First off.
The MPC8260ADS config files will not run on a MPC8266ADS.
Most likely culprit here (Remember seeing the same thing when dd ther
initial port) is that it hangs when trying to initialise the =
(nonexisting)
4MB og SDRAM on the local bus that the MPC8260 has, and the MPC8266 =
doesn't.
The reason the config file for the MPC8266ADS don't give any output is =
most
likely because it loads at adifferent initial configuration address. =
(See
top of include/configs/MPC8266ADS.h for details)
To get it to work the way it is; Write the whole image to the start of =
the
FLASH (on a board with JP3 in 2-3 position this is 0xFF800000). Then =
set JP3
in the 1-2 position. The flash start and boot at 0xFE000000.
