k3路由器spi下刷写疑惑求助,虚焊终结该帖

1 这是我的未刷写时的分区情况备份：
dev:    size   erasesize  name
mtd0: 00080000 00020000 "boot"
mtd1: 00100000 00020000 "nvram"
mtd2: 00100000 00020000 "nvram_back"
mtd3: 00040000 00020000 "res_info"
mtd4: 00020000 00020000 "pro_info"
mtd5: 00020000 00020000 "dev_info"
mtd6: 02c00000 00020000 "linux"
mtd7: 029e1d94 00020000 "rootfs"
mtd8: 05000000 00020000 "brcmnand"

写了SPI后启动：
Device eth0:  hwaddr FD-8C-0X-67-CA-0A, ipaddr 192.168.2.1, mask 255.255.255.0
        gateway not set, nameserver not set
open 'nflash1.pro_info' error
Invalid boot block on disk
!! Could not open boot device
flash0.0: Device not found
Loader:raw Filesys:raw Dev:flash0.os File: Optionsnull)
Loading: Image compressed with unsupported method
Failed.
Could not load flash0.os:: Unsupported function

这里常见的写入cfe的命令是：
flash -noheader 192.168.2.10:mtd0.img nflash0.brcmnand
结果是：
Reading 192.168.2.10:mtd0.img: Done. 524288 bytes read
Programming...Failed.: I/O error

我认为明显不对：写入分区应该是nflash0.boot
结果是:
flash -noheader 192.168.2.10:mtd0.bin nflash0.boot
Reading 192.168.2.10:mtd0.bin: Done. 524288 bytes read
Programming...done. 524288 bytes written

但是继续写固件还是上面的错误提示
而flash -noheader 192.168.2.10:mtd0.img nflash1.boot   
Reading 192.168.2.10:mtd0.img: Done. 524288 bytes read
Programming...done. 524288 bytes written
这个正常

CFE> flash -noheader 192.168.2.10:mtd0.img nflash2.boot  
Reading 192.168.2.10:mtd0.img: Done. 524288 bytes read
Programming...done. 524288 bytes written
CFE> flash -noheader 192.168.2.10:mtd0.img nflash3.boot
Reading 192.168.2.10:mtd0.img: Done. 524288 bytes read
Programming...done. 524288 bytes written

这是啥情况喃？  

2 请教如何看机器有几个可写固件的硬件喃？ 哪个是SPI 哪个又是NAND?  空间大小又如何查看 ？其分区又如何查看喃？  
3 再请教如何重写整个分区表？  而不是完整的分区

自顶：1是硬件没焊接好 未找到NAND nflash0是NAND  终结该帖
