Hi Neil,

thanks for the quick reply. How do you simulate hot plugging in your lab then?

No, it is not.

Hi Neil,

thanks for the quick reply. How do you simulate hot plugging in your lab then?

For a few devices which need the OTG to be disconnected during test jobs, we can use a Cambrionix PP15S - that can also do power control for a few devices which only have USB power, like IoT.

https://www.cambrionix.com/products/powerpad15s-pp15s/

For devices which have jumpers to get into and out of recovery mode, we use dedicated relay boards.

Other than that, hot plugging is not automated.

https://linux.codehelp.co.uk/the-problem-of-sd-mux.html

There is another SD mux type unit in testing at the moment but it's not widely available.

I'm testing SDWire (https://wiki.tizen.org/SDWire). It seems to work with RPi for example. It doesn't work with all boards I tried, so it's more try-and-error thing. As for LAVA part it can be used with 'flasher'. The support isn't ideal as it doesn't do proper rollback in case job times out at some point (you need to make sure dd doesn't time out). But for my use case it's good enough.
