Problems launching Nios II ISS

avatar,

the iss doesn't model flash components, hence the failure to load data into it during initialisation.

If you're would like to simulate flash as a block of memory instead, then you can edit the ptf file :

. go the the flash module eg. Module ext_flash

. edit the iss_module_name parameter value to read "altera_memory" ie.

iss_model_name = "altera_memory";

The iss supports simulation of the following peripherals:

. memory (ram/rom)

. avalon timer

. avalon jtag uart

. avalon uart

Accesses to unsupported peripherals will be ignored.
