您好，我换了100ask 上的mkyaffs2image 制作出来正好是2112的整数倍，烧写后却出现开始给的data abort 可能是什么造成的呢？以下是我的nand_util.c文件修改了的后面的部分：

复制代码 int nand_write_skip_bad(nand_info_t *nand, size_t offset, size_t *length,             u_char *buffer) {     int rval;     size_t left_to_write = *length;     size_t len_incl_bad;     u_char *p_buffer = buffer;          [u]if(nand->writeoob==1)     {         size_t oobsize = nand->oobsize;         size_t datasize = nand->writesize;                  int datapages = 0;                  if(((*length)%(nand->oobsize + nand->writesize)) != 0)         {             printf("*length=%d,pagesize=%d\n",*length,nand->oobsize+nand->writesize);             printf("Attempt to write error length data!\n");             return -EINVAL;         }                  datapages = *length/(datasize + oobsize);         printf("datasize+oobsize=%d,datapages=%d\n",datasize+oobsize,datapages);         *length = datapages * datasize;         left_to_write = *length;         nand->skipfirstblock=1;     }     /* Reject writes, which are not page aligned */ /*    if ((offset & (nand->writesize - 1)) != 0 ||         (*length & (nand->writesize - 1)) != 0) {         printf ("Attempt to write non page aligned data\n");         return -EINVAL;     } */[/u]    len_incl_bad = get_len_incl_bad (nand, offset, *length);     if ((offset + len_incl_bad) >= nand->size) {         printf ("Attempt to write outside the flash area\n");         return -EINVAL;     }     if (len_incl_bad == *length) {         rval = nand_write (nand, offset, length, buffer);         if (rval != 0) {             printf ("NAND write to offset %x failed %d\n",                 offset, rval);             return rval;         }     }     while (left_to_write > 0) {         size_t block_offset = offset & (nand->erasesize - 1);         size_t write_size;         if (nand_block_isbad (nand, offset & ~(nand->erasesize - 1))) {             printf ("Skip bad block 0x%08x\n",                 offset & ~(nand->erasesize - 1));             offset += nand->erasesize - block_offset;             continue;         }         /*added */         [u]if(nand->skipfirstblock==1)         {             nand->skipfirstblock=0;             printf("skip the first blcok!\n");             offset+=nand->erasesize - block_offset;             continue;         }[/u]        /*end add*/         if (left_to_write < (nand->erasesize - block_offset))             write_size = left_to_write;         else             write_size = nand->erasesize - block_offset;         rval = nand_write (nand, offset, &write_size, p_buffer);         if (rval != 0) {             printf ("NAND write to offset %x failed %d\n",                 offset, rval);             *length -= left_to_write;             return rval;         }         left_to_write -= write_size;         offset        += write_size; [u]//        p_buffer      += write_size;         if(nand->writeoob==1)     p_buffer += write_size + (write_size/nand->writesize*nand->oobsize);         else             p_buffer += write_size;[/u]     }     return 0; } /** * nand_read_skip_bad: * * Read image from NAND flash. * Blocks that are marked bad are skipped and the next block is readen * instead as long as the image is short enough to fit even after skipping the * bad blocks. * * @param nand NAND device * @param offset offset in flash * @param length buffer length, on return holds remaining bytes to read * @param buffer buffer to write to * @return 0 in case of success */ int nand_read_skip_bad(nand_info_t *nand, size_t offset, size_t *length,                u_char *buffer) {     int rval;     size_t left_to_read = *length;     size_t len_incl_bad;     u_char *p_buffer = buffer;     len_incl_bad = get_len_incl_bad (nand, offset, *length);     if ((offset + len_incl_bad) >= nand->size) {         printf ("Attempt to read outside the flash area\n");         return -EINVAL;     }     if (len_incl_bad == *length) {         rval = nand_read (nand, offset, length, buffer);         if (rval != 0) {             printf ("NAND read from offset %x failed %d\n",                 offset, rval);             return rval;         }     }     while (left_to_read > 0) {         size_t block_offset = offset & (nand->erasesize - 1);         size_t read_length;         if (nand_block_isbad (nand, offset & ~(nand->erasesize - 1))) {             printf ("Skipping bad block 0x%08x\n",                 offset & ~(nand->erasesize - 1));             offset += nand->erasesize - block_offset;             continue;         }         if (left_to_read < (nand->erasesize - block_offset))             read_length = left_to_read;         else             read_length = nand->erasesize - block_offset;         rval = nand_read (nand, offset, &read_length, p_buffer);         if (rval != 0) {             printf ("NAND read from offset %x failed %d\n",                 offset, rval);             *length -= left_to_read;             return rval;         }         left_to_read -= read_length;         offset       += read_length;         p_buffer     += read_length;     }     return 0; }

这个弄出来有58M 太大了吧？ 全部直接下到内存行吗？

呵呵。那主要的调试方法  是靠printf 来调试吗？有没有什么好的方法呢？
谢谢咯 kasim！

我先再网上查查资料！

我另外开了个贴 是关于制作方式的，麻烦版主看看，这种通过uboot的烧写估计我玩不成了！

有时间弄！不放弃！

  努力！
