Thanks for the detailed reply - please see my comments below

Well certainly that looks reasonable - I see from this line
> PARAMETER C_CLK_FREQ = 50_000_000
that you are using a 50MHz clock - in the kernel config there is a
parameter to set the system clock speed, and it defaults to 66MHz. You
don't mention if you have changed this, but it is necessary.
It's under kernel settings -> processor options -> clock frequency

That should all be ok - the port was originally done in 1MB of SRAM, so
your setup should be fine.

It's something that needs to be addressed - ideally you could just copy
xparameters.h into the kernel and be done with it, but it doesn't quite
work that way yet... :-(

OK, that's a good sign.

these look reasonable - check the clock frequency thing and let us know...
