Does Nios II economy core have no hardware breakpoints?

I have ran into an issue with nios 2 economy core. I am unable to debug the code when running from flash as the eclipse crashes in the startup code

_start () at HAL/src/crt0.S:304
304 movhi sp, %hi(__alt_stack_pointer)
Warning:
Cannot insert breakpoint 1.
Cannot access memory at address 0x80270

I am able to run the code and I can see the hello world message on the console. But I am unable to debug the code.

Is hardware breakpoints with flash only possible with Nios II fast core?
