About the DMA transfer to RFBI

Other Parts Discussed in Thread: AM3703

We are using AM3703.

I would like to use RFBI for connection with LCD.

(Not Bypass mode but RFBI mode)

I would like to carry out the DMA transfer of the PixelData on SDRAM to

LCD via RFBI.

I think ,in a bypass mode, in order to transmit PixelData, the following

register is set up, and DMA transfer is carried out.

 DSS.DISPC_CONTROL
 DSS.DISPC_GFX_BAj
 DSS.DISPC_GFX_ATTRIBUTES
 DSS.DISPC_GFX_ROW_INC
 DSS.DISPC_GFX_PIXEL_INC
 DSS.DISPC_GFX_FIFO_THRESHOLD
 DSS.DISPC_GFX_TABLE_BA

Is a DMA transfer possible by setting up the same register also in the case of RFBI mode?

I think that the procedure in that case is as follows.  Is realization possible?

1) It is specification of a write-in head address to RFB of LCD.

It is a Write to a CMD register at an L4 Interconnect course.

2)After that.

In order to transmit PixelData in the course of MEMORY-DMA-DISPC-LCD (RFB) , enable RFBI output (in procedure of Fig. 7-144 of TRM) .

  • Hi Makoto,


    I know this is very old thread, but I need your help here. Does it worked for you?

    I want to use RFBI mode, can you help me what are the set of registers to configure & in what sequence to configure in order to use RFBI enabled mode.

    Thanks,

    Hitesh
