求助：TTL下命令的使用方法

785330264

路由器是台湾合勤科技的P-330W，RTL8186的方案，现在无法正常启动，TTL下正常加电有错误提示，按住reset加电反馈的信息如下：
UART1 output test ok
Uart init
mfid=000000c2 devid=00002249
Found 1 x 2M flash memory

---RealTek(RTL8186)at 2006.02.16-18:46+0800 version 1.4 [32bit](180MHz)
no sys signature at 00010000!

现想求助输入help以后出来的各项命令应该怎么用，或者说仅告诉我这里面哪一项有刷机功能，应该怎么用也可以，谢谢了！

flr flw猜猜可能是flash读写命令 可以用 flr /? flw /?看下帮助文件

就这样了，而且没法再换行了UART1 output test ok
Uart init
mfid=000000c2 devid=00002249
Found 1 x 2M flash memory

---RealTek(RTL8186)at 2006.02.16-18:46+0800 version 1.4 [32bit](180MHz)
no sys signature at 00010000!

---Escape booting by user
\>flr /?
Undefined Exception happen.

hackpascal

仅有flash读写命令(flw flr)而无文件传输命令，因此无法在此环境下刷入固件

另外，tashiyi01 说的方法导致系统故障了，需要重启
