enc28j60 random disconnects #3702

Open ComexioDev opened 4 years ago

ComexioDev commented 4 years ago

Describe the bug I use a enc28j60 ethernet module with spi on my CM3+. Sometimes it randomly disconnects (about once every day) with following error (dmesg): eth0 (enc28j60): transmit queue 0 timed out

To reproduce

Additional context I tested it with the current stable kernel and i testet it with the new kernel. Both have the same Problem. While i was searching i found a forum post https://www.raspberrypi.org/forums/viewtopic.php?t=232969. It doesn't contain any answer and no link to any bugreport.

I hope this is the right way of reporting this and i am sorry for any inconvenience. Feel free to correct me or ask for any additional information.

pelwell commented 4 years ago

I have been unable to reproduce the "transmit queue 0 timed out" failure, which makes it hard to diagnose.

ComexioDev commented 4 years ago

Can i give you any additional information to help you reproduce?

pelwell commented 4 years ago

That's so hard to say - you have given a fairly full, clear report. Perhaps you could say something about the other hardware attached?

As you can see, i use spi and i²c.

The enc28j60 int_pin is wired to pin 35, so i had to modify the gpio35-39 overlay to take pin 40 instead of pin 35.

pelwell commented 4 years ago

The touchScreen overlay isn't a standard one - what's in it, or at least how is the touchscreen device attached?

ComexioDev commented 4 years ago

Its a Focaltech touchscreen with the following overlay, connected with i²c on GPIO 44-45:

FD- commented 3 years ago

I'm seeing the same problem.

Similar to @ComexioDev I also have additional devices attached to the Pi: I have 3 devices on the I2C bus and am using both SPI interfaces (one to an STM32 and one to the ENC28J60). All of them are running off the Pi's 3v3 rail, so maybe high strain on that rail could play a role?

I'm on a Pi 3A+ using a 4.19.97 kernel (newest Raspbian Lite image when obtained from the official website back in March).

I was also seeing the same issue with a Zero 2 W. The timeouts were occuring when enc28j60's interrupt was triggered off by a program using switching the same pin low (GPIO 25 in my case).

I tried both enc28j60 and w5500 on a Raspberry Zero 2W with latest Raspberry Pi OS (bookworm). Both seem to show this issue (latest updates applied, 6.1.0-rpi7-rpi-v8 #1 SMP PREEMPT Debian 1:6.1.63-1+rpt1 (2023-11-24) aarch64 GNU/Linux). I can easily reproduce it by sending pings in a timely manner.

mtr -i 0.5 -s 1400 -n -o "LSRD NBAW X" hostonmynetwork

When executing with lower/higher intervals(-i) the issue is harder to reproduce or doesn't happen at all.
