Created Saturday 11 August 2012
从NOR Flash启动的话，需要将uboot, uImage，rootfs和dtb分别烧写到flash中。
启动时，只需将后面三者在flash中的起始地址传给bootm即可。具体过程如下：

====== 使用minicom向uboot下载文件 ======
Created Friday 10 August 2012
1. 设置好minicom的环境，如[[../../Error_Notes/下载错误/minicom乱码.txt]]
2. 复位开发板，启动uboot，在命令行界面输入loady命令，这是uboot处于文件下载等待状态。注意，必须先在minicom环境中与uboot相连而且使uboot处于
等待状态后才进行第三步.
3. 如下配置minicom的文件传输：
a. Ctrl + a进入minicom的配置环境。
b. 按s, 进入send file配置界面。
c. 选择列表中的ymodem协议模式
d. 这时出现“待上传的文件选择列表”菜单，使用上下键在目录项中移动，按两次空格进入光标所在的目录，然后按一次空格选中文件，确保[Okey]被选中
然后按回车。 这时会出现文件上传的进度窗口。

====== 制作jffs2根文件系统 ======
Created Saturday 11 August 2012
http://www.embedu.org/Column/Column17.htm
JFFS2是Flash上应用最广的一个日志结构文件系统。它提供的垃圾回收机制，不需要马上对擦写越界的块进行擦写，而只需要将其设置一个标志，标明为脏块，当可用的块数不足时，垃圾回收机制才开始回收这些节点。同时，由于JFFS2基于日志结构，在意外掉电后仍然可以保持数据的完整性，而不会丢失数据。
本文阐述如何在nand flash上实现JFFS2根文件文件系统。实验环境是：FS2410开发平台及ubantu7.04主机环境。
**1．下载MTD工具包**
制作jffs2根文件系统需要使用__mtd-utils__软件包提供的**mkfs.jffs2**命令，所以先要安装该软件包。完成此步骤后，系统中就有了mkfs.jffs2的工具。注意：这个工具不同于mkfs.ext2工具，它只能制作相应的JFFS2文件系统的镜像，__而不具有进行格式化的功能__，而mkfs.ext2具备这以上两种功能。然后用这个工具就可以制作JFFS2文件系统的镜像了。
**2、制作JFFS2文件镜像**
实验平台用到的nand flash 是K9F1208，在制作镜像过程添加的参数需要和它对应。
farsight#mkfs.jffs2 -r /source/rootfs -o rootfs.jffs2 **-e 0x4000** **--pad=0x800000** -n
这样就会生成一个8M大小的rootfs.jffs2的镜像，它也正是JFFS2文件系统的镜像，关于这个命令行里的选项的内容，可以用man a mkfs.jffs2命令来查看内容。
也可以参考：[[../../Error_Notes/jffs2_scan_eraseblock()_Magic_bitmask_0x1985_not_found_at.txt]]
JFFS2 维护了几个链表来管理擦写块，根据擦写块上的内容，一个擦写块会在不同的链表上。具体来说，当一个擦写块上都是合法(valid)的节点时，它会在 clean_list 上；当一个擦写块包含至少一个过时(obsolete)的节点时，它会在 dirty_list 上；当一个擦写块被擦写完毕，并被写入 CLEANMARKER 节点后，它会在 free_list 上。而当你在挂载这个文件系统的时候，如果出现CLEANMARKER node found at 0x0042c000 has totlen 0xc != normal 0x0的警告的时候，可以加一个“-n”的选项，这个主要是由于针对Nand Flash不需要在每个擦除块的开始写入CLEANMARKER 节点。
**3、设置内核启动参数**
本处用的bootloader是U-BOOT.所以在U-BOOT的命令终端设置如下：
FS2410#setenv bootargs __root=/dev/mtdblock2 rootfstype=jffs2__ rw console=ttySAC0,115200
__注意：bootargs参数是传给kernel的启动参数，设备分区mtdblock2所对应的flash空间是通过设备树文件指定的，在内核启动前要通过uboot等工具将制作的__
__jffs2文件系统映像烧写到该空间中。__
**4、配置内核支持JFFS2文件系统**
File systems ---> Miscellaneous filesystems --->
<*>JournallingFlash File System v2 (JFFS2) support
[*]JFFS2write-bufferingsupport
[*]AdvancedcompressionoptionsforJFFS2
[*]JFFS2ZLIBcompressionsupport
[*]JFFS2RTIMEcompressionsupport
[*] JFFS2 RUBIN compression support
**5、下载rootfs.jffs2镜像**
通过uboot命令行，将jffs2映像__下载到Nand Flash第二个分区（Flash分区情况是由dtb文件指明的）__。
FS2410#nand erase 200000 800000
FS2410#nand write.jffs2 300008000 200000 800000
这里说明下关于nand flash操作的几个常用命令的含义
nand write：向Nand Flash写入数据，如果NandFlash相应的区域有坏块，则直接报错。
nand write.jffs2：向Nand Flash写入数据，如果NandFlash相应的区域有坏块，可以跳过坏块。
nand read：读取Nand Flash相应区域的数据，如果NandFlash相应的区域有坏块，则直接报错。
nand read.jffs2s：读取Nand Flash相应区域的数据，如果NandFlash相应的区域有坏块，将对应坏块区域的缓冲填充0xff，然后跳过此坏块继续读取。
nand read.jffs2：读取Nand Flash相应区域的数据，如果NandFlash相应的区域有坏块，直接跳过坏块。
具体的参考代码参看U-BOOT源码：common/cmd_nand.c文件。
下载完JFFS2文件系统镜像后，需要把Linux内核NandFlash的驱动关于第二个分区的大小改为8M（和镜像一样大，__对于MPC8315而言，由于使用了设备树文件，所以不需要修改内核__），否则会出现类似如下错误：
Freeing init memory: 124K
Warning: unable to open an initial console.
Argh. Special inode #171 with mode 0xa1ff had more than one node
Kernel panic: No init found. Try passing init= option to kernel.
Argh. Specia inode #63 with mode 0xa1ff had more than one node

Argh. Special inode #67 with mode 0xa1ff had more than one node
Returned error for crccheck of ino #67. Expect badness...
Argh. Special inode #68 with mode 0xa1ff had more than one node
到此，一个JFFS2文件系统的镜像制作成功。可以启动系统并测试JFFS2的性能了。还有一种制作JFFS2文件系统镜像的方法，在制作镜像的参数中可以不加—pad选项，过程如下：
farsight#mkfs.jffs2 -r /source/rootfs -o rootfs.jffs2 -e 0x4000 -n
启动开发板烧写rootfs.jffs2镜像
FS2410#**nand erase 200000 800000/**/(注意把整个存放文件系统的分区全部给擦除)。
FS2410#**nand write.jffs2 30008000 200000 31a28c**//(必须是rootfs.jffs2的实际大小。如果是你写成了4M，那么分区的其余部分JFFS2文件系统将无法识别)。

====== 制作jffs2根文件系统并将其烧写到flash中 ======
Created Saturday 11 August 2012
1. **配置ltib**，指定生成的目标文件系统映像类型为__jffs2__，同时__erase block 大小与Flash datasheet上指定的一致__（这里为16KB）：
--- Choose your root filesystem image type │ │
│ │ Target image: __(jffs2)__ ---> │ │
│ │ [ ] Run a command after building the target image │ │
│ │ __(16)__ jffs2 erase block size in KB │ │
│ │ [ ] read-only root filesystem │ │
│ │ (512k) tmpfs size │ │
│ │ (/tmp /var) Place these dirs in writable RAM │ │
│ │ () rootfs target directory
2. **复位开发板，进入uboot命令行状态**
**3. 将生成的rootfs.jffs2映像下载到内存中**
=> tftp 1000000 rootfs.jffs2

**4.按照dtb中的Flash分区配置，擦出将要保存rootfs.jffs2文件的flash存储区域**
例如对于mpc8315dtb-defaults.dts中的配置如下：
flash@0,0 { #NOR flash
#address-cells = <0x1>;
#size-cells = <0x1>;
compatible = "cfi-flash";
reg = <0x0 0x0 0x800000>;
bank-width = <0x2>;
device-width = <0x1>;
u-boot@0 {
reg = <0x0 0x100000>;
read-only;
};
fs@100000 {
reg = <0x100000 0x400000>;
};
kernel@500000 {
reg = <0x500000 0x200000>;
};
dtb@700000 {
reg = <0x700000 0x100000>;
};
};
nand@1,0 {
#address-cells = <0x1>;
#size-cells = <0x1>;
compatible = "fsl,mpc8315-fcm-nand", "fsl,elbc-fcm-nand";
reg = <0x1 0x0 0x2000>;
u-boot@0 {
reg = <0x0 0x100000>;
read-only;
label = "U-Boot-NAND";
};
__jffs2@100000 {__
reg = <0x100000 0x800000>;
label = "JFFS2-NAND";
};
ramdisk@900000 {
reg = <0x900000 0x400000>;
label = "Ramdisk-NAND";
};
reserved@d00000 {
reg = <0xd00000 0x1000000>;
label = "Reserved-NAND";
};
kernel@1d00000 {
reg = <0x1d00000 0x200000>;
read-only;
label = "Kernel-NAND";
};
dtb@1f00000 {
reg = <0x1f00000 0x100000>;
read-only;
label = "DTB-NAND";
};
};
当我们想将rootfs.jffs2烧写到label为"JFFS2-NAND"的NAND Flash区域时，可以使用下列的擦出命令：
**=> nand erase 100000 800000**
NAND erase: device 0 offset 0x100000, size 0x800000
Bad block table found at page 65504, version 0x01

nand_read_bbt: Bad block at 0x000b4000

OK
=>
5. **将下载到内存0x1000000开始的大小为$filesize的rootfs.jffs2文件烧写到NAND Flash 0x100000开始的地方。**
=> nand write 1000000 100000 $filesize
NAND write: device 0 offset 0x100000, size 0x41c000
4308992 bytes written: OK
=>
6. **设置kernel命令行参数，指定root为刚才烧写到的nand partition。**
=> setenv bootargs __root=/dev/mtdblock5 rw rootfstype=jffs2__ console=ttyS0,115200
7. **设置uboot自动启动时的bootcmd参数，注意fe500000和fe700000两个flash内存区域事先已经用uboot命令行写入了uImage和mpc8315.dtb文件。**
=> setenv bootcmd bootm fe500000 - fe700000
=> saveenv __#这样下次启动时，如果过了6秒时间uboot会按照bootcmd环境变量的值启动。__
=>boot

====== 烧写固件到NAND然后启动时读取 ======
Created Saturday 11 August 2012
经过实验，板子的NOR Flash可以正常启动，但是从NAND Flash中启动失败。但是NAND Flash可以正常工作。
所以，可以将NOR Flash作为启动设备，只保留uboot(或再加上uImage)，而将其余的固件内容放到NAND中，
由uboot启动时读取到内存中。具体步骤如下：
1. **查看uboot提供的nand命令语法**
=> help nand
nand info - show available NAND devices
nand device [dev] - show or set current device
nand read - addr off|partition size
nand write - addr off|partition size
read/write 'size' bytes starting at offset 'off'
to/from memory address 'addr', skipping bad blocks.
nand erase [clean] [off size] - erase 'size' bytes from
offset 'off' (entire device if not specified)
nand bad - show bad blocks
nand dump[.oob] off - dump page
nand scrub - really clean NAND erasing bad blocks (UNSAFE)
nand markbad off - mark bad block at offset (UNSAFE)
nand biterr off - make a bit error at offset (UNSAFE)
**=> nand info** #查看nand设备信息
Device 0: NAND 32MiB 3,3V 8-bit, sector size 16 KiB
**=> nand erase #擦出整个设备(也可以指定擦出范围)**
NAND erase: device 0 whole chip

====== ramdisk部署--通过flash ======
Created Saturday 11 August 2012
一、NOR Flash方式:
这种部署方式是将ramdisk格式的根文件系统、内核、设备树烧写到flash中，然后复位后摘bootcmd中指定三个文件在flash中起始地址即可。适合与较小的固件。
首先要规划NOR Flash的空间安排，在mpc8315dtb-default.dts文件中，安排如下：
flash@0,0 {
#address-cells = <0x1>;
#size-cells = <0x1>;
compatible = "cfi-flash";
reg = <0x0 0x0 0x800000>;
bank-width = <0x2>;
device-width = <0x1>;
u-boot@0 {
reg = <0x0 0x100000>;
read-only;
};
fs@100000 {
reg = <0x100000 0x400000>;
};
kernel@500000 {
reg = <0x500000 0x200000>;
};
dtb@700000 {
reg = <0x700000 0x100000>;
};
};
由于MPC831ERDB上的NOR Flash只有8MB空间，因此三个文件的大小加起来不能超过8MB。由于使用ramdisk方式时，是使用SDRAM作为根文件系统，所以
实际为这三个文件分配空间时可以任意，只要够用就行。
二、 NAND Flash方式：
当固件较大时，可以将其烧写到容量较大的NAND Flash中，然后启动时将这三个文件读取到内存中(通过nand read命令)启动。__注意如果是NOR Flash则bootm的三个参数可以直接是文件在NOR Flash中烧写的首地址，因为NOR Flash支持在芯片执行(XIP).__
可以将NOR Flash和NAND Flash烧写相结合的方式启动，如将较小的uImage和dtb烧写到NOR中，将较大的rootfs烧写到NAND中，然后在bootm前将NAND 中的文件读到内存中即可。
