Flyport Wi-Fi and Ethernet Programmer's guide framework 2.3 (rev 1.0) www.openpicus.com

If the PC sends any instruction to write to a “dangerous” memory address, the bootloader stops

writing, avoiding “killing” itself. The IDE gives feedback to the user, saying “the code can damage the

bootloader, so it has not been written it”.

QUESTION: The bootloader is another program resident inside the microcontroller. Will it slow

down the micro? Will it reduce the available memory for the user firmware?

The bootloader runs for a short time only at the startup of the Flyport, so it doesn't slow the Flyport

down in any way. It uses just 1k of memory. So there is no real reduction of the available memory for

application.

NOTE: Flyport uses a customized version of the ds30 bootloader. An opensource and lightweight

bootloader for PIC microcontrollers http://mrmackey.no-ip.org/elektronik/ds30loader/
