Hello I have troubles with deleting files. I am doing delete and create file often. All is good, but after delete and create approximately 200 files I have not ram memory. For testing I have 2MB ram(it is much). Yaffs call yaffsfs_mallo, but yaffsfs_free is not call. Where I have error? Example code: Handle = yaffs_open("data/file1.dat",O_CREAT | O_RDWR, S_IREAD | S_IWRITE); . . . yaffs_close(Handle); . . . . yaffs_unlink("data/file1.dat"); yaffs_unlink function is for delete file? Acording to all information yes. Thank you for response. MS
