Microblaze design for FPGA

[nitinmrec]

The user application (coded in C) after compilation gives .elf file.
If the file size is greater that it can't fit in teh block RAMs. How to tell tha main code to jump to the executable sitting in FPGa or SDRAM through XPS or SDk

hello friend....
bootloader of microblaze...
you can use it to direct the uBlaze to fetch code from external memory
regards..

I did that...and then try to download the executable i.e. elf file in the flash memory which is attached as OPB peripheral. Whenever I try to program the flash memory the error comes saying MDM missing....any idea\??

 

[kvingle]

how are you programming the flash...?
have you refered to "Programming Flash Parts from XPS" section of edk help?

There are three ways to initialize external memory with software applications (ELF files) or data files:

Downloading a design using XMD

Using Bootloaders

Using System ACE™

please refer to edk help...for more details...Π

i think you need to check your opb_mdm version.

in ml401 board the opb_mdm needed to be changed to opb_mdm_v2_01_a.
