Once the<br> module knows the required version is one that it doesn't have<br> installed, we trigger a reboot and at this point, the module will<br> accept any kind of new file downloaded.

I can try to patch the source code.<br> ><br> <br> I guess we could extend the qmi-firmware-update operation to say:<br> flash the first CWE+NVU pair found, but also try to flash any<br> additional CWE or NVU file found. I truly have no idea whether that's<br> possible, really. I don't recall all the details of the upgrade<br> process, but I do believe there is a way to select in which slot to<br> flash, and in the newest firehose based modules the upgrade operation<br> also preselects the filename inside the module (e.g. all CWE files<br> would be written as "spkg.cwe", so it could be that even if you're<br> flashing 10 different CWE files only the last one is really<br> considered).<br> <br> > My main goal is to reduce the time of flashing while working with multiple FWs.<br> ><br> <br> Yeah, not sure if the modules themselves are ready for that, or at<br> least we may not have all the necessary info to know how to do that.<br> qmi-firmware-update is mostly based on reverse engineering USB traces<br> generated by other proprietary programs :)<br> <br> > P.S.<br> > Connected email thread: "qmi-firmware-update with multiple NVU for Sierra EM7411".<br> ><br> <br> Here's the link to that thread, for context:<br> <a href="https://lists.freedesktop.org/archives/libqmi-devel/2020-October/003402.html" rel="noreferrer" target="_blank">https://lists.freedesktop.org/archives/libqmi-devel/2020-October/003402.html</a><br> <br> --<br> Aleksander<br> <a href="https://aleksander.es" rel="noreferrer" target="_blank">https://aleksander.es</a><br> </blockquote></div><br clear="all"><div><br></div>-- <br><div dir="ltr" class="gmail_signature"><div dir="ltr">With best regards,<div>Alexander</div></div></div>
