Are your tests set up to only use specific test boards with a specific arm-probe config file (device tags?), or are you generating the config file somehow for each test? At the moment, in LAVA we're passing the appropriate /dev/ttyACMx device node into the LXC as we start things up. That's clearly not going to scale here once you're wanting to use more than one AEP in a single test. So, I'm working on this right now. *Hopefully* I'll be able to replicate the /dev/serial/by-id paths - I'll update you shortly. >> I don't catch why the config file is insane and how this will help for >> this problem > >If the config file is to be generated for each test job, the syntax is >awkward to handle as it would need a line inserted instead of >supporting a parser or similar. *nod* IMHO this is not a great design for the config file, but let's see what we can do. ... >>> Note also that physically fitting more AEPs will involve work by the >>> LAB team - especially for devices like the panda, because the power >>> connector which comes with the AEP does not fit the panda and a >>> one-off daughter board is required. >> >> This is something that has been already handled and in the case of the >> mt8173evb everything is already done and working on our server with >> current arm-probe, AEPs and workload automation OK, cool.
