Emm…yes. They are similar but different. At least the task stack layout is different. :joy:

Nice … I will check it… …!!

Happy May Day! I updated this port. Some new features have been added. support interrupt nesting use a separate ISR stack for interrupts reduce stack usage of nested interrupts IAR and CCRH are added [image] mikisama/FreeRTOS_RH850 FreeRTOS port for Renesas RH850. Contribute to mikis…

I use IAR. The ELF generated by IAR and CCRH can be debugged with IAR. The ELF generated by GCC can be debugged by IAR, but it doesn’t be fully compatible with IAR. You can build the project with CCRH and create a debug-only project with CS+. [1] [2] [3] [5] I don’t know how to simulate the …

Hi, @JonWingfield Sorry for the later reply. I didn’t notice the forum email. For RH850, there are two interrupt acknowledgments according to the settings: Direct vector method Table reference method RINT only works for the Direct vector method. When we use the Direct vector method and RINT=0 …
