16:52 <tortoise> trying to get wifi working with this radxa-zero, so I populated /lib/firmware/brcm with the contents from https://github.com/LibreELEC/brcmfmac_sdio-firmware

16:52 <tortoise> doesn't work though, boot takes a bit longer and then when it does boot dmesg shows faults with tracebacks into the brcm driver I think with a NULL ptr dereference. Guessing I missing something but this is all a little mysterious to me. Any tips?

16:54 <tortoise> I booted libreelec nightly build and wifi works fine there

16:55 <narmstrong> tortoise: perhaps the sdio irq breaks support for wlan

16:55 <narmstrong> tortoise: this was posted today https://lore.kernel.org/all/20221114093857.491695-1-peter.suti@streamunlimited.com/

16:58 <tortoise> hrmm, sounds like that was introduced more recently. I'm running the 5.15 kernel built by meta-meson. It wouldn't have the commit adding SDIO interrupt support right?

16:59 <narmstrong> I don't think, but perhaps it was backported, let me check

17:00 <narmstrong> yeah no

17:01 <narmstrong> and no other change has been added in more recent kernels

17:01 <narmstrong> perhaps a fix is missing in brcmfmac

20:15 <tortoise> I noticed that meta-meson already brings in some broadcom firmware by these dependencies

20:15 <tortoise> which I think refers to

20:15 <tortoise> https://github.com/superna9999/meta-meson/blob/kirkstone/conf/machine/include/amlogic-meson.inc#L18-L26

20:15 <tortoise> https://github.com/yoctoproject/poky/tree/master/meta/recipes-kernel/linux-firmware

20:15 <tortoise> which has pieces such as

20:15 <tortoise> https://github.com/yoctoproject/poky/blob/master/meta/recipes-kernel/linux-firmware/linux-firmware_20221012.bb#L260

20:15 <tortoise> but there is no bcm43456 in that linux-firmware package

20:15 <tortoise> So I'm going to try and exclude those parts of linux-firmware for now and try and bring in files in armbian (or other distributions) and see if I can get it to work

20:15 <tortoise> https://github.com/armbian/firmware/tree/master/brcm

20:17 <tortoise> Sort of a shot in the dark, but I previously was unaware that my libreelec files were potentially conflicting with the poky linux-firmware files

20:51 <tortoise> yeah the armbian files work, and I was wrong there do appear to be other boards using bcm43456 in that linux-firmware package, such as pine64 and rockpi4

21:20 <narmstrong> tortoise: yep the firmware situation is bad, I started using the ones from librelelec https://github.com/superna9999/meta-meson/blob/kirkstone/recipes-kernel/linux-firmware/linux-firmware_%25.bbappend but I should use the ones from armbian instead
