Hello!
I am trying to use the DMA module in the ISS SIMCOP. I didn't find any documentation regarding SIMCOP, but some OMAP docs have usable information.
In this document (OMAP4460 Multimedia Device Silicon Revision 1.x, Version AB), at page 2364, is the description of the registers SIMCOP_DMA_CHAN_SMEM_ADDR_
I'm supposed to write the shared system memory address into this register from M3 software, and the DMA module (once triggered) will copy blocks starting from here. The register description states, the address should be written to bits [31:4], and [3:0] is reserved. I'm quite sure I need to specify a 32bit memory address somehow, so my question is:
1) How should I interpret the contents of this register?
2) How do I specify a 32bit shared memory address in 28bits?
3) Am I missing / misinterpreting something?
Thanks in advance,
Tamás
