Hello All,
I've acquired the DGL-5500 but saw it's still stuck on the legacy ar71xx target. If there's any way to get this re-ported over to ath79? I'd love to help, just need some guidance on how.
The first step is to open the case (and remove metal shield covers if there are any) and record the model of every chip on the board and start researching them.
You should have a UART serial cable, and look for the 4 pins (or 4 solder holes) on the board that are used for UART
Telling us the FCC ID will help because you can look up internal photos here, the rest of us (and you) can have a general idea of what the board looks like
Then look at DTS files for other boards with the same SOC chip so you can become familiar with how the kernel is configured in ath79
https://github.com/openwrt/openwrt/tree/master/target/linux/ath79/dts
Thanks for the guidance. Here's the information I found while digging:
D-Link Wireless AC1300 Gaming Router DGL-5500
FCC ID - KA2GL5500A1
Internal Photos FCC PDF
16 MB NAND, 128 MB RAM
2.4 ghz - QCA9558 (3T3R)
5.0 ghz - QCA9882 (2T2R)
RAM modules - Nanya NT5TU32M16DG-AC × 2
ETH - QCA9558
Switch - AR8327
Here's some pics when I took apart the DGL-5500. UART pins have been removed, per the image below. Below the heatsink is the 5 ghz module, where the module is exposed in pg 6 of the FCC PDF:
Bottom is the 2.4 ghz module, exposed on pg 5 of the FCC PDF:
Based on the above research, I found the TP-Link RE350K to be the most similar (the QCA9558 on RE350K is 2T2R), where its DTS is qca9558_tplink_re350k-v1.dts and references the qca955x.dtsi.
Will the UART be required to pull more definitive info to fill into the remaining fields for the DGL-5500? I have a UART, just not sure how to get header pins and where i'd solder it to. My guess is the 4 copper rings from the bottom.
Additionally, if I could get that info from a working instance of OpenWRT to make it easier, the device is already running 19.07.4.
I would say UART is required here, otherwise it will be a struggle. Here is a soldering guide with a similar situation. You just need a standard straight pin header and you pinch off 4 pins from the row. If you are not able to solder it is possible to bend small paperclips to make a pin with a friction fit.
So i'm just waiting for my soldering kit. Once I get the UART pins soldered in, what would I begin to do?
If you have a multimeter, measure voltage between each pin and something on the board you know is ground, in order to find the 3.3V and Ground pins.
Don't use the 3.3V pin at all, I like to bend it so I always know which one not to use.
That leaves Ground which is known, and TX and RX which is not known. Connect ground to ground, and you can guess the data lines, if you have them flipped then theres simply nothing in the console when you power the router.
When you have a console up and running, probably when you turn on the board it is u-boot as the bootloader
you should be able to interrupt the boot by pressing any key, print the uboot environment with the command firstboot, copy that somewhere, and then reset to reboot the board.
Let it fully boot and copy the entire bootlog / kernel log somewhere. If you need to print the kernel log again the command is dmesg
figure out which mtd device is the ART partition
cat /proc/mtd
dump the contents of ART and copy that somewhere (replace x with number)
hexdump -C /dev/mtdX
start taking a look at the DTS for similar products. This file represents the unique way that the kernel is configured for each device. In ath79 every device actually gets the same kernel, and the DTS is what tells the kernel what each device has.
Here is some similar DTS files
3 is a DTSI which is a common part of the DTS for multiple devices, they are split into a separate file to save space in the code and the relevant devices have an include line in their DTS for the DTSI.
So I have soldered the UART and was able to connect in putty to receive the bootlog, but for some reason I couldn't interrupt uboot.
UART Layout:
Baud rate - 115200
Ground - nearest to heatsink
RX
TX
3.3v
I'm going to try resoldering the third pin again to see if perhaps i just goofed on it. Any other ideas I could try to help bypass uboot? I've attempted to change serial settings, different usb ports, updated the USB to UART cable's drivers, rebooted, nada.

Look for small solder pads next to that third pin, try to verify if one of them is continuous with the pin. Then try to verify that the other side traces on the board to the SOC to make sure. If the SOC has pins exposed you can also do continuity/resistance test between that and the solder pad (with the board off).
Sometimes on a development board they have a very low resistor making the trace connection on the board, and then for the production version they simply don't put it on the board. Usually a resistor is not needed and you can just put solder to bridge them.
Unfortunately i'm not sure what I'm looking for..is the picture I sent of the front and back sufficient to hopefully help me look for what we're trying to find?
nevermind just try to verify which pins are 3V and GND, after you solder a pin header
Sorry I think I misunderstood the situation, also let me be more clear
theres 2 possibilities
-
the bootdelay is so small that you cannot be fast enough to interrupt boot. holding a key while powering the board may help
-
like I said, the RX line of the UART is not connected to the chip, there is a resistor that is either missing or needs to be removed or replaced with a short (some solder)
