Re: [microblaze-uclinux] auto-config.in error

[begg0016@xxxxxxxxxxxxxxx]

Quoting begg0016@xxxxxxxxxxxxxxx:

From some extra reading, i have found that there is a weakness in uclinux as it
does not support the newer versions of DDR and SDRAM controllers as they uses
multiple banks. 

I am using 7.1. Is there any method to get around this problem. I have tried
changing the tcl and mld file however i still have the eram start error.

Is there a solution?

thanks again,

Lyndon.

Its major weakness is probably that it doesn't support the newer version 
of the DDR (and maybe SDRAM) controllers - you'll note the uclinux-auto 
platform uses the deprecated version of the DDR controller.  This is 
because the newer version of the core uses multipel banks, and stuff 
like that, which the MLD/Tcl doesn't support yet.  It should be pretty 
simple to add, I'm just waiting on some doco from Xilinx to help me make 
the modifications.
