Hi guys,
I am a totally newbie with QSB, when I plugin the power, the FLT and 5V led light on. While I plugin the UART with my computer, seems computer cannot distinguish any new port. At the same time, when I press poweron button, the LCD has no display. Anything wrong with the board? Months before, it can start correctly. What happen? How can I diagnose? Thanks.
Thanks for ur reply, I'v used the original power adapter, I think it's ok. I doubt if it's the os issue or the board is broken. While I cannot get log from serial port, I totally don't know how to begin. Is there any way I can be sure the board is ok? Any way to access the "BIOS" like PC or something like that?
Hi Yuri Muhin, After pressing power on, only the FLT and 5v led of the QSB shine, just as when plugin the power. And u said "If not - problems with power.", I thought that means the adapter is broken, after I bought the new one, the problem is same. And I can hear the board make a sound "zizi sisi" all the time. Any idea? How can I find the problem? Really thanks.
Oops, I am not sure. Where is the chip, and how can I check it? I don't know the hardware at all. I am reaally confused with the integrated board.:smileyconfused:
