GENERAL: GETTING PROGRAMS ONTO A TARGET BOARD

Information in this article applies to:

• MCB167-NET Evaluation Board
• MCB251 Evaluation Board
• MCB520 Evaluation Board

QUESTION

How can I take a program I have written and store it on an evaluation board so that it starts running every time I power-up the board?

ANSWER

To have the same program start each time you power-up a target board, you must store that program in some form of permanent memory. The memory must retain the program even without power present.

Embedded programs are usually stored in ROM, EPROM, EEPROM, or FLASH memory. The application program is burned into a ROM using a device programmer. There are several links to good device programmers on the Keil web site at http://www.keil.com/links/deviceprog.htm.

In addition to programming EPROM, EEPROM, and FLASH memory, many device programmers also allow you to program various microcontrollers that offer on-chip FLASH or ROM.
