multilink universal not being recognized

haroldvogel — Tue, 22 Dec 2015 14:28:02 GMT

When I attempt to load the application on to my board in the debugger I receive:

I have unplugged and plugged in the USB connector to the multilink unit.

I have restarted the computer.

I have turned off the computer and restarted the computer.

I have powered off the board and disconnected the multilink unit powered the computer down and restarted the computer after the computer is up and running I connected the USB cable to the multilink device and powered the board back up with the same above result.

Hope you can tell me what is wrong.

Hi John,

It seems the interface is recognized as it's displayed in the P&E Connection Assistant.

Most of the time (from my experiences) I met similar problem when the connection on board was wrong (wrong port).

Now if there is a problem with the P&E driver, on the P&E web site you will find some information which could help you but for me it's not the problem.

Please have a look to:

P&E Microcomputer Systems

This morning I've performed some tests on my side.

The configuration used was:

- Multilink Universal rev.B

- TWR-K21D50M with TWR-ELEV

Test_1: Multilink plugged on PC -> not connected on board.

On Multilink only the led blue was lighted.

Here I got same message:

Test_2: Multilink plugged on PC -> connected to the board but board power off.

On Multilink only the led blue was lighted.

Launching the debug session, the same error appears.

Test_3: Multilink plugged on PC -> connected to the board and board power on.

On Multilink the leds blue and orange were lighted and the application is loaded on board.

For me you've a problem between the Multilink and board.

This could be due to wrong on-board port used or power supply.

Have a great day,
Pascal
