Thanks for looking into this, Neil. I wrote a test definition to build, install, and run the arm-probe command-line tool in LAVA, but I'm running into the error where the probe path cannot be accessed without running into the 'exclusive' error: https://pmwg.validation.linaro.org/scheduler/job/1489#L3776 In a manual setting, I expect to see output similar to this: # configuration: config-panda-lab # config_name: pandaboard # trigger: 0.400000V (hyst 0.200000V) 0.000000W (hyst 0.200000W) 400us Configuration: pandaboard # date: Wed, 26 Apr 2017 22:47:59 +0100 # host: pmwg-server-01.pmwglab # + /dev/serial/by-id/usb-NXP_SEMICOND_ARM_Energy_Probe_S_NO44440001-if00 Starting... sending start to 0 # VDD_ALL VDD ROOT #ff0000 SoC # # time VDD(V) VDD(A) VDD(W) 0.000500 5.19 0.0994 0.51568 0.000600 5.19 0.0704 0.36538 0.000700 5.19 0.0994 0.51538 0.000800 5.19 0.0764 0.39608 0.000900 5.20 0.0654 0.33967 0.001000 5.19 0.0934 0.48444 0.001100 5.19 0.0754 0.39097 0.001200 5.19 0.0734 0.38052 ... ... However, I was able to verify that the LXC detected the probe by writing an inline test definition to use the lsusb command: https://pmwg.validation.linaro.org/scheduler/job/1489#L2049 >> >> As we discussed during our sync, the device dictionary looks correct, >> yet I'm not sure if the probe is detected inside the LXC.
