When? In 'ubi_write_fastmap()' when forming the FM pool data structures? I think you can just add a function like this to wl.c: int ubi_wl_get_peb_info(int pnum, struct ubi_wl_peb_info *pebinfo) Yoy will give it the PEB number you are interested in, it will return you the information you need in 'pebinfo'. The information will contain the EC, the state (used, free, etc). If you need just the EC, then you do not even need the ubi_wl_peb_info data structure. Then you just iterate over all PEBs and fill the FM pool data structures. Would something like this work?
