redSensorToCloud won't start

mangOH Red
1

Am heading through the MangOH Getting Started document and all is going well until I try to start the redSensorToCloud app to verify data is getting to AirVantage.

root@swi-mdm9x28:~# app start redSensorToCloud
There was an error.  Application 'redSensorToCloud' could not be started.
Check the system log for error messages.

Looking at the system log I see the following:

I think the root cause is due the LED file not being found. Is there a step in building the environment I need to re-do?

TIA

Which Legato version are you building against? Are you building the latest mangOH code? You’re right that RedSensorToCloud is failing because of the LED file. Is the LED kernel module referenced in the kernelModules section of the SDEF you are building your system from?

Sorry in advance if I don’t have all the components straight in my head yet, but I’m using this firmware SWI9X07Y_02.16.02.00 / 002.032_000 and 18.04.0 for the Legato framework, IIUC. The README.md’s don’t seem have have version numbers, but everything I’ve installed I’ve downloaded from the Getting Started guide in the last 2 days.

Here is the kernelModules in ~/mangOH/mangOH.sdef which does reference the LED.

kernelModules:
{
#if ${MANGOH_BOARD} = RED
    // $MANGOH_ROOT/linux_kernel_modules/mangoh/9-mangoh_red_dv2
    // $MANGOH_ROOT/linux_kernel_modules/mangoh/9-mangoh_red_dv3
    $MANGOH_ROOT/linux_kernel_modules/mangoh/9-mangoh_red_dv5

    // USB to SPI adapter connected to the mt7697 and RPi header
    $MANGOH_ROOT/linux_kernel_modules/cp2130/0-cp2130

    // temperature and pressure sensor
    $MANGOH_ROOT/linux_kernel_modules/bmp280/2-bmp280
    $MANGOH_ROOT/linux_kernel_modules/bmp280/3-bmp280-i2c

    // accelerometer on DV3 and later board revs
    $MANGOH_ROOT/linux_kernel_modules/bmi160/3-bmi160
    $MANGOH_ROOT/linux_kernel_modules/bmi160/4-bmi160-i2c

    // $MANGOH_ROOT/linux_kernel_modules/lsm6ds3/1-lsm6ds3-i2c

    // battery gauge
    $MANGOH_ROOT/linux_kernel_modules/ltc294x/0-ltc294x.mdef

    // battery charger

    // LED on GPIO driver

Any other advice on this David?

Hello, same issue here…any updates?

Hello, still have this problem. Any solutions out there?

8

Sorry, I’ve been busy on another project so haven’t been able to get back to this. My next step was to try to comment out the line:
$MANGOH_ROOT/linux_kernel_modules/led/0-led

in ~/mangOH/mangOH.sdef nd then see if that worked. Have you tried that? I haven’t gotten to try that yet.

Has anyone resolved this issue? I’m having the same issue with a 7702 and haven’t heard any feedback. My thread is here
