Ethernet ENC28j60 github example - Error: enc28j60_init: wrong chip ID

[KeshavThosar]

After running idf.py menuconfig and flashing the code, I am getting a “Wrong Chip ID” error. I explored the code and I think the problem seems to be occurring while reading the PHY register PHCON1 (ETH_PHY_IDR1_REG_ADDR) and PHCON2 (ETH_PHY_IDR1_REG_ADDR). My wiring is functioning properly but the issue is persistent.

As a check I tried printing out the id1.val and id2.val but both ended up being 0 (hence my assumption). Any help would be appreciated. Thanks

The pins set up in sdkconfig

My wiring is functioning properly

Just curious: what makes you so sure about that?

My wiring is functioning properly

Just curious: what makes you so sure about that?

It is because when I tested it initially, it failed to retrieve the revision ID (so it was just assigned 0) so I re-did the wiring, and then it worked out (Later it gave me a value of 6 and kept doing so).

[KeshavThosar]

So it seems I messed up the wiring and the clock speed. I reduced the length of the jumper wires and reduced the SCK speed to 6MHz and it is functioning now. Hope this helps. Thanks to ESP-Sprite for bringing in the thought.

[ESP_Sprite]

Heh, you're welcome, glad you got it working.

[Ankit24011995]

I am also having the same issue.
I made a PCB of ESP32 and ENC28J60 which is working with Arduino IDE. But on the same PCB its not working with idf.
Please help.

[David64]

I faced similar kind of issue last time, I am still searching for some proper solution!!
