However, even without a license, you can use J-Flash to create a bin from hex/mot to bin. And of course there are lots of other tools for hex/mot/bin conversion. Anyway, there is also a little tool called 'J-FLash Lite' in the default software package that let's you reprogram through a minimalist GUI without a J-Flash license if that's what you. Flasher PRO from SEGGER is a programming tool for microcontrollers with on-chip or external Flash memory and ARM, RX or PPC core. Flasher PRO is designed for programming flash targets with the J-Flash software or stand-alone. In addition to that Flasher PRO has all of the J-Link functionality.

The J-Link software comes with an additional feature, called Unlimited Flash Breakpoints. Unlimited Flash Breakpoints allow the user to set an unlimited number of breakpoints when debugging in flash memory.
The J-Link software comes with an additional feature, called Unlimited Flash Breakpoints. Unlimited Flash Breakpoints allow the user to set an unlimited number of breakpoints when debugging in flash memory. Without this feature, the number of breakpoints which can be set in flash is limited to the number of hardware breakpoints supported by the debug unit of the CPU (2 on ARM 7/9, 4-6 on Cortex-M).
J-Link's 'Unlimited flash breakpoints' works in both internal and external flash, even memory mapped QSPI flashes! J-Link has a smart strategy of using hardware breakpoints as much as possible, but once the CPU runs out of hardware breakpoints, J-Link automatically uses Flash breakpoints.1
J-Link's 'Unlimited flash breakpoints' actually work even in situations where hardware breakpoints can not be used, such as external memory or memory mapped QSPI flashes that are outside of the area on which hardware breakpoints can be set. On most Cortex-M3 and M4 devices, hardware breakpoints can not be used on external memory, 'J-Link's Unlimited flash breakpoints' can.

SEGGER J-Link Flash Breakpoint Introduction
There are basically 2 types of breakpoints in a computer system: Hardware breakpoints and software breakpoints. Hardware breakpoints require a dedicated hardware unit for every breakpoint. In other words, the hardware dictates how many hardware breakpoints can be set simultaneously. ARM7, ARM9, and some devices implemented with the Cortex-M0+ cores have 2 breakpoint units (called 'watchpoint units' in ARM's documentation), allowing 2 hardware breakpoints to be set. Hardware breakpoints do not require modification of the program code. Software breakpoints are different: The debugger modifies the program and replaces the breakpointed instruction with a special value. Additional software breakpoints do not require additional hardware units in the processor, since instructions are replaced inside the code to indicate the breakpoint. This is a standard procedure that most debuggers are capable of, however, it requires the program to be located in RAM.
Can I Use Unlimited Flash Breakpoints in CFI NOR Flash?
A: Yes! On some CPUs it is the only way to set breakpoints in external flash memory. For example, in Cortex-M systems, the typical 6 hardware breakpoints of the Flash-Patch Unit can NOT be used to set breakpoints in external memory on most Cortex-M system, since the address range of the unit is limited. This means: If you are using a Cortex-M3 or M4 with external flash, a program in this external flash can not be debugged with the popular emulators except a J-Link with the 'Unlimited Flash Breakpoint' license. In other words: When debugging a program in external flash on a Cortex-M device, a J-Link with the 'Unlimited Flash Breakpoint' license such as J-Link ULTRA+ is almost a must.
A: Unlimited Flash Breakpoints allow you to set an unlimited number of breakpoints even if your application program is not located in RAM, but in flash memory. This is a scenario which was very rare before ARM-microcontrollers hit the market. This new technology makes very powerful, yet inexpensive ARM microcontrollers available for systems, which required external RAM before. The downside of this new technology is that it is not possible to debug larger programs on these micros in RAM, since the RAM is not big enough to hold program and data (typically, these chips contain about 4 times as much flash as RAM), and therefore with standard debuggers, only 2 breakpoints can be set. The 2 breakpoint limit makes debugging very tough; a lot of times the debugger requires 2 breakpoints to simply step over a line of code. With software breakpoints in flash, this limitation is gone.
How Does this Work?
A: Basically very simple:
The J-Link software reprograms a sector of the flash to set or clear a breakpoint.
A: A RAM Code, specially designed for this purpose, sets and clears Flash Breakpoints extremely fast; on micros with fast flash the difference between breakpoints in RAM and flash is hardly noticeable.
How is This Performance Achieved?
A: We have put a lot of effort in making Unlimited Flash Breakpoints really usable and convenient. Flash sectors are programmed only when necessary; this is usually the moment that the execution of the target program is started. A lot of times more than one breakpoint is located in the same flash sector, which allows programming multiple breakpoints by programming just a single sector. The contents of program memory are cached, avoiding time consuming reading of the flash sectors. A smart combination of software and hardware breakpoints allows us to use hardware breakpoints a lot of times, especially when the debugger is source level-stepping, avoiding reprogramming flash in these situations. A built-in instruction set simulator further reduces the number of flash operations which need to be performed. This minimizes delays for the user, maximizing the life time of the flash. All resources of the ARM micro are available to the application program, no memory is lost for debugging. All of the optimizations described above can be disabled.
A: The software is licensed on a per J-Link basis. It requires a J-Link with Flash Breakpoints. J-Link Flash Breakpoints can also be used with J-Link ARM RDI / RDDI and J-Link GDB Server. If you want to use Flash Breakpoints with J-Link ARM RDI / RDDI, you will need an additional license for this software component too.

Can I use Unlimited Flash Breakpoints with Different Software Components
A: Unlimited Flash Breakpoints can be used with the following J-Link software components:
- J-Link DLL (For example if you use the J-Link DLL natively in IAR Embedded Workbench for ARM or RealView® MDK)
- J-Link ARM RDI / RDDI
For more information about how to use Flash Breakpoints with the different software components, please refer to the corresponding manuals.

SEGGER Microcontroller today announced the free availability of the flash download option for J-Link. The feature is free with J-Link software version 4.08l, available now. Yct games free download for windows 7. The flash download option is a collection of optimized flash loaders allowing the user to easily and very quickly download into flash of the supported microcontroller directly from the debugger in the same way as downloading to RAM. Taking full advantage of J-Link's high download speeds up to 720kB/s into RAM, it allows programming the flash of most common microcontroller very quickly.
The other way is that you add a button to the reset pin and pull it to GND. Give it a try. Dear Erich, regarding your post I'm having a similar problem with internal KE02 EEPROM.
Using universal multilink i had no way to unlock it,and the odd thing is that one of the devices was new,so i was not able to flash it for the very first time.The project that i tred to load was working fine with other boards let's call it 'A_project'. I built an almost empty project,let's call it 'Dummy' and i have found a difference in Hex files: In A_project the byte ad address 0x40C=0x7E and in 'Dummy' 0x40C=0xFE.,at least the SEC bits were Unsecured,i will check why i haveKEYEN Field= Backdoor key access disabled Furthermore the reset pin toggles continously(it has 10K to VDD,100nF to GND). I dont ‘have a Segger J-Link,but almost for shure i should have some demo board with a J_Link on board.

Unlocking and Erasing with J-Link Commander Summary In order to re-program the protected FLASH sectors with Segger J-Link, I need first to unlock and mass erase the device.
For this, there is the J-Link Commander utility which has a command line interface to unprotect and erase the device. For erasing only, the J-Flash (and Lite) is a very useful tool, especially to get a ‘clean' device memory. To me, the Segger way and tools are very powerful. In this case, things are very flexible, but not that obvious. So I hope this post can help others to get his device unlocked and erased. Happy Erasing 🙂.
The advantage of that is first speed. And it does not erase the application data I'm using in non-volatile memory (see ''). However, sometimes I really need to clear all my data in FLASH too, and then I need to erase all my FLASH pages on the device. Segger has product named ‘J-Flash' which is used to Flash and Erase devices outside of an IDE. There is a free-of-charge ‘Lite' version available for download from Segger. This utility is not intended to be used for production.

SEGGER also provides a RAMCode template which enables customers to write a custom RAMCode on their own. The RAMCode template is available.
For example, if you want to use the internal flash of your target hardware as well as the external flash for the target application code, multi-bank programming enables you to download the target application into the internal and external flash in one flash programming session. The settings for both flash banks are saved in the same J-Flash project, so you will only need one project in order to program multiple flash banks. Since the connection of these flashes varies from microcontroller to microcontroller, there are always some modifications which are necessary, to get DataFlash/NAND/SPI-NOR flash supported on a specific hardware.

The reason why you see the reset pin toggling is that the device is continuously resetting: it starts, then runs into a hard fault, restarts again, etc. You might try as well to pull down (e.g. Push button) the reset line while you connect to the target. This would give the debug probe a chance or larger time window to connect to the microcontroller and halt it. You migt try this several times. I hope this helps, and good luck!

H-JTAG.dll in approprite folder. With a cheap Olimex Wiggler it could work like a true debugger(tracing, stepping and so on). But watch out, unless You're a pro, practice a lot. I actually used the H-JTAG v. 9 and - beside that Segger couldn't either download or debug my code- I was able to download my code via the RS232 interface and later correct the code until it was errorfree and, again download the correct code. Don't fret, there's always a workaround cheap JTAG stuff Godd luck « Last Edit: July 02, 2009, 08:44:04 08:44 by robban » Logged.
So if you are using JTAG, you should be able to connect. If you only have SWD, then you need to be able to connect with the debugger during this tiny window. So I would try to debug it while the microcontroller is powered up. You might need 10, 50, 100 or more tries, but I think this is what you can do.

No, there is no utility for this as far as I know. So in your case the reset pin is still active after power-up until it reads the FOPT register. With JTAG you can reset the device using the JTAG command.
