Hi All,
I made a simple sample to do test a serial port.
But, there is a compile error due to can’t find le_tty.api’s components.
where can i find and use le_tty.api? It wasn’t included in the Legato AF 16.10.1.(or 16.10.3).
Thanks in advance,
Chase
le_tty is a built-in part of the framework, so you shouldn’t need any “requires api” in your Component.cdef nor do you need to define any bindings in your .adef in order to use it.
Hi Dfrey,
Thanks for the reply.
But, there is a compile error even though I didn’t define any ‘requires api’ and bindings in my Component.cdef and .adef.
Could you review the error message below?

I mean I’d like to test a le_tty_xxx APIs.
Could you let me know how to do it?
Thanks in advance,

Do you have a built version of Legato and a LEGATO_ROOT environment variable set?
What does a built version of Legato mean?
Do you mean the version of mangOH’s Legato? Or, a Legato AF version of host PC?
LEGATO_ROOT environment variable is defined.
I can make exe of my sample app now. Thanks for your comment.
There was a crash between build environment.
But, there is a error when I run it in my mangOH board(w/ WP7504) as below.
Could you let me know how to resolve this error?
Hi Chase ,
If it is possible , Can you please share your Application files.
I suspect , This to be related build environment.
Linking of this Runtime Library is not success .
Please check if your legato build is successful
Before building Application , build legato framework and check.
Also check for the symbol in nm -D libComponent_ttyTestComponent.so , if its listing all API’s as

Hi Chase ,
I tried reproducing the issue , but it worked fine for me.
I suspect this to be related to build issues of Legato Framework
Please follow the below steps
1.Download the source for legato
http://legato.io/legato-docs/latest/aboutReleaseInfo.html
2.Make Sure you have toolchain for wp750x
3.run make wp750x on your legato root.
4.After build is successfull set environment using
./bin/legs
5.Go to your application folder and build your app with mkapp tool
cd apps/sample/ttyTest/
mkapp -t wp750x ttyTest.adef
6.Install your Application using instapp tool
instapp ttyTest.wp750x.update 192.168.2.2
Secondly , there was one issue in the application
As your are trying to open /dev/ttyS0 (in my case Console on target is /dev/ttyHS0)
add that to your .adef as below
requires:
{
device:
{
[rw] /dev/ttyHS0 /dev/ttyHS0
}
}
I made the above changes in .adef before building application .
as it was not able to open the device path (though it existed)
I can see below logs of test cases execution
5. I can see below logs
Jan 6 02:40:29 swi-mdm9x15 user.warn kernel: [ 1690.436166] msm_serial_hs: Rx break

Jan 6 02:40:29 swi-mdm9x15 user.info Legato: INFO | supervisor[461]/supervisor T=main | apps.c DeactivateAppContainer() 340 | Application ‘ttyTest’ has stopped
If build environment is proper , i think this will solve the issue.

Ankita
Hi Ankita,
Thanks for your kindly reply.
I have modified my environment as your recommendation.
make wp750x on my legato root
./bin/legs
build app with mkapp tool

How to resolve it?
Thanks in advance,

Hi Chase ,
I can’t see tty API’s in Legato 16.07.0
You can check available API’s here
http://legato.io/legato-docs/16_07/c_APIs.html
It is good to check the available API’s in each release .
You can view supported APIs here
http://legato.io/legato-docs/latest/aboutReleaseInfo.html
User Docs ->API Guides ->C Runtime Library
I would suggest you to use Latest Legato Framework for Wp series / Legato Version 16.10.1
Regards
Ankita
Hi Ankita,
Could you send the toolchain v16.10.1? or, Could you let me know where can I download it?
Because, I can’t download it from the sierra link below.(it’s gone.)
https://source.sierrawireless.com/resources/legato/downloads/
Thanks in advance,
Chase
Hi Chase ,
You can also use legato-spm to download package
Please follow the steps in this link
Regards
Ankita
Hi Ankita,
Thanks, but it is not the toolchain.
Could you please recheck it? I want to download the toolchain begin as “poky-swi-ext…”.
And, I have one more question.
Could you let me know the Legato version of your mangOH?
It is 16.07.0_xxxxxxxxx_modified in my case.
Thanks in advance,
Chase
Hi Chase ,
I posted the link for Legato Framework only. (i.e atest SDK version for WP85 module (and update legato.sdk.latest link))
You can download full package , just follow these steps .
https://source.sierrawireless.com/resources/airprime/software/legato_spm/
Install latest PDK version for WP85 module (including Legato Source code distribution package)
The following packages will be installed
I am using Legato 16.10.1
Regards
Ankita
Hi Ankita,
I already have installed all packages and I need the toolchain v16.10.1 only.
When I try to download it from the site below, there is an error.
https://source.sierrawireless.com/resources/legato/downloads/
Thanks in advance,
Chase
Hi Chase ,
I checked https://source.sierrawireless.com/resources/legato/downloads/.
I can see the link expired .
So i would suggest , the best way you can get tool-chain is through legato-spm.
Regards
Ankita
Hi Ankita,
I see.
Thanks for your kindly reply.
