MC7430 modem issue

Tue Dec 29 19:31:30 PST 2015

Hi Markus,

I completely use the qmi_wwan driver source code from http://lists.freedesktop.org/archives/libqmi-devel/attachments/20150702/f35f05a0/attachment.obj, the issue back to that the device can't respond QMI command now.
if I also merge the patch, compile also fail. Right?

I noticed libqmi added some changes for MC7455 modem yesterday, and I know the MC7430 and MC7455  based on 9X30, so they are similar, if MC7455 can't work via libqmi now, the MC7430 should also can't work via libqmi till now. Am I right?

If anyone have made MC7430 or MC7455  worked now. I appreciate you very much if you can share the method.

Note:
   My host is  Intel x86_64,  system and kernel is gentoo + ubuntu's kernel 3.8.0-23-generic

Thanks

I check the data format which is 'raw-ip', and can't be changed via qmi command, this maybe why I can't get IP. because I remember MC7304 and MC7354  can work before only after I set '802-3' as data format for them.
