SRAM problem MPC5775K

I have a question about SRAM. I attached a part of the SRAM when viewed with Lauterbach. Some addresses can't be read. When I want to write to one address with parameter long, there is an bus error, but when i write with Lauterbach a quad value, the writing works and I can see the data afterwards. Do you know why there are bus errors at all and why the writing works with parameter quad?

So for example this command works:    Data.Set EA:0x40000000 %Quad 0

but this one is not working:                     Data.Set EA:0x40000000 %Long 0

I want to use the SSD Driver, so i must be able to write to RAM.


Thanks in advance
