HELP !

Hi all . "

board : Altera Stratix ii EP2S180

FLASH :AM29LV128MH103REI

PROBLEM: 1 (When running )

Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Pausing target processor: OK

Reading System ID at address 0x02030828: verified

Initializing CPU cache (if present)

OK

Leaving target processor paused

2 (When programming flash with flash-program shell)

Using cable "USB-Blaster [USB-0]", device 1, instance 0x00

Resetting and pausing target processor: OK

Reading System ID at address 0x02030828: No CFI table found at address 0x00000000

Leaving target processor paused

i see lots of people met those 2 problems,and i see the suggestions some good people say .but it still do not work fine .

At last ,i doubt that the problem must be the address aliginging .

Does anyone have met or know the problem of address aligning between cfi (common flash interface ) and flash when using STRATIX II EP2S180's FLASH AM29LV128MH103REI ?

AM29LV128MH103REI has two mode ,word mode and byte mode .I use byte mode in my design .AM29LV128MH103REI has 16 data I/O pins DQ0~DQ15 .when you use the byte mode , only DQ0-DQ7 are active ,and the DQ15 is used as an input for the LSB (A-1) address function.And the datasheet say addresses are 22:A-1 in byte mode. shoud i connect like this ?cfi_address(0)-A-1 cfi_address(1)-A0.......(RIGHT ?)

BUT ,EP2S180 havenot assign phycal I/0 PINS for DQ15 at all!

how can i resolve it ? thanks for everone !

BEST WISHES!

Have you tried looking at the Appendix of the Nios II Flash Programmer, page 34:

thank you ,optikalillusion .I have already tried mthods that NIOS II Flash Programmer ,page 34 said .but it still not work.i am sure the physical connection is okey ,so i narrowed the problem to pin assignments.And the most doubtable pin assignment are the flash address pins.

thanks!
