P2020 DMA on L2 SRAM

Question asked by Pierre-Antoine Minichetti on Feb 20, 2014



When initiating a DMA transfer on the L2cache configured as an 512kb SRAM nothing happens.

Note that DMA transfers are working perfectly on the DDR and it is possible to write on the SRAM.


What is not working is DMA transfers (SRAM to DDR, DDR to SRAM and SRAM to SRAM).


I have DMAx_SRn[TE] = 1 (Transfer error : error condition during the DMA transfer)

I setted DMAx_MRn[EIE] but I'm not having any interrupt.


So if someone can help, it would be very kind.



I'll join my tcl config file.
