Defining C# models with multiple register banks

[WybrenAkker]

Hi,

I am currently trying to create a C# model of the ICM-42688-P (High precision 6-axis motion tracking device with a gyroscope and accelerometer).

I am facing a problem defining the registers, as this sensor has 5 different register banks. These all have a unique address space so some registers between banks "share" addresses.

Does Renode have a way of implementing multiple register banks/maps within a single sensor/peripheral? I can't find anything in the docs on this.

If not, I was thinking about mapping the "real" register addresses to faked Renode addresses, as if all registers were in a single bank. However, it would be great if Renode had something for this scenario.

Thanks!

Hi @WybrenAkker , thanks for reaching out.

I assume what you mean is that you can switch between banks by setting some configuration register?

What we are currently working on is a way to provide a selector to register definition to be able to define this in a single data structure. Right now you can follow this example: https://github.com/renode/renode-infrastructure/blob/master/src/Emulator/Peripherals/Peripherals/Sensors/OV2640.cs#L78

Here we switch the RegistersCollection to point to different banks. For now this should address your issue, until we have a more idiomatic way of defining banks.

That's exactly what I was looking for, thanks!
