CM3+custom board+last strecth+firmware 4.14.61-v7 #2650

Open JTrotta opened 6 years ago

JTrotta commented 6 years ago

I'm using a custom board with CM3, with two smcs9514 chip connected together. Since last week I'm facing with the following problem: Aug 13 07:26:09 raspberrypi kernel: [ 143.547999] usb 1-1.5-port1: disabled by hub (EMI?), re-enabling...

The smsc9414 is disconnected and reconnected several times, then, after few seconds the CPU freeze, and must be un-powered and re-powered. This happen in my car, when I power the board using the car battery. The strange things is that in my office, with an external power unit, everything works fine for weeks. Any hints? JJ

pelwell commented 6 years ago

I suspect the problem is caused by power fluctuations or EM interference - the USB driver certainly thinks so:

usb 1-1.5-port1: disabled by hub (EMI?)

Try a different power source (at least as a trial), shielding the unit, etc.

JTrotta commented 6 years ago

@pelwell I was wondering if the (EMI?) hints is a real cause , or just a suspicion by the code writers. I mean is the driver capable to check different causes or just suggest one for all?

pelwell commented 6 years ago

It's probably just suspicion, but that doesn't really change anything - you've shown that an environmental factor is affecting performance, so now you have to work through the differences to work out which one was significant in this case. On a regular Pi vcgencmd get_throttled would show you if undervoltage has been detected, but that isn't usually an option on a CM carrier so you'll need some other way of measuring the supply rail voltages under load.

gnulux commented 4 years ago

Hi, Did you solve this problem ? I've encountered the same behavior with a Raspberry 3 . Wondering if this is really related to power supply or if could be a simple driver bug ? Ramdomly , i loose the network interface on this remote device. The only choice i have is to ask my customer to power off/on.

Have you tried using the upstream dwc2 driver instead? Put dtoverlay=dwc2,dr_mode=host.
