Sharath new problem had to comment calls to function yaffs_FlushFilesChunkCache(in) in function int yaffs_FlushFile(yaffs_Object *in) & int yaffs_ResizeFile(yaffs_Object *in, int newSize) I am unclear why this was needed. I find no problems. What Makefile defines are you using? previous 1)Line 1. That seems odd. Why are you doing that? Please quote the commented line in case our linecounts differ. mkyaffsimage.c:229: structure has no member named `sum' make: *** [mkyaffsimage.o] Error 1 [skumar@embedded_linux utils]$ not solved: line to be commented oh->sum = yaffs_CalcNameSum(oh->name); You are quite right. I haven't rebuilt mkyaffsimage in quite a while. The sum header item has been removed. This means the CalcNameSum function I added can also go (Charles?).
