How much ram to allocate for Exception memory?

I'm wondering how big of on-chip memory is recommended if pointing the exception vector to it in qsys/bsp? Is it always a fixed size (like an interrupt vector table), or does it grow dynamicall...

Unless you are very tight on memory, it's best not to mess with that. Even then don't try to change things down there unless you really understand what is going on. At best you are spending time for a very small return in memory. At worst you are introducing bugs that are very hard to find.

There is no reason to set the size of the text section. Its size is set automatically by the linker based on the size of your code. Note that QSYS has nothing to do with the text section. That is purely a software concept created by the linker. All QSYS needs to know is where the reset and exception addresses are.
