检测到了 SPI FLASH，但是你的 cmdline 里面 parts 参数和 dts 里面均没有找到分区信息，所以就挂不起文件系统。

pqfeng · 2018-11-28 20:45:58

cmdline应该没有问题啊。 Kernel command line: console=ttyS2,115200 earlyprintk panic=5 rootwait mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,4M(kernel)ro,-(rootfs) root=31:03 rw rootfstype=jffs2 你说dts没有分区信息。dts本来就没有吧？？
没理解啊

没理解啊

我的意思是，根据log信息既没有在mtdparts分析出mtd分区信息，也没有在dts分析出mtd分区信息。

看下cmdline这行是不是错了字符?

pqfeng · 2018-11-28 21:15:39

我看了一下，仔细对了一下，没有问题，原来提是ttys0,我们现在的是s2,能正常打印，说明这个是没有问题的

晕哥 · 2018-11-28 21:23:21

现在确实看不出来 mtdparts 字符串有什么问题，晚点我帮你仔细核对.

或者你跟着一下 m25p80.c 的源码

看下为什么没有分析出分区来

pqfeng · 2018-11-29 08:36:55

我看起来，它是解析分区表时出错了。解析不出来。不知道这是为什么。

小猪佩奇 · 2018-12-14 14:34:06

楼主，问题解决了吗，我目前的问题跟你的一样

什么问题，把 log 贴出来吧.

添加 m25p80 驱动
设备树添加 spi flash
内核配置 config commandline parts (也可以配置设备树 dts parts)
bootargs 添加 mtdparts 命令行 (也可以在设备树配置mtdparts)
用 mkfs.jffs2 制作根文件系统, 并且烧录到前面mtdparts指定的位置.

小猪佩奇 · 2018-12-14 15:15:28

我使用w25q256，

添加 m25p80 驱动
已添加
设备树添加 spi flash

完全参考看云上的方法做的，https://www.kancloud.cn/lichee/lpi0/331844。

晕哥帮忙看一下~

初步估计, 很可能是 CONFIG_MTD_CMDLINE_PARTS=y 这项没勾上, 因为log没有发现分析出mtd分区.

确认只替换了 zImage, 用的是同一个 dtb 文件?

小猪佩奇 · 2018-12-14 15:40:13

我只替换了zImage，用的是您发的 V3s_W25Q256_MX25L256_Qt5.9.1.bin 里dd出来的kernel，

内核里这个也选中了<*> Command line partition table parsing

看不出问题了,

有这个log

m25p80 spi0.0: w25q256 (32768 Kbytes)

而没有解析出分区，可能是设备树没有配 spi flash

你把你的 dts 贴出来看下

这是我前几天做的flash镜像，你试一试: v3s_32M_flash.tgz

小猪佩奇 · 2018-12-16 15:24:08

感觉我的问题可能出在这
我uboot log，说

SF: Detected w25q256 with page size 256 Bytes, erase size 4 KiB, total 32 MiB
SF: Warning - Only lower 16MiB accessible, Full access #define CONFIG_SPI_FLASH_BAR

另外我的dts是

&spi0 {
	status = "okay";
	
	w25q128:w25q128@0 {
		compatible = "jedec,spi-nor";
		reg = <0x0>;
		spi-max-frequency = <16000000>;
		#address-cells = <1>;
		#size-cells = <1>;
	};
};

晕哥 · 2018-12-16 16:13:43

与这个没关系，只是告诉你不开启 CONFIG_SPI_FLASH_BAR, 那么uboot的访问范围只有16M

小猪佩奇 · 2018-12-17 10:30:03

那会不会是我镜像文件生成的有问题，我是这样操作的，（w25q256）
jffs2分区总空间是 32M-1M-64K-4M= 0x1AF0000

mkfs.jffs2 -s 0x100 -e 0x10000 -p 0x1AF0000 -d rootfs/ -o jffs2.img

dd if=/dev/zero of=flashimg.bin bs=32M count=1

把这两个参数先去掉: -s 0x100 -e 0x10000

小猪佩奇 · 2018-12-18 09:48:44

把这两个参数去掉，并换成4.13y的内核
现在可以启动了，感谢晕哥~

客气客气, 看到有朋友解决问题了很开森.

去掉这两个参数就是使用命令行的默认参数了 -s 0x1000 -e 0x10000,
s 是指 page size, 可能是驱动设置的page size 就是 0x1000

具体你可以用 beyond compare 比较二者生成的二进制文件和驱动代码。

另外我想除了USB烧写方式以外可不可以TF卡烧写，
把生成的bin文件放到TF卡里面，然后用mtd_write，或者dd是否可行，我试了一下目前是没写进去

busybox 内置的 flashcp 命令就是干这个活的:

flashcp mtd4.bin /dev/mtd4 -v

以上命令自动完成擦，写，校验
