The manual says that if p0.14 is low while reset is low, forces on-chip boot-loader to take over control of the part after reset. However, when I connect this pin to ground, while the user code is executing (Blinky), the program stops! When I connect it to the 3.3V pin on the motherboard, Blinky starts running again! And all this time reset is never low. Is this supposed to happen? It doesn't seem so according to the flowchart in the manual.
Hi Per,
I am re-reading your post. So, you mean the DB9 male connector could be for another device which is not a PC?

If this is the case, then it is a mismatch with the example project and the schematics.
But yes, The most common application for the S2E module is for augmenting legacy products that contain a serial port for a configuration or control interface. Simply installing a S2E module into the legacy serial device provides instant networking capability with no major board redesign or software changes, a tiny form-factor for unobtrusive implementation, and cable lengths much longer than what is available for simple serial connections.
