-If you bricked your uboot you can load a functional one via uart. For that you need to bridge r64 (top) and r80 (bottom) with some solder. After that the soc boots up in UART mode and you can transfer your [[http://downloads.openwrt.org/attitude_adjustment/12.09-rc1/lantiq/danube/uboot-lantiq-arv4520PW_ramboot/u-boot.asc|u-boot.asc]] through a serial connection:+ 
 +If you bricked your uboot you can load a functional one via uart. For that you need to bridge r64 (top) and r80 (bottom) with some solder. After that the soc boots up in UART mode. You can verfy that you are in UART-Mode if after powering up the device it writes the follwoing on the serial: 
 +   
 +  ROM VER: 1.0.3 
 +  CFG 04 
 +  Read EEPROMX 
 +  X 
 +  UART

 +Now you can transfer your [[http://downloads.openwrt.org/attitude_adjustment/12.09-rc1/lantiq/danube/uboot-lantiq-arv4520PW_ramboot/u-boot.asc|u-boot.asc]] through a serial connection:
  cat u-boot.asc > /dev/ttyUSB0   cat u-boot.asc > /dev/ttyUSB0
 +There exist quite a few more Modes, that are accesible through briding empty pads as shown in this [[ http://thread.gmane.org/gmane.comp.embedded.openwrt.devel/17762|thread]]. But none other than default and UART-Mode seems to be usefull.
