While sysupgrading something went wrong and my Buffalo WZR-HP-G300NH stuck during boot.
Then I tried to connect via serial port.
First tried the RS232 interface and then a serial-USB adaptor.
In both case, what I read from serial port when I plug the adaptor in is something like this:
xaa:\0xfa+\0xaa*
\0xda\0xd4\0xb4\0xec\0xeb\0xd66\0x96\0xe9\0x9b\0xdaT\0xaa\0xba*\0xeb\0x00R\0xfb\0xfb\0xfb\0xdb6\0xdb\0xf6\0xf6\0xf6\0xf6\0xf6V\0xeaK\0xd5\0xda\0x1a\0xaa:\0xfa\0xfb\0xd4\0x1aj\0xca\0xfa+\0xfb\0x1b

\0xda\0xf4\0x8b\0xaa\0xd4\0xba\0xea\0x1a\0xca\0xaa\0x1a+\0xeb\0x00
Serial terminal settings are correct and I used the same settings before. (115200,8,N,1)
Also tried other baud rates just in case, but no luck.
Something wrong with bootloader?
Thanks in advance.
