slacker,

you are right, and I have to correct my statement: the EPCS content isn't seen in the address space of NIOS. Direct accessible is the EPCS-controller. A memory dump at address 0 shows the code of 'epcs_controller_boot_rom.hex', the boot-copier ROM. But when compiling and linking my firmware, an .entry section is created, and a restart code automatically generated. And this is what the debugger expects, when downloading. So verifying will always fail.

Thanks for your help

Mike
