Comfast CF-EW72 specs:
QCA9531+QCA9886
Hello,
Seems the (already supported) CF-E375AC is based on the QCA9886 too, but has the additional switch chip QCA9337. Can I try to flash that build anyway without bricking? Sorry for asking if that question seems too banal. Thanks for any help.

"Build", no - "develop", maybe (depends on the amount of effort the vendor spent on firmware verification/ authentification and signatures) --> look through the git history for previous commits adding support for new ath79 devices for a general idea.

Thanks. I got the EW72 hardware now and well ... I am trying it do it myself.
The comfast firmwares are based on an older Openwrt (I think 14.07), and I managed to circumvent the unknown root password and got full shell access. So no big problem to get out the GPIOs (/sys/kernel/debug/gpio) and to extract the ART partition to get the MAC locations.
So my first code (ath79) attempt looks like this (based on the code for another existing Comfast ath79 config) :

Using UART, running it gets it stuck at (boot loop)

Any help would be appreciated, I have never done this before. Thanks.
I think your last nvram partition is too large. Try making it smaller.

Are you sure that the nvram size is too big? I copied the setting from the binwalked Comfast adaptation of openwrt 14.07, it is "read only" and contains a 1:1 copy of the art partition. Should I rename it to art-backup? Thank you.
Comfast's 14.07:
mtdparts=spi0.0:64k(u-boot)ro,64k(art)ro,1536k(kernel),14592k(rootfs),64k(configs),64k(nvram)ro,16128k@0x20000(firmware) rootfstype=squashfs,jffs2 noinitrd
Mine (tested with 18.06 and master):
mtdparts=spi0.0:64k(u-boot)ro,64k(art)ro,16192k(firmware),64k(nvram)ro console=ttyS0,115200 rootfstype=squashfs noinitrd
Since it crashes during what seems to be the network hardware setup discovery ... the qca9531 has a 5port switch included, but only 2 port are used in the EW72. Comfast config lines in 02_network from 14.07 are:
cf-ew72)
ucidef_set_interfaces_lan_wan "eth0" "eth1"
ucidef_add_switch "switch0" "1" "1"
ucidef_add_switch_vlan "switch0" "1" "0 1 2 3 4"
I tried different adaptations with ath79/dts and ar71xx/mach versions, but no luck so far.

A very big thank you, biangbiangmian. That made the thing.
Also thanks to Comfasts Ding Tengfei for publishing this. That saves me lots of trials ++++++++

I made a ath79/dts version for the CF-EW72. My version solves also the bogus MAC problem I had with the above ar71xx version. The MAC for the ath10k wlan did show as 12:34:45:78:90:12. My version patches the bogus MAC in firmware.bin to the MAC extracted from the caldata/art partition.
Since the CF-EW72 has 8 leds, but only 4 ore used by the official fw, I added a LED for the second WLAN. The 3 remaining GPIO leds can be configured ( rssileds ... ).
