s3c2440 移值u-boot-2016.03 第6篇 支持mtd yaffs 烧写

1, 解决启动时的错误
Warning - bad CRC, using default environment
搜索发现 在 /tools/env/fw_env.c 中
/* 放在NAND FLASH 中 大小 128K 开始地址 */
#define CONFIG_ENV_IS_IN_NAND
#define CONFIG_SYS_ENV_SECT_SIZE (128 << 10)
#define CONFIG_ENV_OFFSET (256<<10)
#define CONFIG_ENV_SIZE CONFIG_SYS_ENV_SECT_SIZE

2, 添加 MTD
#define CONFIG_CMD_MTDPARTS /* Enable MTD parts commands */
#define CONFIG_MTD_DEVICE /* needed for mtdparts commands */
#define MTDIDS_DEFAULT "nand0=nand"
#define MTDPARTS_DEFAULT "mtdparts=nand:256k(uboot),"\
"128k(env),"\
"2m(kernel),-(fs)"

在 /common/board_r.c
man_loop 中添加
run_command("mtdparts default", 0);

擦除 nand flash
nand erase.part uboot
nand write 0x30000000 uboot

3, 下载试验

nfs 0x30000000 192.168.1.10:/nfs/fs.yaffs2
nand erase.part fs
nand write.yaffs 0x30000000 0x00260000 0x8607c0 (文件大小)
set bootargs noinitrd root=/dev/mtdblock3 init=/linuxrc console=ttySAC0
boot 启动

写入出错
Unknown nand command suffix '.yaffs2'

4, 支持 yaffs2

在 smdk2440.h 发现有个,配置后 #define CONFIG_YAFFS2

编译后,大了很多,有 335K ,菜单多了几个功能
yls - yaffs ls
ymkdir - YAFFS mkdir
ymount - mount yaffs
ymv - YAFFS mv
yrd - read file from yaffs
yrdm - read file to memory from yaffs
yrm - YAFFS rm
yrmdir - YAFFS rmdir
ytrace - show/set yaffs trace mask
yumount - unmount yaffs
ywr - write file to yaffs
ywrm - write file from memory to yaffs

试着挂载,失败,文档也没有找到,导致 u-boot 也非常大,换一种方法。

之前可以使用 #define CONFIG_CMD_NAND_YAFFS
对比了 u-boot 2013 2014 2015 都有这个功能, 但从 2015-10 移除了
参考u-boot 2015修改代码添加支持
/* 添加兼容 yaffs2 烧写支持 */
/include/configs/smdk2440.h
#define CONFIG_CMD_NAND_YAFFS
/cmd/nand.c
在543line:
if (strncmp(cmd, "read", 4) == 0 || strncmp(cmd, "write", 5) == 0) {
里面添加 622line:
#ifdef CONFIG_CMD_NAND_YAFFS
} else if (!strcmp(s, ".yaffs")) {
if (read) {
printf("Unknown nand command suffix '%s'.\n", s);
return 1;
}
ret = nand_write_skip_bad(nand, off, &rwsize, NULL,
maxsize, (u_char *)addr,
WITH_YAFFS_OOB);
#endif

/include/nand.h 101line: 添加
#define WITH_YAFFS_OOB (1 << 0) /* whether write with yaffs format. This flag * is a 'mode' meaning it cannot be mixed with * other flags */


/drivers/mtd/nand/nand_util.c 583line:
#ifdef CONFIG_CMD_NAND_YAFFS
if (flags & WITH_YAFFS_OOB) {
if (flags & ~WITH_YAFFS_OOB)
return -EINVAL;

int pages;
pages = nand->erasesize / nand->writesize;
blocksize = (pages * nand->oobsize) + nand->erasesize;
if (*length % (nand->writesize + nand->oobsize)) {
printf("Attempt to write incomplete page"
" in yaffs mode\n");
return -EINVAL;
}
} else
#endif

666line:
#ifdef CONFIG_CMD_NAND_YAFFS
if (flags & WITH_YAFFS_OOB) {
int page, pages;
size_t pagesize = nand->writesize;
size_t pagesize_oob = pagesize + nand->oobsize;
struct mtd_oob_ops ops;

ops.len = pagesize;
ops.ooblen = nand->oobsize;
ops.mode = MTD_OPS_AUTO_OOB;
ops.ooboffs = 0;

pages = write_size / pagesize_oob;
for (page = 0; page < pages; page++) {
WATCHDOG_RESET();

ops.datbuf = p_buffer;
ops.oobbuf = ops.datbuf + pagesize;

rval = mtd_write_oob(nand, offset, &ops);
if (rval != 0)
break;

offset += pagesize;
p_buffer += pagesize_oob;
}
}
else
#endif
{
这里要包含下面的部分。 最后 u-boot 改完后,会有大补丁。大家可以下载比较。
..............
}
编译后,252K
重新烧写出错
NAND write to offset 2a1000 failed -22 0 bytes written: ERROR
ops.mode = MTD_OPS_RAW; 这里也要改。

 

最终 完成了, 可以烧写 yaffs2 , 也能使用 NAND FLASH NOR FLASH ,网卡, u-boot 差不多结束了。
