LiteDRAMDMAWriter cannot write accurate data to a specific address?

[Prigana]

Hello,

I use the LiteDRAMDMAWriter module of Litedram.dma . I have a problem, I would like to transmit data acquired in hard and write them in my ram without going through the soft side. For that, I wanted to try the LiteDramDmaWriter module with basic tests like writing (with sink.data) to a precise address (with sink.address) but it does not work. I checked that my sdram is well initialized.

My question is: is it possible to write just one byte to a specific address using the LiteDRAMDMAWriter module only in hardcore in python without going through softcore (except for the initialization of the sdram)?

Here is an example of a writing request I made in an fsm :

Here is my module initialization:

I set the valid to 1
