Honored Contributorquestion about sdram on nios II
After I finished my project and built it ,there is no any error or warning.But when I run my C project,it said :
"Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00 Processor is already paused Reading System ID at address 0x00000010: verified Initializing CPU cache (if present) OK Downloading 02000000 ( 0%) Downloaded 8KB in 0.2s (40.0KB/s) Verifying 02000000 ( 0%) Verify failed between address 0x2000000 and 0x2001EEB Leaving target processor paused." I use sdram as my only storage.Is it my project so large?I hope somebody help me to solve this problem.Thanks!!24 Replies
Altera_ForumIn that case you can start with the standard design, which already has the SDRAM controller, and add an on chip memory.

i want to use both bram(blockram) and external memory (sdram controller(ddr2/sdram))through niosii and i need to store more datas (image pixels) into sdram.

I don't know 'bram' but from a quick Google search it seems that it is Xilinx' name for internal dual-port sram. Now I'm ronfused. Do you want to use internal memory or externl sdram?
What do you mean by "usual steps" and "error occured"? - Altera_Forum
i instantiate bram in my simple module and access it through nios ii processor,i follow usual steps , error occured,anyone knows please help me
thank you - Altera_Forum
Have a look at the design examples for your kit. The standard nios example already has a Nios II CPU and a SDRAM controller configured for the chip on the board.

I have some of the pixels of image.and i want to store that datas into sdram .and retrive that datas through sdram for further process.is it possible please help me.

Well as I said there are several controllers available, but it depends on which memory chips you use. As an example you can have a look at that document (http://www.altera.com/literature/an/an398.pdf) for memories with a DDR interface.

What SDRAM chip do you have? --- Quote End --- I know to access nios ii with on chip memory.now instead of onchip mem i need to access dynamic ram and static ram with processor could you please tell me any documentation is available

i need to access nios ii processor ,what are the components are required to create processor and i want to use sdram and blockram please tell me the flow or any documentation is available please tell me
thank you
