To access a list of supported devices, please go to supported CPUs and devices.

If a device is not yet listed there, silicon vendors and end customers can add support for said device by themselves using the Open Flashloader feature.

On supported CPUs, all kinds of flashes can be programmed J-Link is Fastest in Flash Programming Speed Comparison The industry leading J-Link has been subjected to a flash programming speed comparison against various debug probes.

The flash download performance with J-Link has been tested with various devices.

These tests were performed with J-Link Commander by placing an image of the full flash size of the device into the flash memory of the device.

Precondition: flash was empty or erased, as the flash erase times depend very much on the selected device.

Please refer to the chip manual of the appropriate device to get information about erase times.

While in the beginning, SPI NOR flash was usually a custom connection and not standardized, with advanced MCUs and making the QSPI flash memory-mapped visible in the MCU address space, it became a full replacement and even successor of parallel NOR flash.

With J-Link, all features known from internal flash are also available in memory-mapped QSPI flash: Make flash behave like RAM in the debugger (e.g.

Flash breakpoints (unlimited number of breakpoints when debugging in flash) Any IDE (e.g.

GDB based ones) can easily download to flash without even the need to add some sort of custom flash algo in the IDE, as J-Link does all the work Note: On many Cortex-M based devices, hardware breakpoints are not usable in QSPI flash, making J-Link flash breakpoints the only real option to debug in QSPI flash on these devices.

Parallel CFI NOR flash support The flash download feature of J-Link supports programming of external CFI-compliant, parallel NOR flash devices, allowing these devices to be programmed either directly from the debugger or through J-Link commander.

For more information regarding how to setup the debugger J-Link Commander for download into parallel (CFI) NOR flash memory, please refer to UM08001, chapter Flash Download.

For production environments, we recommend using J-Flash or Flasher ARM standalone.

Non-Memory Mapped Flashes: Serial NOR-, NAND-, DataFlash and EEPROM Since these flash devices are not connected to the address and data bus directly and the connection to the CPU MCU MPU differs from device to device, a customized flash algorithm is necessary in order to program these flash devices.

This can either be done by the customer or by SEGGER (request quote: salessegger.com ).

With custom algorithms it is possible to program these types of flash devices via J-Flash and Flasher ARM.

To program SPI flash memories directly via the SPI bus, there is J-Flash SPI.

Still there are occasions, where support for a device is needed, that is not available yet.

In such cases the Open Flashloader feature allows to add support to the J-Link.

The device will be supported in similar fashion as all the devices supported already.

This includes flash download as well as the unlimited flash breakpoint feature.

In addition to creating support for the device, an existing CMSIS compatible flash algorithm can be used to create support for the J-Link as well.
