Hi,
I have downloaded and compiled/installed (on Ubuntu 12.04 the arm-probe
from: https://git.linaro.org/gitweb?p=tools/arm-probe.git;a=tree
Now I am facing some issues using the tool. My Arm Energy Probe shows up
as virtual serial port as /dev/ttyACM0 and I am able to open that port via “
# sudo screen /dev/ttyACM0
and when I “ctrl-c” in screen I get a response from the energy probe
saying “ARM Energy Probe”. So the probe should be working fine.
If I however run
# arm-probe –c ch1
All it just shows is the blelow, there are no data streamed out at all:
# configuration: ./config
# config_name: K70-SOM
# trigger: 0.400000V (hyst 0.200000V) 0.000000W (hyst 0.200000W) 400us
Configuration: K70-SOM
# date: Fri, 24 May 2013 15:45:57 +0200
# host: rb
#
This is the content of my configuration file:
# arm-probe configuration file
#
# setup name
K70-SOM
/dev/ttyACM0
ch1 0.470 1 -0.000253 0 VCORE1/MPU
ch2 0.470 2 -0.000253 0 VCORE1/MPU
ch3 0.470 3 -0.000253 0 VCORE1/MPU
Have you tried using the config file here?
https://git.linaro.org/gitweb?p=tools/arm-probe.git;a=blob;f=config;h=2daed868003999ec3da619a4b0ebc9b4c11b6b6f;hb=HEAD
It changed recently to use /dev/serial/by-id/... and instead of polling
for AEPs just collect all the ones mentioned.
