Supported devices
Known devices are supported devices which are also known by name. Knowing not just the CPU core, but also the device by name brings the following advantages:
- Programming of internal flash (See Flash Download)
- Availability of unlimited number of breakpoints in flash memory (See Flash Breakpoints)
- Known memory map allows speed optimizations for access to Flash and RAM
- Support for non-standard CPU-cores & bugs in silicon: Some silicon requires special sequences for unlock, reset, or simply connecting to the core. For known devices, this is implemented
Please note: A device has not to be known by name to be supported. This means that J-Link can be used with any device, using a standard core listed in the table of supported CPU cores even if it is known by name.
List of known devices
The following list gives an overview about which devices are known by J-Link:
This list is always valid for the latest version (highest version number) of the J-Link Software and Documentation Package. This may be a release (even version number) or beta version (odd version number), since support for some devices is usually added in a beta phase first.
Device not listed? Please feel free to contact us.
Adding support for new devices
If a device is not listed in the list of known devices on this page, there are two options to get it to be known by J-Link:
- Adding support for it (incl. flash programming) on your own. For more information on how to do this, please refer to the SEGGER wiki.
- Get in touch with support@segger.com and issue a device support request.
Please note: A device has not to be known by name to be supported. This means that J-Link can be used with any device, using a standard core listed here, even if it is known by name.
Supported SPI flashes
J-Link does also support download into SPIFI (SPI Flash Interface) flashes in case they are memory mapped readable through the CPU (called SPIFI support on most targets). Moreover, utilities like J-Flash SPI also support direct programming of SPI flashes without any CPU in between. The following SPI flashes are currently supported by the J-Link software:
