SAM7-P256 issues

Dear,

recently I bought this board in Amazon.
My first project was to flash a blinking demo (SAM7_Pxxx_led.bin) from this site using J-Link.
It went Ok but I have issues with the reset. It takes couple of times to plug in and out
the debugger to let it blink. If I connect a PSU (6VDC) or USB cable it does not blink anymore after I hit the reset button.
Is this a known hardware issue of the board is simply defect? Thanks in advance.

Which memory did you use to download the example? If it is in the RAM it might disappear after reset?

Are you sure that the software is not keeping the board in reset via the J-Link?

Of course, there is always a chance there is a bug in the demo example or the binary...
