AHB versions use it over SMD and without it, AHB support wont work, it will find the HW model and revision and that's it, only after the QRTR_SMD is inserted you can use QMI to load the caldata etc. Regards, Robert > > -- > https://patchwork.kernel.org/project/linux-wireless/list/ > > https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
