The Realtek Ameba D are dual core (K0/K4) microprocessors with WIFI and Bluetooth.
Flash Banks
Internal Flash
| Flash Bank | Base address | Size | J-Link Support | Limitations |
|---|---|---|---|---|
| QSPI | 0x08000000 | 4 MB |  |
only for RTL872xDF devices |
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 |
|---|---|---|---|
| RTL872xCS | 0x08000000 | 16 MB |
|
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 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.
