I have a custom ppc405ep board with 128MB SDRAM, very similar to the AMCC Taihu board. U-Boot 1.1.4 works perfectly fine. But version 1.3.4 freezes after saying "Relocating now" in debug mode.
This is an indication of an SDRAM initialization problem.
You were right...
Even 1.3.4 is old. I suggest that you give the latest git version a try. And please use the code in cpu/ppc4xx/sdram.c to init the SDRAM controller. How
Actually that was exactly the problem: I had overloaded the function "initdram(int board)" in my "board.c" to initialize the SDRAM stuff. The solution was to trash my own code and let U-Boot use the routines defined in cpu/ppc4xx/sdram.c. Now it works perfectly.
Thank you very much for your help!
