RAM
In order to prevent errors when reading first time, the J-Link software intialises the first 4KB of RAM
starting at 0x20000000.
Due to this attaching to a running system is not possible.
Watchdog handling
- The device has a watchdog.
- The watchdog is fed during flash programming.
Device specific handling
Reset
- The device uses normal Cortex-M reset, no special handling necessary, like described here.
Attach
Attach is a debugging feature which exclusively applies to J-Link and J-Trace and does not apply to Flasher.
- Attach is not supported by default because the J-Link initializes certain RAM regions by default.
