Initialize the BRAMS with SDK (EDK 14.7)

Hello! I'm trying to simulate Microblaze processor with Modelsim for my final project.
I have already make the processor in XPS and compile the libraries but I don't find the option to initialize the BRAMS in SDK. ( I'm using EDK 14.7 )

Does anyone know how to initialize the BRAMS in this version of SDK ?

Thanks :)
(I know there is some other posts but is not working with this version)

What do you mean by initialize the BRAMs in the SDK? The SDK will generate the BRAM initialization files from your software code, AFAIK. Don't remember if there is a separate tool to do it, but a file can be generated that the testbench uses to load the BRAM, so that modelsim will run using the actual code.

Have you gone through Xilinx's documentation, as I recall they have a pretty decent user guide for implementing and simulating Microblaze systems.
I have gone through some documentation, but some of it is out of date.(Thats the reason I thought my problem was the BRAMS).

I have already run the testbench in Modelsim but I cannot see the output of the program i put into my microblaze using SDK. ( I have try to change the values of the LED that are connected by Gpio )

I really don't know if the testbench that XPS is generating is working properly or I should add some code into it.

It is enough to program in SDK and then to generate VHDL files in XPS?

Thank you :)
