DMA works only first time

Hi,

I'm using ADC and DMA. For learning purposes no interrupts, just polling LIFR. Staring conversion with ADC_CR2_SWSTART. As soon as TCIF is set,  I'm writing 1 to ALL flags to LIFCR (LIFR becomes 0) then re-enabling DMA. Do ADC_CR2_SWSTART again and no more flags in LIFR...EOC flag for ADC is set.
Why is that? What am I missing?
