No CFI Table found in the address...

http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif Hi friends,

I am very new to Quartus and nios. I am using version 6.0 for both..

I have build a simple system using following components in SOPC builder,

Nios CPU

SSRAM

FLASH MEMORY

SSRAM BUS

LED Output

Switches

I have added system id also..

While programming my flash memory I will get an error saying NO CFI TABLE FOUND AT THE ADDRESS<base address of flash memory>.

I refered Flash Programmer User Guide and tried all the possible things and still facing the same problem..

Please help me out to resolve this problem..

With Regards

    Which board are you working on? a custom board or one of the demo boards?

    If it is your custom board, you should check if the Flash bus is connected correctly, than check the access cycles (timing), try to perform a read manufacturer ID or something similar.

    If you have a demo board and you only changed the FPGA configuration, compare its behaviour with the original configuration. If there is already some code in the flash try to read it with the debugger in the Nios IDE, and compare it with what you read with the original firmware. The address bus might be shifted for a bit or ...
