On-Chip Memory Regions

The internal flash is divided into 5 different regions:

Instance Name Size (bytes) Memory region
Main Flash 393216 0x00100000 - 0x0015FFFF
Non-Volatile Record (NVR) 1 2048 0x00080000 - 0x000807FF
Non-Volatile Record (NVR) 2 2048 0x00080800 - 0x00080FFF
Non-Volatile Record (NVR) 3 2048 0x00081000 - 0x000807FF
Non-Volatile Record (NVR) 4
(Manufacturing Test)
1024 0x00081800 - 0x00080BFF

NOTE: J-Link supports the Main Flash as well as NVR1 - NVR3.


It seems like a normal reset via SYSRESETREQ & VECTRESET bit does not work properly on this device. Therefore, the J-Link software performs a specific reset which makes sure that CPU is halted right before the target application but after boot ROM.
