ESP32-EVB-rev C ethernet not working

patxitron · December 12, 2017, 07:48:23 PM

Recently I bought an ESP32-EVB board. I'm trying to use the wired network. First I tryed using micropython using the same commands used in the las post of this issue https://github.com/micropython/micropython-esp32/issues/172 but in my board this result on two errors repeating continuosly:

Code Select


E (961727) emac: Timed out waiting for PHY register 0x2 to have value 0x0007 (mask 0xffff). Current value 0xffff
E (962727) emac: Timed out waiting for PHY register 0x3 to have value 0xc0f0 (mask 0xfff0). Current value 0xffff

Today I'm trying to do it using arduino code. I've got the blink example working with one of the relays, but when I try to execute the ETH_LAN8720 example, it outputs the same two errors as in the micropython case.

Is there any efuse or setup I'm skipping in order to get the ethernet working? Maybe I need to configure a MAC address? How?

Thank you in advance and best regards.

Hello,

Why don't you start with our ESP-IDF example here: https://github.com/OLIMEX/ESP32-EVB/tree/master/SOFTWARE ? If you get "emac: emac rx buf err!" error the workaround are described in this forum thread: https://www.olimex.com/forum/index.php?topic=5891.0 and also here: https://github.com/OLIMEX/ESP32-EVB/issues/11

In the official Arduino for ESP32 (https://github.com/espressif/arduino-esp32) make sure after installation to select the ESP32-EVB board in the board manager.

Best regards,

Same errors, captured after flashing and reseting:

I guess I need to clarify one thing: My previous post is using your ESP-IDF example.

Best regards.

LubOlimex · December 19, 2017, 04:15:45 PM

Hey,

Can you share a picture of your hardware setup - Ethernet cables, board, etc

I feel like it might be too long or faulty Ethernet cable. The only similar thing that I found was this: https://github.com/espressif/arduino-esp32/issues/744

Best regards,
Lub/OLIMEX

patxitron · December 21, 2017, 06:25:07 PM

Ok, I solved it. Still I don't know exactly how I have it done, but playing in the gtkterm with the DTR and RTS signals I have it working now.

Best regards.

meyer · January 19, 2018, 04:34:09 PM

Hello,

I have exact the same problem on win10, using actual esp-idf ethernet example with ESP32-OVB Rev C.
Settings:
CONFIG_PHY_TLK110=
CONFIG_PHY_LAN8720=y
CONFIG_PHY_ADDRESS=0
CONFIG_PHY_CLOCK_GPIO0_IN=y
CONFIG_PHY_CLOCK_GPIO0_OUT=
CONFIG_PHY_CLOCK_GPIO16_OUT=
CONFIG_PHY_CLOCK_GPIO17_OUT=
CONFIG_PHY_CLOCK_MODE=0
CONFIG_PHY_USE_POWER_PIN=
CONFIG_PHY_SMI_MDC_PIN=23
CONFIG_PHY_SMI_MDIO_PIN=18

Have installed the drvier from olimex. Flashing works as expected, but when running I get this error:

I (294) emac: emac start !!!

I (294) emac: emac reset done
E (1304) emac: Timed out waiting for PHY register 0x2 to have value 0x0007 (mask 0xffff). Current value 0xffff

E (3304) emac: Timed out waiting for PHY register 0x2 to have value 0x0007 (mask 0xffff). Current value 0xffff
E (4304) emac: Timed out waiting for PHY register 0x3 to have value 0xc0f0 (mask 0xfff0). Current value 0xffff
E (5304) emac: Timed out waiting for PHY register 0x2 to have value 0x0007 (mask 0xffff). Current value 0xffff

Also tried other valus for CONFIG_PHY_CLOCK

best regards, Frank

meyer · January 19, 2018, 05:13:09 PM

Solved it by using another usb port. It seems the one didnt have enough power.

Skippy · January 27, 2018, 02:34:06 AM

I have a very similar problem. At first I had the problem as described above, which I fixed by putting a powered USB hub between the computer and the board. It also works if I used my laptop rather than my desktop.

Now I get:

and like that for ever. It never gets an IP address. The link lights are on, and I've tried different cables. Any ideas how I can get it to work?

Skippy · January 27, 2018, 10:45:48 AM

Also I tried an external power supply with no improvements

Skippy · January 27, 2018, 03:47:39 PM

I've solved my own problem, as it says elsewhere on this forum the version of this example program that comes with the Espressif IDF devkit works, the one on olimex's github doesn't.

emiguns · May 02, 2018, 07:57:01 PM

Hi, my name is Emilio,
Could someone help me solve the problem of the mistake Emac timed out of PHY etc etc?
I am not very good at the card program evb-revC and use some samples with the IDE of Arduino.
Sometimes the board works properly and sometimes not.
I used a usb cable or a proper power supply but it is still same problem.
Greetings.
