New build for DIR-853 A3

Hi all,

Hope everyone is safe and doing well.

I am trying to build openwrt for a Dlink DIR-853 A3. It is a device given with my internet provider.
After having a look through the hardware online and in my own device I noticed that it is different from the DIR-853 A1 which uses a 16MB flash . Mine is a 128Mb NAND instead.

After using the work from Support for DIR-878 and which lucky for me only had 4 files changed from the main openwrt tree I managed to build an image that boots but I am getting some errors obviously.

I think most of the work to be done would be on the dts file I created.

Anyway this is the output of the kernel booting after flashing.

The image boots and Luci works. No changes are kept after reboot.
I can only see one wireless card (The 802.11AC) and the connection doesnt seem stable and thats just for SSH And Luci at the moment.

Thaks for looking.

K.

I just realised I did not includ the errors for JFFS.

This continues from the boot process from the serial int he first post

I am by no means an expert, but from what I understand OpenWrt uses UBI instead of JFFS2 for NAND flash. You can read here and further down for info on that.

There are probably other MT7621 devices with NAND around and supported in OpenWrt so taking a look at how they do it might maybe help?

Good luck on your endeavours :slightly_smiling_face:.

Thanks a lot I will have a read through.

I did see a reference about UBI on the Mir3G dts file so I will dig into that as well.

Cheers.

I see now you're the same guy that responded on the DIR-878 thread. Thanks for that!

You can also hop onto IRC and ask for pointers, might take a while until someone knowledgeable responds but it never hurts to try (#openwrt or #openwrt-devel on Freenode).

It has been a while since I used IRC but I will give it a go. Considering my limited knowledge in the area and the amount of details that I omitted/added wrong I am surprised that it even boots!

Just an update. I managed to make it work thanks to code from others. This is where the issue was in the mt7621.mk file and after too many combinations this is the one that worked .

define Device/dlink_dir-853-a3
	UBINIZE_OPTS := -E 5
	BLOCKSIZE := 128k
	PAGESIZE := 2048
	KERNEL_SIZE := 4096k
	DEVICE_VENDOR := D-Link
  DEVICE_MODEL := DIR-853
	DEVICE_VARIANT := A3
	KERNEL_INITRAMFS := $$(KERNEL) | ubootpad96
	IMAGES += factory.bin
	DEVICE_PACKAGES :=  kmod-mt7615e kmod-usb3 \
	kmod-usb-ledtrig-usbport wpad-basic uboot-envtools
	IMAGE/factory.bin := append-kernel | ubootpad96 | pad-to $$(KERNEL_SIZE) |\
	append-ubi
endef

I did use the UBI header. The specoal ubootpad96 had to be added before padding to kernel size to then add the ubi at the end.

I did a test with reboot which save the changes.

This is the bootlog now in case someone has a similar issue

That's quick (and great). Will you be submitting a patch?

Not at all. The issue was with my syntax. It took me a while to get around the syntax in the MK file.

This is to the "ubootpad96" extra padding for this board. The other device using it is not a NAND so it didn't have to use UBI.

Anyway R1 is probably same like A1 with 16mb flash :confused:

Do you happen to have pictures of the inside of the device? and the factory bootlog by any chance?

anyway how to open this case i unscrewed 4 screws and now?

Just a warning but the DIR-878-A1 & the DIR-878-A1-R1 are different
the boot loader & partition layout's are all different & not compatible with each other
the firmware is very different the Russian version is much better :slight_smile:
this maybe the same for the DIR-853-A3

Anyway, the R1 firmware can be easily installed on the Russian version and then return to the European version :slight_smile: info from ru support :slight_smile:
this commands from a1
https://gist.github.com/a2nt/10b96f421d18f501ed238a063601291e :stuck_out_tongue:
DIR853/EE=A1/R1
DIR853/ET=A3

I managed to remove the top cover with the help of a flat head screwdriver. I am not sure this is the correct method as I tend to always break a clip when I do that.

can you also post the output of "dmesg"? The flash is diffnately different as mine has 128mb and yours is only 16mb. I guess it's a similar chip to the A1/A2 model.

Having said that the board on the A3 has "DIR-1360 Ver 1.0" written on it. I compared pictures with the exo DIR-1360 and they look the same, I guess Dlink used that board for this specific model.

Nevertheless Lucky1's work on the ubootpad96+mtdsplit made it easy for someone like me to get a working openwrt image on the DIR-853-A3.

EDIT: Just to confirm that my device is A3 which is completely different from A1/R1.

Could you take a photo of the latches?
