Browse Source 
The type of DMA for the stm32f0 devices was wrong
Its DMA is of type V2bis where the peripheral request is fixed.
The corresponding DMA cell has 2 elements.
The stm32f091 has two DMA instances.

STM32 DMA controller (V2bis) for the stm32F1 and stm32L1 soc families
STM32 DMA controller (V2bis) for the stm32F0, stm32F1 and stm32L1 soc families
This DMA controller includes several channels with different requests.
All the requests ar ORed before entering the DMA, so that only one request
