Cerbo: ftdi usb issue at power up (?) and not recovered #621

Closed mpvader closed 4 years ago

mpvader commented 4 years ago

On Lucian his system: https://vrm.victronenergy.com/installation/47448/overview

the grid meter is connected to the missing ftdi usb.

Venus OS v2.53

and there is another ftdi usb rs485 interface, connected to the IMT meteorological sensor - which díd survive the boot and was working properly.

dmesg output below. At [168309.247999], the ftdi cable was unplugged and replugged by lucian. Before, and after, that, the leds on it were blinking.

Mans looked into it.

Looks like the FTDI converter got itself into some weird state. the kernel was trying and failing to reconnect; it tried all, including power cycling the usb port (see the logs). Note that the FTDI was connected to an external hub, so might be that that doesn't support power cycling its ports.

The ports on the Cerbo should support that as per schematics and hardware, but we never verified that.

The one other thing the Cerbo cq 'we' could have done is power cycle the complete Venus OS.

Anyway, for now closing this - we'll continue when this happens more.

Two other things we could do:

another suggestion, making usb issues visible. either for us, on vrm, or even for the customer.

closing this for now, we can always dig it back up if more instances are reported.
