STM32F0 with ADC and DMA with Renode

Question

I'm trying to run an application on Renode that uses ADC and DMA for the STM32F030F4P, I created a stm32f0.repl file with the dma and adc as follows:

dma: DMA.STM32LDMA @ sysbus 0x40020000
    [0] -> nvic@[9]

adc: Analog.STM32F0_ADC @ sysbus 0x40012400
    referenceVoltage: 3.3
    externalEventFrequency: 1000
    -> nvic@12
    dmaChannel: 1
    dmaPeripheral: dma

When I run Renode, I get the following error:

For parameter 'dmaPeripheral' of type 'Antmicro.Renode.Peripherals.DMA.IDMA' found attribute at C:\Program Files\Renode\platforms\cpus\stm32f0.repl:151:5 with value [ReferenceValue: dma]
  Parameter is not assignable from the reference value, constructor rejected.
  At C:\Program Files\Renode\platforms\cpus\stm32f0.repl:146:6:
  adc: Analog.STM32F0_ADC @ sysbus 0x40012400
       ^

What is the correct value for dmaPeripheral?

As it's optional, you can remove it completely. This would lead to DMA not being used.

It seems that what you have written should be doable, and it's a bug that it's not possible. The STM32LDMA should implement the IDMA interface and it doesn't.

I would suggest filing a bug on Renode's GitHub
