Ledservice bind no <root>.ma_led

On MangOH red :

Firmware Version:              SWI9X06Y_02.32.02.00 c2e98c jenkins 2019/08/30 07:28:21
Bootloader Version:            SWI9X06Y_02.32.02.00 c2e98c jenkins 2019/08/30 07:28:21
legato version    20.04.0_73c525f681f777a978c4e5500b796c47

I use the leaf profile mangoh-red-wp77xx_06.0 package for the cross compilation on my ubuntu 20.04.

I’ve make a simple program to blink the led with de api ledservice ( my .adef )

components:
{
}
executables:
{
    wClientExe = ( wClient )
}
start: manual
processes:
{
    run:
    {
        ( wClientExe )
    }
}
bindings:
{
    wClientExe.wClient.ma_led   -> ledService.ma_led
}

I’ve make a .sdef to be sure to have the ledservice

#include $LEGATO_ROOT/default.sdef
g any other sections.
buildVars:
{
    // Define a base directory for your project.
    MY_SYSTEM_DIR = $CURDIR
}
interfaceSearch:
{
    // Your project's search paths.
    ${MY_SYSTEM_DIR}/interfaces

    // Legato API search paths.
    ${LEGATO_ROOT}/interfaces
    ${LEGATO_ROOT}/interfaces/airVantage
    ${LEGATO_ROOT}/interfaces/atServices
    ${LEGATO_ROOT}/interfaces/logDaemon
    ${LEGATO_ROOT}/interfaces/modemServices
    ${LEGATO_ROOT}/interfaces/portService
    ${LEGATO_ROOT}/interfaces/positioning
    ${LEGATO_ROOT}/interfaces/secureStorage
    ${LEGATO_ROOT}/interfaces/wifi
}

appSearch:
{
    ${MY_SYSTEM_DIR}/apps
    ${MY_SYSTEM_DIR}/mangOH/apps/LedService/
}

// Directories where components are searched.
componentSearch:
{
    ${MY_SYSTEM_DIR}/components
}

moduleSearch:
{
    ${MY_SYSTEM_DIR}/modules
}

apps:
{
    wClient
    ledService
}

But my program have lots errors when i start it
When i remove the led api, it work fine

The problem seems to be that the ma_led not present, the sdir list | grep ma_led return

wClient.wClientExe.wClient.ma_led -> <root>.ma_led
[pid  1734] wClient.wClientExe.wClient.ma_led WAITING for <root>.ma_led  (protocol ID = '3dd2be270c89a5a489f7b63c8ff381b3')

So where my problem ?

Thanks

How about change to one of the followings in your simple program adef file?

Test1:

bindings:
{
wClientExe.wClient.ma_led -> ledService.ledServiceComponent.ma_led
}

Test2:

bindings:
{
wClientExe.wClient.ma_led -> ledService.ledService.ledServiceComponent.ma_led
}

Hello

I found a solution, but why now it work, it’s a mystery !

I change my leaf profile :

  • swi-vscode-support: 200624
  • swi-wp77: 3.4.0 ( not the mangoh-red-wp77xx_06.0 package !)

I build from scratch de mangOH git ( GitHub - mangOH/mangOH: Primary mangOH git repository ), and update my board.

And miraculously, the line in “sdir” appeared :

root@swi-mdm9x28-wp:~# sdir list | grep led
<root>.ma_led (protocol ID = ‘3dd2be270c89a5a489f7b63c8ff381b3’, max message size = 16 bytes)

I modify my .adef file, with this bindings:

bindings:
{
wClientExe.wClient.ma_led → <root>.ma_led
}

And, now it don’t crash on app start !
