Using renode API in C#

[asmitaj08]

Hi,
The renode doc shows how we can access its APIs like Start, setHooks, etc. either via executing these within that renode terminal or passing it though a .resc or a python script. Is there any doc , which exposes its APIs that can be natively used within any c# script?
Also, is the breakpoint set possible only via gdb?
Thank you!!

Hi @asmitaj08

I assume that by C# script you mean .resc scripts? They are not strictly C#, as they also support our internal Python engine and have their own syntax/grammar .

Unfortunately, it's almost impossible to describe the whole API, as we try to expose the whole interface - it's not hand written, but rather autogenerated.

For now I have to refer you to our documentation and scripts for samples.

Regarding breakpoints, look for AddHook in https://renode.readthedocs.io/en/latest/basic/using-python.html#cpu-hooks

A short snippet would be cpu AddHook 0xYOURADDRESS "self.Pause()"

And then resume with cpu Resume.

Having said that, GDB interface is typically easier to use.

You can also use hook to change execution mode of the CPU at given address:

cpu AddHook 0x80009000 "self.ExecutionMode = Antmicro.Renode.Peripherals.CPU.ExecutionMode.SingleStepNonBlocking"

This will make CPU stop at 0x80009000 and switch to the single stepping mode. Now you can use cpu Step to iterate over instructions.
