MC7430 QMI SDK problem


#1

I recently encountered this problem with mc7430.

Linuxd QMI drivers:S2.34N2.53
SDK: SLQS04.00.15

The driver generate qcqmi0 and qcqmi1
GobiNet : RawIP mode

It show messages as below while I run the sample code Connection_Manager.
/bin/connectionmgrmipsel /bin/slqssdk 0

SWI API: SDK process startup failed
Failed to start SDK : Exiting App
Failure Code : 2

I don’t know what went wrong, I hope to get answers.

Thanks.

@Loo,

Can you see what the attirbutes of both the /dev/qcqmi interfaces and the SDK (slqssdk) file itself are for the user that is currently logged in i.e. ls -l?

Regards

Matt

@mlw,

What did I do wrong? I couldn’t start SDK.

Regards


#6

@Looo,

Not sure why the SDK is not running, do you know if it is built correctly for your system, i.e. some systems need slightly different command sets which means it needs to be rebuilt for the system tool chain.

Regards

Matt


#7

@mlw
thank you for your reply.
My tool tool chain is mipsel-74kc-linux-gnu. I am currently using sdk: SLQS04.00.15.bin\build\bin\mipsel\slqssdk.
The program used is :SLQS04.00.15.bin\SampleApps\Connection_Manager\bin\connectionmgrmipsel
Do I need to provide a toolchain for sierra wireless to recompile a sdk for me?

Regards


#8

@Loo,

If you want a specific build to be generated then yes you will need us to rebuild it for you with your toolchain. You are going to need to push this back through your distributor to do this.

Regards

Matt
