Verify problem while runing on Nios II hardware

[Altera_Forum]

Hi there, 

 when i try to run my project on the Nios II hardware i get the following problem:  Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Processor is already paused Reading System ID at address 0x00070000: verified Initializing CPU cache (if present) OK  Downloading 00080000 ( 0%) Downloaded 43KB in 0.7s (61.4KB/s)  Verifying 00080000 ( 0%) Verify failed between address 0x80000 and 0x8ABDF Leaving target processor paused  I use the SRAM memory on DE1 board which has the Cyclone II FPGA. I also checked the base and end address for SRAM, and there is also no overlaping. The SRAM memory has the base address 00080000 and 0008ffff end address. I also use the on-chip memory for better perfomance. Have anyone an idea how to fix that problem?   Best regards!

Please check the Vector and Exception address are Pointing to? 

 Which QII verison are you using.

This problem may arise due to wrong pin assignment of an SRAM, so just check the pin assignment if any mistake is there.

Check for proper pin assignment of -  

1. Clock 2. Reset  Also check in 'system library properties' that you are using on chip memory, and not sram, as program memory

It's happened to me once or twice because I forgot to use bidir pins for the data lines.

Thanks to all for your suggestions! I checked the pin assignment and it's perfect,there aren't problems. Also, the sys_lib is OK, I choose the SRAM memory as place for my code. The clock signal has the appropriate pin. 

 I fixed the problem, it was my mistake because I set the data bus as only output direction and now I use it as bidirectional direction and it works. Sometimes we have to look for the simpliest causes :rolleyes:. Before i fixed the problem I tried many options. Jakobjones gave me very good suggestions.   Again, thanks to all, Lightline you was right and if I wouldn't fix it before your suggestion were good!  Best regards!
