TWR-K60N512 reset problem prevents reprogramming

flav1 — Mon, 09 Feb 2015 19:05:38 GMT

Hi!

I'm working with the TWR-K60N512 board and I wanted to configure the FLL. But now, when I'm resetting the microcontroller, the reset pin stay to the low level (I measured it), and it's impossible to reprogram it with the OSJTAG. I think it's because of an anormal comportment of the microcontroller which prevent its communication with the embedded OSBDM. The only way to have the microcontroller working is to disconnect and reconnect the board.

I want to know if there is a way to erase all the internal flash thanks to the OSJTAG or the jumper configuration to remove this comportment and to let me reprogram the component.

Best regards,

Flavien

Hello flav1:

There are ways to perform a mass erase. The procedure depends however in your IDE or available tools.

Please provide more details about what software you are using (e.g. CodeWarrior, IAR, Keil).

Hi Flavien

Try with CodeWarrior with the Hardware Connection properties set to perform an erase on connection:

This can be used to erase when SW behavior is otherwise immediately causing the debugger difficuties.
