请问各位大佬，又遇到过内核起来之后，挂在不了跟文件系统的问题吗？

赋值了，不起效果，我再uboot的make menuconfig里面配置了console=ttyS0,115200 panic=5 rootwait root=/dev/mtdblock3 rw rootfstype=jffs2 同时关闭了默认配置，打开手动设置，设置成了上面这个console=ttyS0,115200 panic=5 rootwait root=/dev/mtdblock3 rw rootfstype=jffs2
但是不起效果，已经重新编译烧录，uboot命令行下打印参数信息，没有这个参数。然后我有换了一种方式，在uboot源码目录下 进入 ./include/configs/，修改 suniv.h ，添加了：
#define CONFIG_BOOTARGS "console=ttyS0,115200 panic=5 rootwait " \
" mtdparts=spi32766.0:1M(uboot),64k(dtb),4M(kernel),-(rootfs) " \
" root=/dev/mtdblock3 rw rootfstype=jffs2 "
还是不行。一样，大佬知道怎么回事吗？

现在唯一的办法就是uboot启动之后，自动添加参数：setenv bootargs 'console=ttyS0,115200 panic=5 rootwait root=/dev/mtdblock3 rw rootfstype=jffs2'
然后保存到uboot，这样子很麻烦。不能再烧录之前写死。

没有改错，所以很奇怪

我发现了一个问题，不管不怎么改变参数，编译出来的uboot始终没有变过，这是怎么回事？有两个参数，分别是：
#define CONFIG_BOOTCOMMAND "sf probe 0 50000000; " \
"sf read 0x80C00000 0x100000 0x4000; " \
"sf read 0x80008000 0x110000 0x400000; " \
"bootz 0x80008000 - 0x80C00000"
#define CONFIG_BOOTARGS "console=ttyS0,115200 panic=5 rootwait " \
" mtdparts=spi32766.0:1M(uboot),64k(dtb),4M(kernel),-(rootfs) " \
" root=/dev/mtdblock3 rw rootfstype=jffs2 "
有一个是可以传递的，有一个不行，但是我改变里面的"sf probe 0 50000000; " 为"sf probe 0 60000000; " ，编译烧录进去，打印参数信息printenv，还是"sf probe 0 50000000; " ，所以也就是说，不管怎么编译uboot，我添加进去的东西根本没有编译，原因是什么具体分析不出来。
