Hi yaffsers, I download today's tarball of yaffs package. When I enter folder direct under yaffs, I got an error if I build the direct branch. - - - - make: *** No rule to make target `nand_ecc.c', needed by `nand_ecc.o'. Stop. - - - - If I removed "nand_ecc.o" from the Makefile, some error messages showed to me: - - - - /home/aubrey/temp/Development/yaffs/direct/yboot.c:269: undefined reference to `nand_calculate_ecc' yboot.o(.text+0x4f7):/home/aubrey/temp/Development/yaffs/direct/yboot.c: 270: undefined reference to `nand_correct_data' yboot.o(.text+0x50b):/home/aubrey/temp/Development/yaffs/direct/yboot.c: 271: undefined reference to `nand_calculate_ecc' yboot.o(.text+0x526):/home/aubrey/temp/Development/yaffs/direct/yboot.c: 272: undefined reference to `nand_correct_data' - - - - Thanks for anyone to help me out. -Aubrey
