Having a Problem with connecting to the TWRK65F180M mcu, and I definitely need help

When I plug in the board, the MCU does not turn on. Only when I press the reset button does the D3 LCD start blinking. my computer then recognizes it as a device, pulls up the BOOTLOADER drive, but I can only access it for about 10 seconds until the computer does not recognize it as a device anymore. The D3 LCD continues blinking even though the MCU is not recognized by the computer. Does anyone know how I can fix this?

Hi,

First of all, please refer TWR-K65F180M board user guide table 4 to set Jumper with default setting.

I would recommend customer to check here to updated the TWR-K65F180M board OpenSDA firmware.

Please select one firmware of the latest firmware application and copy to the Bootloader disk (press the reset button and then power the board at USB J7 port):

After that, power up the board again (release reset button), you could find related debugger was recognized at Computer device manager panel.

If there without any modification, I think the on board OpenSDA was damaged.

Customer could download the OpenSDA bootloader image and program the MK20 chip with related SWD interface (J5).

Wish it helps.


Have a great day,
