C51: BOOTLOADER AND ISP FOR THE CYGNAL C8051FXX DEVICES

Information in this article applies to:

• C51 All Versions

QUESTION

I am using a Cygnal C8051F010 chip and want to write a bootloader that provides In-System Reprogrammibility (ISP) of program memory either upon reset or upon reception of a reflash command. I know that I must use the JTAG for the initial virgin chip download of my program code with the ISP included. What sources of information are available for writing the ISP code with the Keil C compiler?

ANSWER

The Cygnal web site contains AN012 - C8051F0XX Bootloader Considerations and Example and associated software for Keil uV C51 v6.10.

Check the Cygnal Web Site for AN012 - C8051F0XX Bootloader Considerations and Example.
