Remote Update with NIOS and EPCS

Hello,

Currenty I'm working on a Cyclone III to try Remote Update work. I've searched for a lot of information but couldn't find specifiek how to work. I'm trying to work with the altremote_update function and to access that block from NIOS with some PIO's defined in SOPC. With this method I can trigger the reconfiguration but now I want some data back from the data_out. But when I try that with an Input PIO to connect from the altremote_update function and read that from NIOS with this code:

IORD_ALTERA_AVALON_PIO_DATA(REMOTE_DATA_BASE)

When I try this the application crashed, so I'm wondering what am I doing wrong and is the way that I'm working correct?

Another problem is that I can't read the EPCS, I've defined the controller in SOPC and did all the pins in Quartus. But when I try to access the EPCS with this code

fd = alt_flash_open_dev(EPCS_FLASH_CONTROLLER_NAME);

Then fd is empty, so that will tell me that I can't access the EPCS, is that possible because I haven't yet got a licence? (The licence will arrive next week)

Thanks a lot!
