ow to define an uncached linker region

Can anyone tell me how to define a region in the linker to be uncached? An example - I have a block ram I am using for SGDMA descriptor tables that I need to define as uncached... Thanks - Chris

I'm not sure... I think that if the next variable in the source code is also aligned, then the compiler will pad the bytes between the two, but this is just an assumption. You could run some tests to check that (and in that case, be sure to check at all optimization levels!)
