720, phy_addr=0)
I (205443) emac: mac version 1137a
>>> l.ifconfig()
('0.0.0.0', '0.0.0.0', '0.0.0.0', '0.0.0.0')
>>> l.active(1)
I (960717) emac: emac start !!!
I (960717) emac: emac resetting ....

Hi Patxitron,
I just know the Problem from the c sdk esp-idf. There was a commit espressif/esp-idf@22ae5ad that should have fixed the issue, maybe the same can be applyed to the micropython repo.
But for me the Problem still exist. Replugging the USB cable resolves the issue.

MicroPython was today updated to the latest ESP IDF, see micropython/micropython@c49a73a. This includes the fix mentioned above, so it might work now.

I've also read the closed issue #172.
I don't understand how can I do a "make monitor".
I am on Windows environnement and when I test this code:
I have this result:
For information I use a ESP32-Gateway Rec C board.
Thank you for your help.

Try with mdc = machine.Pin(23), mdio = machine.Pin(18), power = machine.Pin(17), phy_type = network.PHY_LAN8720, phy_addr=0

Yes in fact in my example I put another tested line.
But with this command it is the same result.
