Hi,

I have the same problem with my custom board. I use quartus 9.1sp1.

I have errors in my external sram :

"Cannot insert breakpoint 3.

Error accessing memory address 0x2205730: Unknown error 4294967295."

Or

"symbol is not available",

Or watchdog timeout in debug mode : "Execution is suspended because of error. Watchdog has expired. Target detached.".

Did you find the cause of your problems ? How do you fix it ?

Thanks for you help.
