Hi. I have a D-Link DAP-1720 and I'd like to know if there's any compatible Openwrt firmware that could be installed.
I also would appreciate any help to guide me to build it.
Provide info about the hardware (SoC and radio chipset) , and we'll tell you if the device could be supported down the road, currently it's not...
Hi @frollic Thanks for your prompt reply.
Here are the information I have about it:
System-On-Chip (SoC) / CPU: QCA9563-AL3A
Eth Phy: Atheros AR8033-AL1A
RAM chip: W9751G6KB25J DDR DRAM, 32MX16, 0.4ns, CMOS, PBGA84
Wireless 1 (2.4 GHz): QCA9563-AL3A
Wireless 2 (5 GHz): QCA9880-BR4A
This is the link for FCC ID site: https://fccid.io/KA2AP1720A1/Internal-Photos/Internal-Photos-3243131
Here's a couple of similar devices https://openwrt.org/toh/views/toh_extended_all?dataflt[CPU*~]=QCA9563&dataflt[WLAN+Hardware*~]=QCA9880
Check if any of them installs through initramfs, if that's the case, try booting it on your device,
if not, you'll need to create your own initramfs based on any of those.
You'll probably need serial console access for the 2nd option, but that's something you'd need down the road anyway.
I've spent the last week adding the device to Openwrt. I am having a little problem with 5 GHz support and have decided it it time to ask for help. For anyone with the device I found the serial connection requires 5 volts from my FTDi to properly send information to the device. The device's RX is through gpio 18. I'm guessing that is the reason for needing 5 vs the normal 3.3 volts.
My notes from adding the device are:
Added information to images/generic.mk
SOC := qca9563
SEAMA_SIGNATURE := wapac28_dlink.2015_dap1720
IMAGE_SIZE := 15872k
Fixed uboot checksum using entry in:
09_fix-checksum
Used "Ubiquiti UniFi AC Lite" dts files as a base.
Configured led gpios
first signal indicator leds as power green, power red -> 19, 20
second and third signal indicator leds as wlan2g, wlan5g -> 15, 16
wps led as wps_red -> 5
Configured button gpios
reset as reset -> 1
wps as wps -> 2
Configured flash partitions
Configured eth0 to use phy0
Fixed ethernet mac address using entry in:
10_fix_eth_mac.sh
Pull caldata using dts and fix 2.4g wifi mac address using entry in:
10_fix_wifi_mac
Pull caldata and add mac address for 5g wifi using entry in:
11-ath10k-caldata
Added lan using entry in:
02_network
My problem is the 5 GHz starts and I can connect to it but it isn't stable. If I ping from the device to a connected client the pings work for 5 or 6 seconds then it goes "down" for 14 to 15 seconds and then it repeats. Any help on how to trace this problem is appreciated.

Good work!
I'm interested in the device too (planning to purchase, no hardware here yet).
Did you have a look at the GPL source?
P.S.
In similar devices (DAP-1620, DAP-X1860) the RSSI leds are used for RSSI.
I did. Before I got the serial working I compiled the GPL and added Dropbear to get ssh access. The ATH drivers in the GPL are pre-compiled, and I really don't have the expertise to delve into them. It is so frustratingly close to working. I noticed some abnormalities with the gpios not sure how they fit in. For example gpio 3 when direction is set to out reading the gpio has some type of data on it.
Did you try kmod-ath10k-ct instead of the smallbuffers one?
EDIT: see also
EDIT2: definitely you should try kmod-ath10k and ath10k-firmware-qca988x instead of the -ct versions.
Where is the green wps led? could it be 4 or 6?
EDIT: definitely 6, it's in prebuild/usr/sbin/gpiod.
Or maybe 3?
Another find from gpiod: along with the reset button and the WPS button handler, there's a third handler called mode_switch_handler executed every second.
It checks the value of GPIO 8, and may execute either /etc/scripts/setswitch.sh EXTENDER or /etc/scripts/setswitch.sh ROUTER.
Is there a slide switch or some other extra button on the device?
EDIT:
I procured a device and would like to join the porting efforts.
How did you figure what offset in the art partition the ath10k calibration data should be read from?
Also, UART seems like 3.3v (definitely on the Tx side); what made you go for 5v?
(1.25mm pitch is annoying though)
P.S.
The PCB does have some unpopulated footprints (e.g., D1 led, SW3 slide switch) so there should be some more relevant GPIOs available for hardware mods. Maybe one of them is GPIO3 or GPIO8.
Interesting, I have some 3.3v motion switches, etc that might be fun to add.
I've updated my github. The rssileds are now supported. Works great so far. The connection issue seems to be a problem with my desktop wifi. I haven't looked further because it connects to my mesh without issue. I added some of your changes into the DTS thanks!
I'm glad you had me look at this again. I can now take it off my to do list

Glad it works better for you!
If you find which GPIO is which, do tell. I couldn't even get the missing D1 LED to work, but maybe I was too tired and made stupid mistakes. The only GPIO that seems to do something annoying is GPIO11, which probably has something to do with Ethernet.
It's been a while.
