QSPI Flash
QSPI flash programming requires special handling compared to internal flash. For more information about this, please see the QSPI Flash Programming Support article.
J-Link supports multiple pin configurations for [DEVICE]. The default loader is marked in bold.

Multi-Core Support [OPTIONAL]
Flash programming is done by KM0 core (Cortex-M23).
The [DeviceFamily]family comes with a variety of multi-core options.
Some devices from this family feature a secondary core which is disabled after reset / by default.
Some of the are available with enabled lockstep mode, only.
In below, the debug related multi-core behavior of the J-Link is described for each core:
Main core
Init/Setup
- Initializes the ECC RAM, see XXX
- Enables debugging
Reset
- Device specific reset is performed, see XXX
Attach
- Attach is not supported because the J-Link initializes certain RAM regions by default
Secondary core(s)
Init/Setup
- If the main core session has not been started / debugging is not enabled yet, the secondary core executes the enable debug sequence.
- If the secondary core is not enabled yet, it will be enabled / release from reset
Reset
No reset is performed.
Attach
- Attach is supported / desired
Device Specific Handling
Reset
- The devices uses normal Cortex-M reset, no special handling necessary, like described here.
Limitations
Dual Core Support
Some XXX devices feature a second core. Right now, the J-Link software does support the main core, only. Support for the second core is planned for future versions.
