Flash Programming Terms and Definitions

• ISP vs. IAP
• ISP (In-System Programming)
• Applicable to programmable logic and
  Non-Volatile Memory (NVM).
• MCU is off-line and/or not involved while memory
  is being programmed.
• Well suited for Manufacturing.
• IAP (In-Application (re)-Programming)
• Applicable to programmable logic and
  Non-Volatile Memory (NVM).
• MCU is on-line and participates in programming
  the memory.
• Well suited for Field Updates.
• The term In-System Programming (ISP) is used in a
  general sense by the industry.

With ATMEL Evaluation Boards or Customer Board
Debug Phase

• In this case, the Flash Downloader software is
  compiled with the Development Tool and downloaded
  into the internal or the external SRAM through
  the ICE like any other Applications. Then the
  Flash Downloader runs from SRAM and programs the
  Flash Memory from a file stored on the computer
  (thanks to the semihosting feature of the Dev.
  tool).
• Advantages
• Fast Programming. The Processor is running at
  Full Speed !
• Only way to recover the on-board software when
  the Flash is Blank.
• Usable for low volume programming by using
  script
• Easy Upgrade of the Flash Memory Architecture.
  Only change the Flash routines in your
  source code.
• Source Code Provided for Free from ATMEL on AT91
  CDROM ATMELs Website.
• Inconvenient
• Not usable for Several Programming Stations due
  to High Cost of Dev. Tool.
• This means that is not dedicated to Production
  Programming.

Debug Phase

• Most of todays Development Tools like Multi2K
  from GHS, IAR, ARM ADS and others, integrate
  their own Flash Programming Tools. This is
  similar to the ATMELs Flash Downloader but
  hidden for the user. The Flash Tool is started
  like any other function by one click.
• Advantages
• Fast Programming. The Processor is running at
  Full Speed !
• Only way to recover the on-board software when
  the Flash is Blank.
• Several Flash Memory Vendors are supported and
  list maintained.
• Inconvenient
• Some Flash Tools require a big amount of
  external SRAM to run.

• Macraigor Corp. provides a Flash Memory
  Programmer called OCDemon Flash Memory
  Programmer. It works with the Raven, Wiggler and
  MPDemon ICE interfaces from Macraigor. It
  supports all the AT91 Products, including the RAM
  version Only. Most popular Flash Memory Vendors
  supported. The Programming Sequence can be
  automated and is fully configurable.
• Advantages
• Supports All AT91 MCUs.
• All Popular Flash Memories Supported

With ATMEL Evaluation Boards Only Debug Phase

• The Flash Memory Uploader (FMU) is embedded in
  the Evaluation Board. This a part of the boot
  code. It allows the user to download his own
  application code into the upper part of the Flash
  Memory dedicated for that. As the FMU is running
  from the lower part of the flash, only the upper
  part of the Flash Memory can be downloaded. Two
  Host PC Softwares are available for free
• The AT91 Loader (Automatic Mode and Manual Mode)
• The EBload Tool from RTJ Computing (Manual Mode
  Only but more Friendly GUI)
• (Software Available from the ATMEL Web Site)
• Advantages
• Fast Programming. The Processor is running at
  Full Speed !
• Easy Upgrade of the Flash Memory Architecture.
  Only change the Flash Sector Size Definition in
  the configuration file (AT91Loader) or Settings
  in EBload Tool.
• AT91Loader Host PC Source Code Provided for
  Free.
• Inconvenient
• Not usable with an empty Flash Memory.

Uploader

• All Flash-based AT91 devices are delivered with
  pre-programmed software called the
• AT91 Flash Uploader, which resides in the first
  sector of the embedded Flash. The
• Flash Uploader (FMU) allows programming to the
  embedded flash through a serial port. Either of
  the on-chip USARTs can be used by the Flash
  Uploader.
• Advantages
• Supports All AT91Fx40 Series and Future.
• Automated thanks to Automatic Start Up when the
  target is connected to the PC.

JTAG/ICE Flash Programmer -

• The AT91EB40A JTAG/ICE Flash Programmer has been
  developed to allow easy Board Programming for
  AT91Fx40 Series and also for any Flash Memory
  connected to the External Bus Interface (EBI).
  Any AT91EB40A Board can be used with the Flash
  Programmer Software Stored in the Flash Memory.
• The aim of the application is to drive the
  JTAG/ICE port of the board to be programmed.
• See the App. Note DOC2668.PDF (
  http//www.atmel.com/dyn/resources/prod_documents/
  doc2668.pdf )
• and its associated software.

Small Production Flash Programming - Engineering
and Concurrent Programmers -

• Engineering Programmers
• Memory, PLD or MCU Programming Tool for Design
  Engineering.
• One device programmed at a time.
• Concurrent Programming Systems
• Same as above but low to mid-volume production.
• Up to 6 Devices programmed at the same time.
• All these Programming Systems use the tri-state
  mode of the AT91 to treat the AT91 like a
  Standard ATMEL Flash Memory.
• BPMicro Systems All the AT91Fx40 Series
• DATA I/O AT91FR4042 AT91FR40162

Medium and High Production Flash
Programming Concurrent and Automated/Gang
Programmers

• When Medium and High Volume Flash Programming is
  required (gt 1500/month) the only efficient
  solution is to use Concurrent and Automated/Gang
  Programmers available from well know names like
  BPMicro Systems, DATA I/O Corp. All these
  Programming Systems use the tri-state mode of the
  AT91 to treat the AT91 like a Standard ATMEL
  Flash Memory. Most efficient Programming Systems
  from BPMicro (BP3600) are able to program 700
  devices per hour.
• Some distributors have programming centers
  equipped with Concurrent and Automated/Gang
  Programmers and offer programming solutions to
  customers for little extra fees per devices
  programmed.
