About IRQController.NVIC & CPU.CortexM Classes

[fdsgdshn]

Hi,

I had a code that previously worked in Renode. However, after updating the repository, I noticed that the project no longer functions. Indeed, when I go to the src/peripherals path, I see that the IRQControllers.NVIC extension is no longer present. What do I need to do to be able to use this IRQController? Can you provide some guidance?

nvic: IRQControllers.NVIC @ sysbus 0xE000E000
priorityMask: 0xFF
systickFrequency: 120000000
IRQ -> cpu@0
cpuId: 0x410FC241

cpu: CPU.CortexM @ sysbus
cpuType: "cortex-m4"
nvic: nvic

Error message:
Error E25: Could not find suitable constructor for type 'Antmicro.Renode.Peripherals.IRQControllers.NVIC'.
Constructor selection report:
Considering ctor Antmicro.Renode.Peripherals.IRQControllers.NVIC with the following parameters: [Antmicro.Renode.Core.IMachine, System.Int64 (optional), System.Byte (optional), System.
Boolean (optional)].
Parameter 'machine' of type 'Antmicro.Renode.Core.IMachine' filled with default value = 'machine'.

Thank you very much.
Best regards.

Hi @fdsgdshn, thanks for reporting the issue.

Recent changes to the NVIC model (renode/renode-infrastructure@212ff2e) removed the cpuId property - it's now automatically taken from the CPU object itself (please note, that it might not be the same value as you used to provide - question if that's an issue in your case?).

The simplest solution for the error you observe is to remove the cpuId: 0x410FC241 line from repl completely.
