TWR=MCF51CN Bootloader Mode problem

[pawelniewiadoms]

Hello,

I have TWR-MCF51CN board and I have problem with bootloader mode in it. When I want to update my firmware by P&E firmware updater I have to use jumper on J16. When I've done it my device become undetected. When I use CodeWarrior v10.6.4 it also makes update of my firmware and it's the same problem. It happens when I reconnect my board with jumper on. Without jumper on J16 my device is detected. I'm using Mini USB cable as debugger.

Thanks for all responses.

Greetings,

Pawel.

Hi Pawel

The J16 is only use if you want to update the firmware on the JM60 (OSBDM), if this is present you only can update the firmware with the P&E tools.

If you want to program the MCF51CN you need to remove the J16.
