The NXP NxH2004 are ultra-low power, Cortex-M0+ based wireless microcontrollers supporting Bluetooth Low Energy. This article covers the NXP (Cortex-M0+ dual-core).
Internal Flash
Supported Regions
The internal flash is divided into 2 different regions:
- Reserved by NXP region (0x9EC00 - 0x9FFFF)
- Application space (0x00000 - 0x9EBFF)
For now, the J-Link supports the application space, only.
ECC flash
The flash seems to be ECC protected. Read fails for sectors with invalid ECC (e.g. erased sectors). In order to prevent errors when reading empty sectors, the DLL do neither perform a blank check nor a compare of the flash content before programming.
Reset
The NXP NxH2004 devices require a special reset handling because some registers are not reset to their reset values correctly, due to a silicon bug. This is done by J-Link automatically.
