I am developing a control firmware for a costumer device, based on ADuC834. I would like to provide end users a mean to update firmware on site, but I would prefer to avoid developing my own bootloader and associated windows application. So my idea was to reuse embedded Serial Download mode.
But I need a way to enter Serial Download mode while being inside the application.
So here is my question: how to initiate Serial Download mode from user code? Preferably without having to reset the chip?
Thank you for your help
