The NXP S32G3 device family consists of high-performance vehicle network processors.
Flash Banks
| Flash bank | Base address | J-Link support | Flasher support | Loader | |
|---|---|---|---|---|---|
| Name | Bank size | ||||
| QSPI Flash | 0x00000000 |  |
|
Default | up to 512 MB |
QSPI flash programming requires special handling compared to internal flash. For more information, please refer to the QSPI Flash Programming Support article.
Note:
Programming via the Cortex-M7 cores is the fastest and should therefore be used whenever possible.

Watchdog Handling
- The watchdog is disabled on connect.

Below, the debug-related multi-core behavior of the J-Link is described for each core:
Cortex-M7
Init/Setup
- The core power-on sequence is executed if the core is powered down.
Reset
- The device uses a custom reset:
- System destructive reset
Attach
- Attach is supported
Cortex-A53
Init/Setup
- Watchdogs are disabled.
- SRAM is initialized if necessary.
- A debug loop is written to SRAM.
- The partition and core power-on sequence is executed if the core is powered down.
Reset
- The device uses a custom reset:
- System destructive reset
Attach
- Attach is supported
