Solved: Is there a way to erase flash memory on D2000 after flashing "power" example from qmsi-master?

idata · ‎03-15-2016

I imported the power example program from qmsi-master and ran it.

I receive terminal outputs:

"Low power mode example.

CPU Halt.

CPU Halt wakeup.

Go to sleep.

Wake up from sleep.

Go to deep sleep."

I am unable to exit from deep sleep though using the comparator pin 6 and I am also unable to load other programs because I think OpenOCD is unable to communicate with the D2000 due to it being in deep sleep mode.

How can I resolve this?

Can I erase the flash program memory without using OpenOCD?

I tried updating the target ROM but received the following popup window:

"

Could not update the ROM. Setup target failed.

Hi ,

If you are using the 'power' example provided without any changes you should be able to wake from deep sleep by connecting Pin 6 - this is marked as Analog Pin5 (A5) on the CRB - to GND.

Make sure this is connected before you reset the board. When the serial output shows 'Go to deep sleep' unground the pin and you should see it wake up.

Low power mode example.

CPU Halt.

CPU Halt wakeup.

Go to sleep.

Wake up from sleep.

Go to deep sleep.

Wake up from deep sleep.

However if this does not work you can recover the board by Grounding Digital Pin 0 and re-flashing the ROM (this process should work in most cases where you loose JTAG access)

- Connect a jumper wire from Digital Pin 0 to GND

- Reset the board (Power off/on)

- From the ISSM menu select 'Update Target ROM'

regards,

Michelle.

Hi Michelle!

Thanks for the help knowing how to use the power example! It worked and it's also really nice to know how to update ROM if I ever get into a bind again.

Best regards,
