Dear Furquan, it seems to me that there is a slight formal mistake in calculation of dst_size, which causes the ifwitool to crash.
I was able to fix it on my own with the following patch, which moves the closing bracket one line ahead: diff --git a/util/cbfstool/ifwitool.c b/util/cbfstool/ifwitool.c index 7fca542..a1365bd 100644 --- a/util/cbfstool/ifwitool.c +++ b/util/cbfstool/ifwitool.c @@ -1679,8 +1679,8 @@ static enum ifwi_ret ifwi_dir_replace(int type) } struct buffer dst; - size_t dst_size = buffer_size(&ifwi_image.subpart_buf[type] + - buffer_size(&b) - s->e[i].length); + size_t dst_size = buffer_size(&ifwi_image.subpart_buf[type]) + + buffer_size(&b) - s->e[i].length; size_t subpart_start = s->e[i].offset; size_t subpart_end = s->e[i].offset + s->e[i].length; Could you please confirm if this correction is okay?
