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.
