Do you have any debug facilities? Maybe a BDI2000? It could be a board
fault or something wrong with text base, etc.

This is my first time working with uboot, so naturally I am having some issues. My issue is that I can't get any response from the board after we flash it with the binary image. I don't know if I am flashing it in the wrong location, or if it is because the configurations in the header files that I changed are wrong. I have tried flashing it in various locations such as start of memory, CONFIG_SYS_TEXT_BASE location (changed to our needs of 0xFF8000000), etc. I also have changed a lot of the memory configurations from the MPC8349EMDS such as the timing configs, ddrlawbar and ddrlawar, sdram configs and modes, etc.
