Hello everyone! I am designing a PCB and I need to know if there is a possibility to swap SPI0_CLK and SPI0_CS by changing this line from: pins = "PC0", "PC1", "PC2", "PC3"; to pins = "PC0", "PC1", "PC3", "PC2"; Currently I don't have a board to check it myself. Any ideas if this would even work? Thanks!

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. Ref: https://elrepo.org/bugs/view.php?id=671 https://bugzilla.kernel.org/show_bug.cgi?id=103201 https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1398458 @Werner could you remove this limitation from my account? I couldn't even reply to my own topic yesterday.

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 [ 40.620798] brcmfmac mmc2:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.friendlyarm,nanopi-neo-air.txt failed with error -2 [ 40.620821] brcmfmac mmc2:0001:1: Falling back to sysfs fallback for: brcm/brcmfmac43430-sdio.friendlyarm,nanopi-neo-air.txt [ 101.475933] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430-sdio for chip BCM43430/1 [ 162.808829] brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-11), device may have limited channels available [ 162.813236] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM43430/1 wl0: Mar 30 2016 11:30:56 version 7.45.77.h8.4 FWID 01-ee8a6268 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 [ 10.549789] brcmfmac mmc2:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.friendlyarm,nanopi-neo-air.txt failed with error -2 [ 10.549807] brcmfmac mmc2:0001:1: Falling back to sysfs fallback for: brcm/brcmfmac43430-sdio.friendlyarm,nanopi-neo-air.txt [ 11.103778] brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430-sdio for chip BCM43430/1 [ 11.106615] brcmfmac: brcmf_c_process_clm_blob: no clm_blob available (err=-11), device may have limited channels available [ 11.107934] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM43430/1 wl0: Mar 30 2016 11:30:56 version 7.45.77.h8.4 FWID 01-ee8a6268 Here is the list of modules that I'm currently using (from /lib/modules/5.8.16-sunxi): Module Size Used by brcmfmac 180224 0 brcmutil 16384 1 brcmfmac cfg80211 471040 1 brcmfmac rfkill 20480 1 cfg80211 usb_f_acm 20480 1 u_serial 24576 1 usb_f_acm g_serial 16384 0 libcomposite 45056 2 g_serial,usb_f_acm pwrseq_simple 16384 1 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
