firmware update

[dailijin]

Hi David,


Thanks your share about firmware updating. it is very useful.


If I only upload GobiNet, GobiSerial driver, and disable qmi_wwan driver, I think finally I can successfully update firmware via Sierra SDK (though sometimes still update firmware fail now). 


my usage is simultaneity use several MC7354 modems on Ubuntu system, I should firstly login the system via one modem's network, then do modem firmware update, if directly disable qmi_wwan, all modems can't work,
and I also can't login the system.  so this is why I want to need libqmi to do that.


I reviewed all above emails, this seems is not easy request. I think I should find a workaround to solve this issue before libqmi completely do that, could you give me some suggests?

Thanks
