Am using SAM E70 XPLAINED dev board.
Am currently working on lwIP web server implementation.

Everything seemed to work great till last day.
Today, when I powered on the board, my PC failed to detect the board.
It is not getting detected in device manager as well.

 

When I shorted the erase jumper(J200), surprisingly, the board got detected. But sadly, it was detected as "Bossa Program Port". I can't program the board as well.

What am I supposed to do?

I haven't done anything to the bootloader.

 

How can I get the board back working?

 

I really need some help.

Hi,

 

Are you using Atmel Studio or something else?

 

Are you 100% sure you are using the same USB port?

 

For normal programming you should use the connector marked DEBUG, not TARGET. **check this **.

 

The DEBUG connector connects to the embedded programmer on-board, which is normally what you want.

 

The TARGET connector connects to the SAME70 chip. You should only be able to 'talk' SAM-BA there. SAM-BA is the protocol used bij the BOSSA program.

 

To verify, connect a serial terminal program to the port at 115200 baud, 8 data bits, 1 stop bit, no parity (8N1). Type the two characters 'V#'. If you get a human-readable reply with a version number,  you are indeed talking to a SAM-BA port.

Hi,
Thank you for the reply.

Am using atmel studio 7.

I have connected to debug port.

I have been using this board for over a month & this is the first time am seeing something like this.

Strange, but the board seems to work now.

I really don't know what happened.
Now it is working fine.

It is getting detected as virtual comm port.

Wondering what is happening with the board!!!

Thank you guys for the support.
