Hi,
With H7 the mapping is simple, we can use multiple streams at the same time, one channel per stream.
But with L4 , it seems to be more complex, especially usage of "channel" terminology:
For L4, Is it that we can use multiple channels ?
Thanks,

Yes, you can use multiple channels at once. All 14 if you want.

If the L4 is like the F7, it doesn't have a dmamux. Consult the dma section in the reference manual to find the table showing which dma channel and stream is connected to each source. Yes, the stream/channel thing is confusing.
I could always be wrong, but i think the dmamux is new for the H7 series?

Thanks, but for L4, cis it correct to say that multiple channels can be used at the same time ?

Read the first page of the DMA controller chapter in the reference manual.
