Hi everybody,

After receiving the board and installing the kit from Keil plus1 hour of struggling with set-up the board was ok :), ran some examples. Ok, excellent, reflashed the ST Link with the new firmware using the ST Link Utility (CRC passed) and started debugging a code of mine, again, no problems. The next day, I had an idea, started my laptop plugged the board and nothing :) I thought it's my mistake or the laptop had problems because it didn't detect the board....Restarted the laptop and the board also, again, nothing, the board wasn't detected by the OS. I tried the same procedure on 4 computers and none detected it....

So, the RED LED is blinking and the power led is on...

Any ideas ?

Thanks,

Mihai P

What OS was this tried on? What code was on board when you shut it down?

Fast response :) I was talking about the fact that Windows or any other PC can't recognize the board. When I say can't recognize I mean nothing appears in device manager also I don't get an error from Windows. Simply nothing happens the board isn't detected.....

Regards,

Windows or any other PC - also Windows I might assume? Might I assume Windows 7?

There could be a power problem but I would not know where to search for logs (dmesg) in Windows for that matter...

quoting clive1 from another thread: ''If your code is causing a problem pulling BOOT0 High at start up will remove it from being an issue.''

Have you tried this?

Hi,

 Thanks for the info, looks like the st link is fried. Don't know how I did it but this is my problem. Order 2 new boads from Farnell just for redunfancy.

Have a nice day,

Mihai P
