I almost have stock Debian 13 booting on this DragonBoard 410c with U-Boot, firmware is the issue. I would like to revisit PostmarketOS on it too. It's a really interesting little board - the worst thing about it is the size of the RAM. I can work within that though. I need to figure out how to add more packages to Postmarket OS though.

#debian #linux #postmarketos #dragonboard410c

I have the firmware - I just need to figure out how to load it. Supposedly Debian ARM64 has the WiFi firmware - it's in the Dragonboard 845 firmware in the repo - built in and I can get all the drivers I need elsewhere. It just isn't loading the WCN3620 firmware when I ask the installer to.

@kelpana iirc it should be part of linux-firmware, maybe some subpackage is missing?

The msm8916-mainline matrix channel has folks who I'm sure would be able to help answer some questions.

Out of curiosity, are you running upstream U-Boot?

@cas Thanks. I am using U-Boot v2026.01 that I built myself for the db410c, following the documentation on the U-Boot website. and I found the msm8916-mainline kernel and built it, but I haven't tried using that yet. I have the firmware support packages from Qualcomm (https://builds.96boards.org/dragonboard410c/qualcomm/firmware/), so it should just be as simple as uploading them to the chips, just Debian installer is refusing to recognise the WiFi chip on the board even though I appear to be choosing the correct driver.
@kelpana iirc you might need to set the mac address for the wifi chip, there's a project called bootmac in pmos which manages it for us
