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.
• For Manufacturing (Blank Flash Memory)
 IAP (In-Application (re)-Programming)
• Applicable to programmable logic and Non-Volatile Memory (NVM).
• MCU is on-line and participates in programming the memory.
• For Field Updates (Firmware upgrade)
The term In-System Programming (ISP) is used in a general sense by the
industry.

Flash Programming Terms and Definitions
 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.
 Automated/Gang Programming Systems:
• Same as above but for mid-volume to High-volume programming.
• Up to 5000 devices per hour

Debug Phase – Development Tools
Most of today’s Development Tools like, IAR, KEIL and others,
integrate their own Flash Programming Tools.
The Flash Tool is started like any other function by one
“Download and Run” Button.
This is the simplest way to flash your application
during debug phase !
Advantages:
 Fast Programming
 All AT91SAM7 MCU supported.
 Updates maintained via patches from Tool Vendors.

Debug Phase - SAM-BA
TM
SAM-BA allows on-board memory programming through USB,
DBGU (UART) or JTAG.

SAM-BA may be needed:
 In case of JTAG/ICE connection problems
 If no ICE interface is available for debug
 as a Demo Downloader
* For Customer Boards Design, See SAM-BA Hardware Constraints in the corresponding
product datasheet

10
Debug Phase – Customizing SAM-BA
TM
 Customizing SAM-BA is possible by adding or modifying
TCL scripts files.
 Command Line Mode: allows memory programming without any
GUI interaction
Example: sam-ba.exe \usb\ARM0 programSAM7.tcl

Debug Phase - SAM-PROG
SAM-PROG allows flash programming through USB or JTAG.
Major Features:
1
 File selector or Drag-n-Drop,

2
 I/O pin selection for user feedback
after programming
2
 User Feedback and Status
• Flash Programming Report,
• Number of connected boards
 Auto Mode for Drag-n-Program

AT91-ISP:
Build your own Flash Programming GUI
Provides an open set of tools for programming the AT91SAM7
and AT91SAM9 ARM®-based microcontrollers.
The AT91ISP solution is not only based on 2 applications
(SAM-BA and SAM-PROG):
 AT91Boot_DLL.dll
SAM-BA
 SAM-PROG
 TCL script and Visual C++ projects examples
 Command line application using a TCL shell (AT91Boot_TCL.dll)
 SAM-BA Boot4CAN binaries (SAM7A3 and SAM7X)

Introduction
How to choose between Manual and Automated
Programming?
(Data I/O Source)
by calculating the total cost of programming...
by adding the cost of:
 direct labor,
 direct materials,
 scrap/repair materials,
 capital expense equipment,
 indirect labor costs for automated programming versus manual
programming,
…and comparing the two scenarios.

Small Production Flash Programming
(Manual Programming)
 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 Parallel Mode of Fast Flash
Programming Interface (FFPI).
See Appendix A for Programming Vendor Tools vs. Supported Devices

17
Medium & High Production Flash Programming
(Automated)
When Medium and High Volume (1000 dev/hr) Flash Programming is
required, the cost efficient solution is to use Automated Programming
Methods.
Automated Programming can be split into two categories:
1) On-Board Flash Programming:
Automated Test Equipment
2) Off-Board Flash Programming:
 Automated High-Volume Gang Programmer
(BPMicro 4710)

Medium & High Production Flash Programming
(Automated)
On-Board Programming
On-board Programming can be achieved via the Fast Flash
Programming Interface (FFPI)*.
FFPI Serial Access via the JTAG/ICE Port (5 pins).
 Small and High Density PCB (ex. Mobile Phone) where PCB
access points for bed-of-nails test equipments is not possible.
• FFPI Parallel Access via dedicated PIO pins (8 to 16 bit data bus + 11
control pins)
 PCB access points for bed-of-nails test equipments is possible,
 On-board FGPA for programming the AT91
* For Customer Boards Design, See FFPI Hardware Constraints in the corresponding product
datasheet

19
Medium & High Production Flash Programming
(Automated)
Off-Board Programming
Off-board Programming is done on Automated High-Volume Gang
Programmers like the BPMicro 4710 Programming Station.
The BPMicro 4710 can handle up to 1200 devices per hour.
All programming tool vendors use the Parallel Mode of the Fast Flash
Programming Interface (FFPI).
Some distributors have programming centers equipped with
Concurrent and Automated
High-volume Gang Programmers and offer programming
solutions to customers for little extra fees per devices
programmed.
