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.

Hi all,

I'm trying to run u-boot on our MPC8266-PCI board. I'm using the latest CVS tree 0.4.5 from sourceforge. I found MPC8260ADS.h and MPC8266ADS.h in the configs directory. Trying the MPC8266ADS configuration and starting it ends with no console output at all. Trying the MPC8260ADS configuration with CONFIG_ADSTYPE=CFG_8266ADS ends with a bus fault after some console outputs (see below). What am I doing wrong?
