Ubifs文件系统的制作和启动

写的不错，比较详细，比较有价值

昨天刚碰到问题，今天就看到周工的解决办法案例。

有帮助么？

请问一下：ti没有提供ubifs文件系统包，这样就不用自己制作了。 

附件是文档提及的制作步骤后生成的ubi.img，请解压后使用

你好，我就是按着这个这篇文档做的，到最后依然没有能加载ubifs。不知道什么原因。

简单描述一下我的情况：我们的板子是参考BBB做的，但没有eeprom，板子没有eMMC，而是用的nand flash，除此之外和BBB没多大区别了，现在用的这款主芯片是AM3352。在uboot中改了iic读取eeprom部分，改成BBB的信息，让内核以为是BBB，然后启动。用的SDK包是SDK6.0，内核是3.2，uboot是2013.01.01版本。目前做的SD卡启动，完全没有问题，uboot、kernel和文件系统都没有问题，能启动正常。

遇到了两个问题：1. SD卡启动uboot后，把MLO, u-boot.img, uImage, ubi,img烧写到板子的nand里，然后上电后，串口打印一直是CCC，并没有从nand启动，板子的SYSBOOT[4:0]=10011b,按说启动顺序是NAND-NANDI2C-MMC-UART，应该从nand启动的，但是没有。

2.从SD卡启动uboot后，烧写上面那些文件后，拔掉SD卡，输入boot命令，会从nand读取内核，并启动，但是到了要打开ubi0:rootfs的时候出错了，详细的启动打印信息在下面：

请各位前辈和TI的工程师，帮忙分析一下问题可能出在哪里，试了很多方法都不行，这里先谢谢各位大牛了。

看输出的信息感觉你NAND的分区有点问题呀:

Booting from nand ...

NAND read: device 0 offset 0x280000, size 0x600000
6291456 bytes read: OK

[ 1.437225] 0x000000280000-0x000000780000 : "Kernel"

这两处存在矛盾的地方，应该还是u-boot参数配置有问题

 其实是没有影响的，是有一点矛盾，就是在uboot中设置的kernel_size有点大，设置成0x500000就吻合了，默认是0x600000，没改，这么大也没事，内核多读了一些，不过那部分也没啥用，没啥影响，程序永远不会跑到那部分。

顺便在这边提一下，这个问题解决了，当时是以回复的模式发在这里了，后来新发了一个帖子，问题已解决，具体见：http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/73615.aspx?pi2132219853=1，谢谢大家的关注和热心帮忙。

周工，文档“Ubifs文件系统的制作和启动.pdf ”中选项 –F 写的有问题，应该是 -F

这样做出来的UBIFS，会出现只能加载一次的问题。

这2个不都是中横杠么，应该是输入法的不同吧？

你好，我这是按照你的方法做的ubi，但启动出现了下面的问题，请问这该怎么解决。

这个文档主要是针对NAND FLASH写的，如果是Nor FLASH，参数肯定是不一样的，也有可能用别的文件系统。

是否可以把u-boot和kernel放在NOR Flash中，文件系统放在NAND Flash中？如果是这样，文件系统该如何制作？

这篇文档就是针对放在NAND FLASH上的文件系统写的，和U-boot，kernel放在哪里无关。

你好，

我按照你的文档，第一步就是在u-boot当中加入那些宏定义，然后我进行编译的时候，出了一些问题：

make[1]: Leaving directory `/home/firelord/Documents/work4graduate20160219/sunubootgood/drivers/mtd/nand' make -C drivers/mtd/onenand/ make[1]: Entering directory `/home/firelord/Documents/work4graduate20160219/sunubootgood/drivers/mtd/onenand' arm-none-linux-gnueabi-ar crv libonenand.a make[1]: Leaving directory `/home/firelord/Documents/work4graduate20160219/sunubootgood/drivers/mtd/onenand' make -C drivers/mtd/ubi/ make[1]: Entering directory `/home/firelord/Documents/work4graduate20160219/sunubootgood/drivers/mtd/ubi' build.c:50:2: error: #error Malloc area too small for UBI, increase CONFIG_SYS_MALLOC_LEN to >= 512k make[1]: Leaving directory `/home/firelord/Documents/work4graduate20160219/sunubootgood/drivers/mtd/ubi' make[1]: Entering directory `/home/firelord/Documents/work4graduate20160219/sunubootgood/drivers/mtd/ubi' arm-none-linux-gnueabi-gcc   -Os  -fno-common -ffixed-r8 -msoft-float   -D__KERNEL__ -DTEXT_BASE=0x80700000 -I/home/firelord/Documents/work4graduate20160219/sunubootgood/include -fno-builtin -ffreestanding -nostdinc -isystem /home/sun/CodeSourcery/Sourcery_G++_Lite/bin/../lib/gcc/arm-none-linux-gnueabi/4.3.3/include -pipe  -DCONFIG_ARM -D__ARM__ -marm  -mabi=aapcs-linux -mno-thumb-interwork -march=armv7-a -Wall -Wstrict-prototypes -fno-stack-protector   \                 -o build.o build.c -c build.c:50:2: error: #error Malloc area too small for UBI, increase CONFIG_SYS_MALLOC_LEN to >= 512k make[1]: *** [build.o] Error 1 make[1]: Leaving directory `/home/firelord/Documents/work4graduate20160219/sunubootgood/drivers/mtd/ubi' make: *** [drivers/mtd/ubi/libubi.a] Error 2

and then I change the define of CONFIG_SYS_MALLOC_LEN . change is like below:

#define (CONFIG_ENV_SIZE + (768 * 1024)) 

OR #define CONFIG_SYS_MALLOC_LEN (2 << 20) 

OR #define CONFIG_SYS_MALLOC_LEN (4 << 20)

虽然我能够成功进行u-boot的编译了，但是编译好的u-boot放到nand之后，并不能正常工作，甚至都没有办法在串口当中收到任何信息。

你觉得这会是什么问题呢？

你用的是哪个Linux的版本，为啥我看到了 arm-none-linux-gnueabi-gcc

我们SDK 6.0前用的是arm-arago-linux-gnueabi-gcc, 之后用的是arm-linux-gnueabihf-gcc，也就是Linaro的，你用的是哪个？编译的是335么

我的核心芯片是TMS320DM8168，使用的是ezsdk5.05.02.00版本。

上述的配置和描述都是基于AM335x平台的，并不适用于DM8148。各个的SDK都不相同。建议你把DM8148的问题post到达芬奇论坛。

针对其他的处理器平台，我没有做过验证，但是我觉得可以做个借鉴。

$ mkfs.ubifs –F -q -r /home/usr/fs -m 2048 -e 126976 -c 2047 -o ubifs.img

该指令后，报错Error: max_leb_cnt too low (2556 needed)

根据那个文档再检查下参数配置。

利用工具将文件系统[arago-base-tisdk-image-am335x-evm.tar.gz]生成ubi.img，文件大小是45.5M不是25M；

通过这个帖子http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/62170.aspx将相关文件烧入nand中，

其中nandecc hw 2这个命令没有输，

设置#setenv bootargs 'console=ttyO0,115200n8 noinitrd ip=off mem=256M
rootwait=1 rw ubi.mtd=7,2048 rootfstype=ubifs root=ubi0:rootfs init=/init'

boot启动后打印如下信息：

[ 19.312043] VFS: Cannot open root device "ubi0:rootfs" or unknown-block(0,0)
[ 19.319542] Please append a correct "root=" boot option; here are the available partitions:
[ 19.328549] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
[ 19.337363] Backtrace:

上边的问题已解决。

原因是烧写ubi.img不完整，扩大烧写nand空间就好了。

新的问题是：我想将自己SD卡中的文件系统生成ubifs文件系统，执行如下指令：

$ mkfs.ubifs –F -q -r /home/usr/fs -m 2048 -e 126976 -c 2047 -o
ubifs.img

总是报错：Error: max_leb_cnt too low (2991 needed)

请问该怎么办

没太明白什么意思，你之前做的文件系统是基于SDK自带的文件系统解压后做的么？

SDK中有两个文件系统压缩包：

1  arago-base-tisdk-image-am335x-evm.tar.gz (17.7MB)

2  tisdk-rootfs-image-am335x-evm.tar.gz (270.4MB)

制作的UBI文件系统是通过第1个，通过第2个一直报错；

而SD卡中的文件系统是第2个，应用开发阶段仍然采用SD的方式，最后才用NAND方式，

以后会遇到的问题是：应用开发阶段用的文件系统（第2个），无法制作UBI文件系统；

还想请教：这两个文件系统差别在哪里？

小的是精简的文件系统，大的是带显示的大而全的文件系统，你们的应用用那个精简的就可以。

你是同样的操作命令，大的文件系统就不行么？是不是参数的问题

您指的参数是“$ mkfs.ubifs –F -q -r /home/usr/fs -m 2048 -e 126976 -c 2047 -o ubifs.img”红色的部分参数吗？

这些参数是根据NAND 型号定的，我的板子和开发板的NAND是相同型号的，所以应该不是参数的问题。

大的文件系统制作出来的UBI文件系统应该也很大吧，应该会大于NAND的容量（256MB）吧，这样的话也就没啥意义了。

是的，那个大的文件系统，里面包含了很多多媒体文件，还有显示图形库，你们都用不到。

你们用那个小的就可以了。

周工，关于以下两条指令：

$ mkfs.ubifs -F -q -r /home/usr/fs -m 2048 -e 126976 -c 2047 -o ubifs.img

$ ubinize -o ubi.img -m 2048 -p 128KiB ubinize.cfg

下面两个选项要请教下：

1. -q：我查了最新的mkfs.ubifs代码，没有该选项，它是做什么用的？

2. -c 2047：我看文档中的说明是“文件系统所占用的最大block数，一般小于等于block count -1”。我的是Android系统，Nand Flash共256MB（2048块），MLO、u-boot和uImage占用了前7MB的空间，也就是说，ubifs的可用空间是249MB（1992块），那么，这里我应该设置成小于等于2047，还是小于等于1991？

我那个文档也是参考网上社区的资料验证和总结的，都有参考资料的链接，你可以看一下。

“参考资料的链接”在哪里？文档里没有啊，请在这里列一下呗！谢谢！

不好意思，文档确实忘记了加参考资料链接地址，我是照着下面的文档做的：

http://processors.wiki.ti.com/index.php/UBIFS_Support

请问下，在按照文档中的说明编译时，编译的是PC端工具吗？(使用的是gcc)

我的ubuntu下设置了CC环境变量为“arm-2010.09/bin/arm-none-linux-gnueabi-”，结果配置zlib时出错：

这个“arm-2010.09/bin/arm-none-linux-gnueabi-“的交叉编译工具太老了，要换成SDK06里的交叉编译工具：

http://processors.wiki.ti.com/index.php/Processor_Linux_SDK_GCC_Toolchain

咨询下，根据文档，制作的 UBI 文件系统，是成功启动了，但是存在一些疑问，望解答！

内核的分区为八个分区，分别是 ：

static struct mtd_partition am335x_nand_partitions[] = {
/* All the partition sizes are listed in terms of NAND block size */
{
.name = "SPL",
.offset = 0, /* Offset = 0x0 */
.size = SZ_128K,
},
{
.name = "SPL.backup1",
.offset = MTDPART_OFS_APPEND, /* Offset = 0x20000 */
.size = SZ_128K,
},
{
.name = "SPL.backup2",
.offset = MTDPART_OFS_APPEND, /* Offset = 0x40000 */
.size = SZ_128K,
},
{
.name = "SPL.backup3",
.offset = MTDPART_OFS_APPEND, /* Offset = 0x60000 */
.size = SZ_128K,
},
{
.name = "U-Boot",
.offset = MTDPART_OFS_APPEND, /* Offset = 0x80000 */
.size = 15 * SZ_128K,
},
{
.name = "U-Boot Env",
.offset = MTDPART_OFS_APPEND, /* Offset = 0x260000 */
.size = 1 * SZ_128K,
},
{
.name = "Kernel",
.offset = MTDPART_OFS_APPEND, /* Offset = 0x280000 */
.size = 40 * SZ_128K,
},
{
.name = "File System",
.offset = MTDPART_OFS_APPEND, /* Offset = 0x780000 */
.size = MTDPART_SIZ_FULL,
},

也就是 MTD7 为 File System，整个文件系统的空间大约是 1000MB 大小空间

系统成功挂载 UBI 文件系统之后，查看分区 ：

cat /proc/mtd
dev: size erasesize name
mtd0: 00020000 00020000 "SPL"
mtd1: 00020000 00020000 "SPL.backup1"
mtd2: 00020000 00020000 "SPL.backup2"
mtd3: 00020000 00020000 "SPL.backup3"
mtd4: 001e0000 00020000 "U-Boot"
mtd5: 00020000 00020000 "U-Boot Env"
mtd6: 00500000 00020000 "Kernel"
mtd7: 1f880000 00020000 "File System"
mtd8: 1e349000 0001f000 "rootfs"

变成了九个分区，在内核指定的 "File System"后面，又多了一个  "rootfs"。而且计算可以知道，  "rootfs" 大约从   "File System" 获得了一般的空间大小，大约为 483MB。

这个是为什么呢？这种现象是正常的么？我应该如何去理解？还是说，我应该讲修改我的内核分区?

Andriod系统还是Linux系统？

周工，我完全按照你的文档将arago-base-tisdk-image-am335x-evm.tar.xz解压到filesystem目录，然后按照如下指令进行编译：

mkfs.ubifs –F -q -r filesystem/ -m 2048 -e 126976 -c 2047 -o ubifs.img
ubinize -o ubi.img -m 2048 -p 128KiB ubinize.cfg

ubinize.cfg内容如下：

[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=200MiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize

编译出来的ubi.img能正常加载，但是大小是120M，我看你上传的ubi.img才25.2M，我应该怎么做呢？是把解压出来的文件里删除不需要的东西来缩小么？

您好，最近我在用am5728   开发板装有一块nand芯片，型号如下：

nand型号Micron MT29F4G08ABAEAWP

nand: 512 MiB, SLC, erase size: 256 KiB, page size: 4096, OOB size: 224

想要挂载ubifs文件系统。

使用 的SDK版本：ti-processor-sdk-linux-am57xx-evm-03.03.00.04

在交叉编译器中有mkfs.ubifs 和ubinize两个工具，

请问还需要自己编译这两个工具吗？可以直接使用这两个工具吗？

我使用交叉编译器中的这两个工具制作fs出现如下错误提示：

mkfs.ubifs -F -r rootfs/ -m 4096 -e 253952 -c 1990 -o ubifs.img

ubinize -o ubi.img -m 4096 -p 256KiB -s 1024 -O 4096 ubinize.cfg

你的问题解决了吗？ 我遇到了跟你一样的错误

请问下,我使用的sdk6.0的,现在制作UBI文件系统过程中,通过这个命令mkfs.ubifs -F -q -r /home/usr/fs -m 2048 -e 126976 -c 2047 -o ubifs.img ,会提示没有F的这个,我看里面的确实没有-F 只有-f , 这个跟我下载的 mkfs.ubifs这个命令有关么?

期待的你的回复

以我调试的经验，通常您可以先把SDK里的.ubi文件直接烧写到你的NAND里面，看看正常不正常，如果不正常很可能您的系统配置会有一些问题。然后如果正常您先把这个ubi对应的压缩包解压后用你自己的工具进行压缩，如果这时候有问题大多数问题是制作UBI工具的问题或者是版本匹配或者是参数问题。这样排除就只能检查或者更换制作工具了。如果想通过一些打印信息能定位实际问题是比较耗时间的。

感谢你的回复!

嗯嗯,我把制作工具的版本换成了1.4.8的,然后从新生成文件系统文件,擦除下nandflash,重新烧写就可以的了.

感谢!
