The NXP QN9090 / QN9030 are ultra-low power, Cortex-M4 based wireless microcontroller supporting Bluetooth Low Energy 5.0.

Internal Flash

Supported Regions

The internal flash is divided into 3 different regions:

  • Reserved by flash controller (0x9F000 - 0x9FFFF)
  • Reserved by boot code (0x9DE00 - 0x9EFFF)
  • Application space (0x00000 - 0x9DDFF for JN5189; 0x00000 - 0x50000 for JN5188)

For now, the J-Link supports the application space, only.

Vector Table Remap

The first 512 bytes of the device (0x0000 - 0x01FF) can be mapped to flash, ROM or RAM. When using the J-Link flashloader, this region is mapped to flash. This is done on purpose as the device does not provide a mirror address for the first 512 bytes of flash.
