Using cable "ByteBlasterII [LPT1]", device 1, instance 0x00 Resetting and pausing target processor: OK Reading System ID at address 0x00404040: verified No CFI table found at address 0x00200000 Leaving target processor paused Can anyone help me in sorting out this issue? THS! Handsome15 Replies
Altera_ForumHello handsome, WP/ACC could be left floating, because there is a pull up resitor inside.
You have set the base address to 0x00000000, correct ? Set t(setup), t(hold) and t(wait) to 200ns, we can increase the speed later! Have you connected pin BYTE to VCC or GND ??? It's really important to know that!- Altera_Forum
Hi,Maestro666,as your advice,i typed the commond----nios2-flash-programmer --base=0x00000000 --debug
It still shows that:No CFI table found at address 0x00000000. I locked the base_address of flash,make it to 0x00000000. BTW,I made pin--WP/ACC and NC(13-pin) floating. t(setup)=50ns;t(wait)=40ns;t(hold)=35ns; Waiting for your reply! Thanks! - Altera_Forum

Have you selected "Byte" or "Word" mode for your flash ??? Type following command in nios2 command console:
nios2-flash-programmer --base=0x00200000 --debug If you see the cfi table, then you can be shure that your flash is correct connected. - Altera_Forum
Try running the nios2-flash-programmer.exe from the nios2 command console with the --debug option and look at the CFI table. The most likely cause of this problem is the address lines are off by one i.e. the SOPC A0 bit should go to the A(-1) bit of the Flash.
