与正常的启动代码对比了，发现没有识别spiflash，但是我在内核里已经做了相关配置：

不知道哪里还有毛病？是需要增加spiflash的驱动在kernel里面吗？

EddyZhan · 2018-05-11 22:10:02

我就是按照nano.lichee.pro的里面做的，然后对照zero spiflash 教程做的：
http://zero.lichee.pro/%E7%B3%BB%E7%BB%9F%E5%BC%80%E5%8F%91/SPI_flash_build.html#id16

晕哥说：

看起来是rootfs有问题，
u-boot的bootargs 是什么？
你也是主线u-boot + bsp linux ?

EddyZhan · 2018-05-11 22:11:19

bootargs 是这个： console=ttyS0,115200 earlyprintk panic=5 rootwait mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,4M(kernel)ro,-(rootfs) root=31:03 rw rootfstype=jffs2

EddyZhan · 2018-05-11 22:13:08

正常启动的内核能打印出来这个：
[ 0.747219] m25p80 spi32766.0: w25q128 (16384 Kbytes)

[ 0.764037] p4 : size=ffffffff

所以我怀疑是linux内核spi驱动问题。。

EddyZhan · 2018-05-11 22:16:56

我直接在 include/configs/suniv.h里改的,f1c100s用的是这个头文件吧。

晕哥说：

配置uboot默认环境变量
在文件 include/configs/sun8i.h 中添加默认bootcmd和bootargs的环境变量设置，注意添加的位置在“ #include <configs/sunxi-common.h> ”的前边。
貌似这里有问题，应该改成 ./include/configs/sun4i.h
可能没有把 u-boot 的bootargs传进来？

晕哥说：

为了确定一下，你进入 u-boot 命令行，
==> printenv bootcmd
==> printenv bootargs

EddyZhan · 2018-05-11 22:32:45

这的√上了，我取消一下重新编译一下看看。

看下这个帖子，有没有启发？

------------------------------------------------------------
我搜了一下， Booting Linux with rootfs on a JFFS2 File System
看是不是因为这样:

你是不是勾上了 initramfs/initrd 这个根文件系统？

EddyZhan · 2018-06-14 16:41:23

确实主要原因是内核里对SPIflash的支持问题，按照坛友的做法目前已经启动正常了。

EddyZhan · 2018-06-14 16:42:56

我是直接手动修改的.config文件。
参数传递，在uboot里直接用的bootargs，参考的zero spiflash烧写步骤，需要把spi32776.0改成spi0.0.

三贪猪说：

几乎熬了个通宵，终于找到原因了并解决问题了：官网下载的config文件，开错了全志的spi控制器开关，正确的配置是# CONFIG_SPI_SUN4I is not set
CONFIG_SPI_SUN6I=y(看来f1c100s用的是新版本的spi控制器)。修改后内核可以正确识别到spi flash了。另外，官网页面上还有个问题， uboot的bootargs 参数设置中， root=/dev/mtdblock3必须要修改为root=31：3，否则无法正确加载rootfs。修改以上两点后可以正确启动到控制台了。云盘中的sdk包4.13和docker中的4.15版本均是如此修改。
