RE: [microblaze-uclinux] A simple bootloader?

Hello Ryan,
You can search these archives and the Xilinx embedded processors forums.


In short, the gist is that you need to verify that you can access the
memory in the first place with either a simple program that writes to
memory then checks it to see that it's correct; or you can check it with
XMD and peek and poke the memory space.  If that is working then you
have to set the start address for your executable to the location of the
external memory. Make the system set to xmdstub mode and initialize the
bram with the xmdstub. Download the bitfile, then use either xmd to dow
the elf file or gdb to load the file (not sure how to do the last one).


This is another nice FAQ question that I've not seen posted.  There is a
lot of discussion about it in the Xilinx forums though.

Good luck,
/ks

|I'm new to FPGA design so I'm sorry for the remedial question 
|-- but I am having one hell of a time programing a Spartan3 
|Start Board.  I can run programs out of BRAM, but running 
|stuff out of SRAM is a different story.
|
|I'm not asking for detailed instructions, but are there any 
|nice websites or documents aside from the Xilinx app notes 
|that describe how to do this stuff?
