OpenSDA Firmware for TWR-K65

[peterruesch]

Hi,

while I was trying to get the TWR-K65 running, i reflashed the on-board OpenSDA-Debugger with some firmware which is not functioning.

The Processor is not powered any more.

Ofcourse I tryed to fix the problem by flashing the approriate firmware back to the OpenSDA, but unfortunately, the available TWR-K65 firmware from the "OpenSDA Firmware (MSD & Debug)"

package does not fit into the Mass Storage Device the OpenSDA presents in the bootloader mode

could someone please give me an advice on how to get the correct firmware onto the OpenSDA debugger on the TWR-K65 module ?

best regards

Hello Peter:

What is the status of this issue?

If you still have the problem please try to load the attached J-link binary to your TWR-K65 in BOOTLOADER mode.

- Press and hold RESET button (SW1).

- Connect the mini-USB port (J7)  to give power to the board. It should enumerate as a BOOTLOADER volume.

- Drag and drop the attached J-Link binary.

- Disconnect and connect the USB cable.

- Now it should enumerate as J-Link debug interface. Try to connect with KDS using the Segger connection.

If this does not work, please check the issues mentioned by colleague Erich Styger in his blog:
