I get this error message every time I try to scan for something giving a range for the address. Like:



Those settings give that error, and if the start box is changed back to 00... etc it works again. No extra settings are checked or anything, and I'm trying to range find cause unknown initial scan takes way too long (probably little ram).

"Scan error: no readable memory found" means that CE can't read any memory in the region you've specified. In case you don't know what this means for you, I'll just say your start and stop bounds are too big.

I'm pretty sure most CPUs nowadays only allow 48-bit addressing in a 64-bit virtual address space. The upper 16 bits are unnecessary at this point since 256 TB of virtual memory is more than enough.

If you're attached to a 32-bit process, you should be smart enough to figure out what you're doing wrong yourself.

Just look at the error.

"Scan error: no readable memory found"

There is no readable memory in the bounds you've specified. As I said previously, this is because there should be no memory between 2^48 and 2^64.

Change the "Start" and "Stop" address bounds to something else. For example, change the "Stop" to 2^47-1, 7FFFFFFFFFFF, and change "Start" to something less than that.


Setting it further than 2^63 might have made it overflow back into a normal memory region. I'd consider that a bug in this case as it's not what you should be doing.

Did you add a process to begin with?
