Arcadyan ARV7519PW

This device is distributed in the Netherlands by KPN as the `KPN Experia Box`

The PCB looks very similar to ARV752DPW22 when looking at the CPU, RAM, power supply and ethernet connectors. The ARV7519 has the same design origin but has only 1 USB connection and no ISDN capabilities.

→ Install OpenWrt (generic explanation)

As the bootloader is secured with an unknown password, the recommended way of installing OpenWRT at this time is by sending a custom u-boot image over UART in ASCII format. To make the device accept this, 3.3v should be supplied to the left side of R65, and the pads of R80 should be connected. When u-boot is sent to the device, it will run it from ram. In order to make it persist, a new u-boot image should be sent and then written to the device's flash at 0xB0000000. Afterwards, an OpenWRT image can be written to the device.

Please check out the article flash.layout. It contains an example and a couple of explanations.

→ port.serial.

Board voltage is 3.3V so you will need resistors if you want to connect it directly to PC serial port, or you can use usb to serial adapters which are already at 3.3v.

The bootstrap options is similar to the ARV752DPW. The PCB design underneath the SoC is almost identical. The bootstrap option described for the ARV752DPW work on the ARV7519 as well. The resistor numbers (R65 and R80) are equal as are the points of soldering.

This is the bootlog when booting with the reset button pressed. It also launches a webserver at 192.168.2.254. The webserver reports to be Apache 0.6.5, which seems false.
