What happened to the D-Link DIR-510L?

Yes I have the device, and I want to try to get OpenWRT running. I've used it for several years with stock firmware, but it has become unreliable. I was thinking of factory reset, but then I remembered there was some effort on getting OpenWRT running which is much preferred since stock firmware is poor. However, I'm not able to dedicate time for a couple of weeks.

In the meantime, I need some education on how this process works. I've flashed routers with OpenWRT and DD-WRT before, but the process I've seen described is quite different. I need to understand what's going on better.

  1. Should I get an SPI programmer? What is the recommendation?
  2. what is the process for capturing the backup before starting?
  3. what is JBOOT? mtd partitions?
  4. Understanding combination of serial access with PUTTY as well as file transfer with TFTP?

@timg11

  1. You can make backup without SPI Programmer. But when router become brick, SPI programmer is the only chance to revert changes.
  2. There is two ways:
    a. desolder flash and make backup with SPI Programmer
    b. You need connect to serial console: (57200 8N1)

dd if=/dev/mtd0 of=/tmp/www3/dir-510l-whole-flash.bin

And download through the builtin httpd:
http://192.168.0.1/dir-510l-whole-flash.bin
3. JBOOT is closed D-link bootloader. Mtd layout You can find here:
https://openwrt.org/toh/d-link/d-link_dir-510l_a1
4. Serial console is nescessary. In this router TFTP isn't used.

Every vendor have his own system. This router was maked by Amit for D-Link. JBOOT bootloader causes that work with this devices is different. You can upload images by JBOOT recovery web interface.

I hope You didn't forgot about this topic!

Just found this thread after digging through my notepad, finding a sketch from the time just before the forum disappeared. I was on the old thread, but none of the later posts were recovered. However back then I had tried to find the circuit around the embedded MSP430 controller that handles the power and charging:

I remember there were some weird effects when switching the device on and booting OpenWRT - you just couldn't switch it back off without detaching the battery.
The slider switch "Router <-> OFF <-> charger" is connected to a MSP430 Microcontroller (Pins 9/10), just as the two LEDs (Pins 18/19) and the bq24195l battery charger (i2c, Pins 14,15).

MSP430 connects to MT7620 via UART (MSP430 Pins 3/4, apparently 4800 8N1), but I couldn't make sense out of the communication protocol yet.
The binary that handles communication to that chip in the stock firmware seemed to be mcuinfo_cdm56cdl, but I don't have the tools and skills required to reverse engineer that properly to find out how to talk to it (so we could at least shutdown the device, maybe even read the battery status):
https://onlinedisassembler.com/odaweb/kLPxxGw5

So, is anyone still on this? I have a device to test :slight_smile:

@s_2, I have the device but have not had a chance to get back to working on it. Maybe in the next month or so?
I've installed OpenWRT on more traditional routers, but this one seems substantially more complex, so I'm trying to learn enough so I don't brick it trying. I already learned about backing up via the serial console, JBOOT, etc. Now you are saying there is a companion MSP430 microcontroller that is doing some other functions for power and charging? Since I don't use the DIR-510L as a charger, or in self-powered mode, I'd be happy to disable that and remove the battery and only power it over USB. Do you have any schematic, photos, or other notes you can share?

If you just want the device to be powered 24/7 without battery, you could use the image I downloaded from a link in the old forum on May 3rd, cannot remember whether it was built by @CHKDSK88 or @lowmaster. However they did not brick my device :slight_smile:
http://sebastianschaper.net/openwrt/openwrt-ramips-mt7620-dlink_dir-510l-squashfs-factory.bin
http://sebastianschaper.net/openwrt/openwrt-ramips-mt7620-dlink_dir-510l-squashfs-sysupgrade.bin

I think the latest version even contained the GPIOs for enabling the USB Hub ports, I don't have specific notes about those though. The only scribble I found on paper was this about MSP430, wanted to make a nice and clean schematic with EAGLE, but then the forum was gone and I never continued :blush:

DIR510L_MSP430

I think I will have some time next month (one week of vacation after christmas). As far as I remember, I had destroyed the MSP430 UART connection on one device while testing, but I might find the issue with the new microscope soon :slight_smile:

By the way, there also seems to be somewhat acceptable support for MT7610E by now, which should probably be included when someone intends to build a new image:

I can go back to work with this router. Still I don't have a device, so I need help. :wink:

At this moment my images don't make device a brick.

For support 7610 I need whole flash or config partition dump.

@s_2
Do You know which mt7620 pins are connected to MSP430?

I think it should be /dev/ttyS0 according to the strings in the binary that controls the chip in the stock firmware, not sure whether it's the same UART that would also enumerate as ttyS0 in openwrt.
It's difficult to follow the traces within the multi-layer pcb, I have no clue yet as to where exactly they are physically connecting to MT7620.

Upon attaching the battery, MSP apparently sends some version info at 600 Baud, then switches to 4800. But I broke the UART connection on my device back then (probably cut some trace with oscilloscope probes), so even after flashing back to stock it will show battery charge always at 0% (curiously it can still be switched off using the slider).

I will have to find my board within the piles of electronics boxes and have a look at the bootlog again for the mtd layout / position of the wifi calibration data (or am I just confusing this with the ART partition of ar71xx? what exactly do you need from the full flash, just the layout or some binary blob that is the same for all DIR510 ?)

I disabled uartf. In next image I will turn it on.

I need only config partition dump. 7610 have calibration data stored in this partition. Flash layout is described at openwrt wiki.


New images. Should support 5GHz wifi. Ethernet is LAN. Second uart is enabled. I recommend use it with serial console.

Could someone give a bootlog and info what work?

Found the device :slight_smile:
Here's my mtd7: http://sebastianschaper.net/openwrt/dir510l_mtd7.bin

There was also a link (actually still working) in the old archived thread from a post by lowmaster, where he uploaded his mtd0 (full flash), that also included mtd7.
Comparing the two there's many differences, so I wonder which part will be MT7610 EEPROM...

0xE000 is apparently for MT7620 ethernet, according to the .dts in your github :slight_smile:

Looking at the DIR-810L pull request for MT76x0, I guess we will be needing something like this?! (with the correct offset and adding package kmod-mt76x0e)

&pcie0 {
	mt76@0,0 {
		reg = <0x0000 0 0 0 0>;
		mediatek,mtd-eeprom = <&config 0x????>;
		ieee80211-freq-limit = <5000000 6000000>;
	};
};

Here You can find my changes.

okay apparently I was too slow with dumping the mtd partition :smile:

MT7610 looks good actually, iw wlan0 scan works perfectly and will list 5GHz networks :slight_smile:

Serial bootlog until console is disabled:

So I guess the only remaining issue now would be telling MSP430 to shutdown the device without detaching battery. I will check whether I can fix my UART traces and try to capture the transmission again :slight_smile:

I forgot about lowmaster dump. :slight_smile:

I need some info:

  1. ifconfig -a (For wifi 5GHz MAC. At this moment is not implemented. My PR for mt76 driver is pending.)
  2. How many serials You see in system?
  3. Is status LED working?
  4. Are USB working?
  5. What (except MSP) isn't working?

Curiously, when I try to scan 5GHz with LuCI it will not finish scanning, also the radio0 shows "Wireless not associated".
If I try to disable and enable via LuCI, I will only have 2.4 GHz (showing as wlan0), so it's probably just an issue with ifconfig for 5GHz.

After rebooting, both interfaces are back:

// edit: after rebooting both of them even work in LuCI, status is shown and Channels can be scanned :slight_smile: apparently needed one more restart after flashing (or I shouldn't have ifconfig wlan0 up outside of LuCI!?)

There's two serials, however no more console after booting.

root@OpenWrt:~# ls /dev/tty*
/dev/tty    /dev/ttyS0  /dev/ttyS1
root@OpenWrt:~#

Status LED works, flashing while booting, steady when done. (except for LED2 which is controlled by MSP)

USB is working too:slight_smile:

Support for 7610 is a new thing. It could have bugs. Please try turn on 7610 in AP mode and connect to router.

Things to do:

  1. Repair console
  2. Prepare for wlan 0 MAC setting
  3. Check communication with MSP

Please let me know if You repair uart.

There is not many things to do. Maybe it will be supported before 19.01. :slight_smile:

It is connecting and I can use it for any traffic (LuCI, Web) when it's configured in AP mode.

However it seems to be connecting at only 54 MBit; when iperf3 server is running on OpenWRT, I can get about 20 MBit/s, when the server is on the PC instead it will vary a lot around 13 MBit/s.

I tried switching to 2.4 GHz then for comparison, but did not work (do I have to enable WPA2 PSK first? only did this for 5 GHz), had to restart after changing configuration etc.
So it's probably the driver not yet running smoothly, but great to have some support at all :slight_smile:

Soldered some wires to the UART pins, hope I'll find time for more testing next week, maybe even at the weekend :slight_smile:

This is because firmware loading, IMHO.

On the very first boot the system formats /overlay and the user helper script which loads the wifi's firmware is delayed until the storage gets ready to store the blob extracted from the flash.

if you run again in such issue, it can happen when luci or driver is slow and there is many channels, an easy solution is to increase Maximum wait time for network activity in uhttpd settings

I not recommend use luci at this moment. Can You turn off wlan1 and set only wlan0 to ac mode?
