Hi,
my cubietruck works for few days flawless with 4.19.y,
but after 5 days i need to power off for a while and when i restart i lost my wifi hardware :-(
brcmfmac: brcmf_attach: dongle is not responding: err=-110
even power off for a long time didn't help, i've tried reboot / power off several times, but wifi remains brocken with the above message
Googling this i found Hans de Goede 's work 0001-ARM-dts-sun7i-Disable-OOB-IRQ-for-brcm-wifi-on-Cubie.patch
here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=908438
and here:
https://patchwork.kernel.org/patch/10621433/#22252025
"With an unmodified 4.17 kernel both boards intermittently would come up
with non working wifi with the following errors:
brcmfmac: brcmf_sdio_bus_rxctl: resumed on timeout
brcmfmac: brcmf_bus_started: failed: -110
brcmfmac: brcmf_attach: dongle is not responding: err=-110
brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed"
copy 0001-ARM-dts-sun7i-Disable-OOB-IRQ-for-brcm-wifi-on-Cubie.patch in build/userpatches/kernel/sunxi-dev
the patch applies OK:
&mmc3 {
pinctrl-names = "default";
pinctrl-0 = <&mmc3_pins_a>;
vmmc-supply = <®_vcc3v3>;
mmc-pwrseq = <&mmc3_pwrseq>;
bus-width = <4>;
non-removable;
status = "okay";
brcmf: wifi@1 {
reg = <1>;
compatible = "brcm,bcm4329-fmac";
/*

};
};
&mmc3_pins_a {
/* AP6210 requires pull-up */
bias-pull-up;
};
but now kernel 4.19.y (Armbian) fails to compile with syntax error:
Error: arch/arm/boot/dts/sun7i-a20-cubietruck.dts:238.6-7 syntax error
here i have a lack of knowlege so do not see any reason for that syntax error :-(
as it worked before for me there must be some other difference, so
when booting stock android from nand (pulling out my arbian sd card) and restart without power off from plugged in sdcard

and i got my wifi back :-)
--- i've tried to reproduce this, but power off for 15min does not show up this error
edit: after having my cubietruck offline for some hours (6 or so) after power on wifi was gone again:
brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43362-sdio for chip BCM43362/1

brcmfmac: brcmf_sdio_firmware_callback: brcmf_attach failed
reboot does not help,
but after booting android from nand an shutting anndroid down (not just resetting)
i've my wifi back:

so same bit or a blob remains on the chipset making it work stable wifi on cubietruck with mainline kernel 4.19 - even if it is just a workaround.....
an other point is that nand starts partialy working with mainline kernel 4.19:
[ 2.191160] nand: device found, Manufacturer ID: 0xad, Chip ID: 0xde

[ 2.196946] 0x000000000000-0x000000400000 : "SPL"
but then is too much marked as bad block ..... but it might be possible to put newer u-boot on nand to get rid of the sdcard
