Not correct. The first function writes to the memory, the last one maps it. Use it like unsigned int* data = prussdrv_map_extmem(&sequenceData); data[0] = 0815; ... Note: the ERam has a default size of 256 kB. In order to get 1 MB, you'll have to load the driver manually (8 MB max.). See this documentation <http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/_cha_memory.html> (section ERam at the bottom) for details.
