Flash Banks
Internal Flash
Flash Bank | Base address | Size | J-Link Support |
---|---|---|---|
Main flash (NS) | 0x00000000 | Up to 2 MB | |
Main flash (S) | 0x10000000 | Up to 2 MB |
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 MCXN547 & MCXN947. The default loader is marked in bold.
Device | Base address | Maximum size | Supported pin configuration |
---|---|---|---|
QSPI flash (NS) | 0x80000000 | 256 MB | *Default CS@P3.0 SCLK@P3.7 D0@P3.8 D1@P3.9 D2@P3.10 D3@P3.11 |
QSPI flash (S) | 0x90000000 | 256 MB | *Default CS@P3.0 SCLK@P3.7 D0@P3.8 D1@P3.9 D2@P3.10 D3@P3.11 |
ECC RAM
- Device has ECC RAM with various settings.
Multi-Core Support
Before proceeding with this article, please check out the generic article regarding Multi-Core debugging here.
In below, the debug related multi-core behavior of the J-Link is described for each core:
Main core CPU0(CM33)
Init/Setup
- 64KB RAMC @ 0x20010000 is used, if it set to ECC_ENABLE, it is initialized.
- Enables debugging
Reset
- Device specific reset is performed.
Attach
- Attach is supported if RAMC is not set to ECC_ENABLE.
Secondary core CPU1(CM33)
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, but will halt the CPU.
Attach
- Attach is supported
Device Specific Handling
Reset
The J-Link performs a device specific reset sequence. The reset is executed for the main core, only. Reset of the main core, resets / disables the secondary core if used in parallel.
