S32K14x series
The NXP S32K14x series is a scalable family of 32-bit ARM Cortex-M4 based MCUs targeted for general purpose automotive and high-reliability industrial applications.
Requirements
There are some special requirements that need to be fulfilled in order to use the device series with J-Link:
- Reset pin of MCU needs to be connected to reset pin of J-Link. If this is not the case, proper target connection cannot be guaranteed
ECC protected internal RAM
The device series provide ECC protected internal RAM. By default, J-Link resets the MCU on connect and initializes the RAM contents to 0x00. This is done for the following reasons:
- If a memory window in the debugger is open during the debug session and points to a non-initialized RAM region, on the next single step etc. a non-maskable ECC error interrupt would be thrown
- J-Link temporarily uses some portions of the RAM during flash programming and accesses to non-initialized RAM areas would throw non maskable ECC error interrupts
