The [DeviceFamily]family comes with a variety of multi-core options.<br>
 
Some devices from this family feature a secondary core which is disabled after reset / by default.<br>
 
Some of the are available with enabled ''lockstep'' mode, only. <br>
 
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 | XXX]]
 
*Enables debugging
 
====Reset====
 
*Device specific reset is performed, see [[XXX | 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

The Renesas ASSP easy are RISC-V based microcontrollers.

Flash Banks

Internal Flash

Flash Bank Base address Size J-Link Support
Code Flash 0x00000000 up to 128 KB YES.png
Config Flash 0x01010008 up tp 44 B YES.png
Data Flash 0x40100000 up to 4 KB YES.png

ECC RAM

  • Device has ECC RAM which has to be initialized before use.

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.

Device Specific Handling

Connect

Reset

  • The device uses normal RISC-V reset, no special handling necessary, like described here.

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.

Security

Evaluation Boards

Example Application
