Dear Armbian community,

 

First of all, I am aware of the fact that what I am trying to achieve is not supported, but let me ask anyway. What I am trying to do is to build my custom root filesystem for my specific embedded needs (which is pretty minimal and without systemd) while still using kernel (5.8.16-sunxi) and modules provided by Armbian. It is going great so far, but the first issue I need to figure out is why there are approximately 60 second delays between each brcmf_fw_alloc_request calls (full dmesg available here):

 

[ 40.602927] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430-sdio for chip BCM43430/1

On image provided by Armbian brcmfmac dmesg is exactly the same, but there are no such a long delays between brcmf_fw_alloc_request calls (full dmesg available here):

 

[   10.540426] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430-sdio for chip BCM43430/1

Here is the list of modules that I'm currently using (from /lib/modules/5.8.16-sunxi):

sunxi                  20480  0
phy_generic            20480  2 sunxi

 

Does anybody know a way to remove these delays without involving systemd at all? Maybe udev would be sufficient? Any opinions are appreciated

It seems like the problem is caused by `CONFIG_FW_LOADER_USER_HELPER_FALLBACK` kernel option. Anyway, I have to compile my own kernel. In the kernel provided by Armbian this option is turned on.

@Werner could you remove this limitation from my account? I couldn't even reply to my own topic yesterday.

The restriction usually lifts automatically as soon as you receive a like from somebody or just wait after a few days.

Though I removed it for you.
