mkfs_makevfat misaligned word/halfword writes

My target is LPC2148 (ARM7 from Philips) I had the problem of having an unreadable card after invoking mkfs_makevfat in mkfs.c. The issue is that the following lines make misaligned halfword/word writes on buf, thus overwriting adjacent bytes (such misaligned writes are forbidden on ARM7 architecture): /* Bytes/Sector */ *((unsigned short*)(buf+11)) = 512; //this puts a 0 in...
