Re: 2014.01 U-Boot for FDT and Non-FDT Kernel - GoFlex Net/GoFlex Home/Pogo E02/Dockstar/iConnect/Stora

Hi bodhi,

thanks for the new uBoot version.

Unfortunately i bricked one of my dockstart by simply flashing it from the old uBoot.
So I tried on my second, this time launching it from inside us boot

The same happens with the 2013.10

I'm sure I'm doing something wrong, but can not figure out what.

When I use JTAG to load the image into the bricked Dockstar I only get this (this log was captured from the working Dockstar, but they behave the same):

All help appreciated.
