> <@hexagonwin:matrix.org> Hi! I'm trying to port OpenWrt to a new device named `ipTIME A3004NS-dual`.
> It is from a manufacturer called `EFM Networks` and a device with almost the same spec and manufacturer is supported in OpenWrt currently, and that is `ipTIME A8004T`.

> The device's spec is like the following.

> Ralink MT7621A 880mhz
> DDR3 256mb ram
> one usb 3 port
> four giga lan port
> one wan port
> *UART, JTAG IN THE BOARD*

> I just copied a8004t patch, removed many nodes and then edited partition part to fit my device, information from stock firm boot log.
> Then I installed resulting initramfs using tftp, and the error log I posted above happened. I can also install the initramfs using stock firm's web gui, and same issue happen in boot. (The method of installing owrt in a8004t is to install `initramfs` with stock web gui and doing `sysupgrade` with `sysupgrade` image)

(Just my addition again)
I think I did something wrong in the partition information in dts, can someone please check if I wrote something wrong in it? I thought that I would have to right it exactly as the stock firm boot log said, but in the stock boot log it shows like this
```
   Load Address: 80001000
   Entry Point:  8000f500
```
but in owrt it is like this...
```
   Load Address: 80001000
   Entry Point:  80001000
```
What in the dts changes these??
