新唐NUC972 norflash运行uboot nandflash运行linux 启动后固件丢失
想向大家请教以下几个问题：1、kernal启动起来之后，会对nandflash进行重新初始化，重新进行分区？
2、为何在uboot在内核启动时，对内核进行参数传递会无效？具体的内容请看后面的详细内容。
3、在linux内核驱动里面如何对nandflash进行分区，因为我感觉我传入的nandflash分区信息，内核并没有识别到，内核不知道怎么采用的默认的分区，这个默认设置地方我也没有找到（boot信息分区部分，可以看到原版固件里面的分区信息，和我自己编译后的分区信息并不一样）
以下是相关问题的具体描述
购买了NUC972 ARM9开发板，买来的时候忘记记录它自身的boot时所输出的信息了。目前根据文档里面的内容，烧写了文档里面的固件，将uboot和环境变量烧写到spi norflash里面，将uimage和rootfs烧写到nandflash里面。但kernal无法运行起来，输出的boot信息如下。

根据自己的理解，重新编译了uboot、uImage、和rootfs，重新对其进行烧录，可以进入到linux，但每次只能运行一次，再次上电后，uboot无法找到可以执行的image
Menuconfig和nandflash的配置如下
General setup--->
[] Initial RAM filesystem and RAM disk (initramfs/initrd) support
//这里由于要使用yaffs2文件系统，所以按照文档里的要求取消了ram filesystem
-*-Memory Technology Device(MTD) support--->
-*-NAND Device Suport --->
-*-Nuvoton NUC970 MTD NAND
NUC970 NAND Flash pin selection (Port C) --->
File System--->
[*] Miscellaneous filesystems--->
<*> yaffs2 file system support
-*- 512 byte/page devices
-*- 2048 byte(or larger)/page devices
[*] Disable yaffs2 background processing
[*] Enable yaffs2 xattr support
Boot Options--->
(noinitrd root=/dev/mtdblock1 console=ttys0,115200n8 rdinit=/sbin/init rootfstype=yaffs2 rootflags=inband-tags mem=64M)
Kernal command line type (Use bootloader kernel arguments if available) --->
烧写后第一次上电可以有正常的boot信息，也能进入kernel并运行相应的文件系统

此时将nandflash里面的前20个block里面的数据读出来，（因为1个block的大小为128K，20个的大小为2.5M，此空间大小大于uImage的大小了）发现数据全部都变成了0xFF。
该问题困扰了我2周了，也看了nuc972的相关论坛，那个论坛也是好久都没有人更新了，QQ也加了nuc972的群，也没有人通过，估计回家过年了，请有相关经验的大虾提携一下。
你先烧录新塘自带的制作好的系统试试看。 还有要通过跳线来选择烧录模式，你选择usb烧录后，按BSP手册上，把所有的东西都烧录到nandflash里面，然后从nand启动。 redworlf007 发表于 2019-1-29 12:12

烧录新塘自己的固件，通过SPI flash里面烧录uboot和环境变量，nandflash里面烧录kernel和rootfs文件系统，启动到了

此时 MTD partitions是按照uboot环境变量传入的内容，进行的分区；但内核启动后，重新断电仍然无法重新运行，感觉nandflash里面0--0x700000里面的内容全部被格式化了，目前还不知道是什么原因导致的
mount: mounting /dev/mtdblock0 on /mnt/mtdblock0 failed: No such device
mount: mounting /dev/mtdblock1 on /mnt/mtdblock1 failed: No such device
这个地方的failed，不明白是什么原因导致的 不对呀，你烧录新塘得固件，啥都不用自己改烧进去就好了，新塘的固件不是从nand驱动的，硬件选择从spi启动。 最近经过试验，找到了解决方法，现在还不知道这个方法是否正确，写出来，给大家做个参考。
在环境变量文件里面对mtdblock分区时取消了kernel的地址空间，原因我猜想是内核启动后由于一开始指定了对kernel地址空间部分进行分区，所以对其进行了挂载，在挂载后无法找到对应的文件系统，所以将其格式化了。 amxx 发表于 2019-2-13 13:51

在环境变量文件 ...
那个错误最后咋解决的？
