In my board specific code, after initialization of the SDRAM, I have
code that writes the address as data to that address - write 0x0 to 0x0,
0x4 to 0x4, etc. After the Software Emulation Exception, I go into the SDRAM and the code is copied correctly in the used areas, and my pattern is in the other areas.
And which data are you RADING from SDRAM?
Because of this, I don't think my SDRAM settings are being changed.
You wrote you are using a BDI2000 - you can use it to single step into the code in SDRAM. What does this give? And if you get an exception - where does it happen? What was the incorrect data?
You got the tools - use it to analyze your problem [or just save the time and re-check your SDRAM initialization against the chip manufacturer's manual; at least this is what I would do if I was in your position.]
