<p class="MsoNormal"><span lang="FI">Hello,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="FI"><o:p> </o:p></span></p>
<p class="MsoNormal">I am using a custom Linux board with kernel version 4.9 and qmicli version 1.22.0. I have used a MC7304 for two years with no problems.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have now tried updating to both a MC7455 and MC7430. Initially neither worked, every qmicli command I made resulted in a “transaction timed out” message.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I then updated both qmi_wwan.c and qcserial.c to the latest version (from kernel 5.0-rc8). MC7430 started working, but MC7455 still does not work. For example trying to change the data format looks like this:<o:p></o:p></p>
<p class="MsoNormal">qmicli -d /dev/cdc-wdm0 --wda-set-data-format=802-3<o:p></o:p></p>
<p class="MsoNormal">error: couldn't create client for the 'wda' service: CID allocation failed in the CTL client: Transaction timed out<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I can get the modem to respond to QMI messages using the GobiNet and GobiSerial drivers provided by sierra Wireless, but I really don’t want to develop my own cli using those drivers, I’d much rather continue using qmicli.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anyone have any ideas?<o:p></o:p></p>
