NXP RW61x

The NXP RW61x are Cortex_M33 based Wireless MCUs with Integrated Radio: 1x1 Wi-Fi® 6 + Bluetooth® Low Energy 5.3.

Flash Banks

External Flash

Flash Bank	Base address	Size	J-Link Support
QSPI	0x08000000	Up to 128MB

QSPI Flash

QSPI flash programming requires special handling compared to internal flash. For more information about this, please see the QSPI Flash Programming Support article.
J-Link supports multiple pin configurations for [DEVICE]. The default loader is marked in bold.

Device	Base address	Maximum size	Supported pin configuration
[DEVICE]	[BANK_BASE_ADDRESS]	[MAX_SPI_FLASH_SIZE] MB	[LOADER_NAME] [LOADER_NAME] [LOADER_NAME]

ECC RAM [OPTIONAL]

• Describe ECC RAM restriction here.

Vector Table Remap [OPTIONAL]

• Describe Vector Table Remap here..

Watchdog Handling

• The device does not have a watchdog.
• The device has a watchdog [WATCHDOGNAME].
• The watchdog is fed during flash programming.
• If the watchdog is enabled, it is turned off during flash programming and turned back on afterwards.

Multi-Core Support [OPTIONAL]

Before proceeding with this article, please check out the generic article regarding Multi-Core debugging here.
The [DeviceFamily]family comes with a variety of multi-core options.
Some devices from this family feature a secondary core which is disabled after reset / by default.
Some of the are available with enabled lockstep mode, only.
In below, the debug related multi-core behavior of the J-Link is described for each core:

Main core

Init/Setup

• Initializes the ECC RAM, see XXX
• Enables debugging

Reset

• Device specific reset is performed, see XXX

Attach

• Attach is not supported because the J-Link initializes certain RAM regions by default

Secondary core(s)

Init/Setup

• If the main core session has not been started / debugging is not enabled yet, the secondary core executes the enable debug sequence.
• If the secondary core is not enabled yet, it will be enabled / release from reset

Reset

No reset is performed.

Attach

• Attach is supported / desired

Device Specific Handling

Reset

• The devices uses normal Cortex-M reset, no special handling necessary, like described here.
• The devices uses Cortex-M Core reset, no special handling necessary, like described here.
• The devices uses Cortex-M Rest Pin, no special handling necessary, like described here.
• The devices uses Cortex-A reset, no special handling necessary, like described here.
• The devices uses Cortex-R reset, no special handling necessary, like described here.
• The devices uses ARMv8-A reset, no special handling necessary, like described here.
• The devices uses ARMv8-R reset, no special handling necessary, like described here.
• The device uses custom reset:.....

Limitations

Dual Core Support

Some XXX devices feature a second core. Right now, the J-Link software does support the main core, only. Support for the second core is planned for future versions.

Attach

Attach is not supported by default because the J-Link initializes certain RAM regions by default.
