<html><body><div>Hi, <span class="body-text-content">Bjørn<br><br> Thanks a lot for your kind help and reminding. The backport kernel compilation failed due to it's not a vanilla kernel, it already got some function backported from 3.x. So we see some redefinition error.<br><br> I commented out some lines in the file and got the compat.ko /usbnet.ko / cdc-wdm.ko/ qmi_wwan.ko<br> compiled and loaded on the target system.<br><br> I am now playing with the modeswitch, /dev/cdc-wdm0 has appeared. Does it mean the device is ready and I can get a qmi-cli/uqmi talk to it ? Do I have to get something like /dev/qmi_wwan appear in the system ?<br><br>BRs, Jiang Pin ( Richard )<br></span></div><div><br>2015年8月11日 上午12:31，Bjørn Mork <bjorn@mork.no> 写道：<br><div><blockquote type="cite"><div class="msg-quote"><div class="_stretch"><span class="body-text-content"><span class="body-text-content">蒋品 <<a href="mailto:jiang.pin@icloud.com" data-mce-href="mailto:jiang.pin@icloud.com">jiang.pin@icloud.com</a>> writes:<br><br></span></span><blockquote class="quoted-plain-text" type="cite">I wonder if it is possible to backport the qmi driver to linux 2.6.32?</blockquote><span class="body-text-content"><span class="body-text-content"><br>It is.
