STM32F30x: DMA interrupt for Channel > 1 not raised

Question asked by Wawrzyniak.Laurent on May 28, 2013
I use a  DMA1-CH1 associated to TIM4-CH1 to feed data to GPIOC.
I use the DMA IRQ CH1 to know when Transfer Complete is done.
In this case all works as expected.
I have a problem when used another DMA channel, for instance DMA1-CH6 with TIM3-CH1 or any other combination ( see p 173 of STM32F30X reference manuel).
The problem is that no more IRQ is raised for DMA channel different of 1 ?
What could happen ?
Regards
