Hi
I'm working on CycloneVsoc Dev Kit baremetal system
Now I want to use F2H sdram to transmit my data.
The draft system Interconnection:
HPS host master
|
| host order
|
SelfIP write -------ST----------| SGDMA |--------MM-------------> SDRAM
SelfIP read <-------ST---------| SGDMA |--------MM------------- SDRAM
do I need to transfer the Endian for the SGDMA?
or is there any setting to let avalon ST using little endian?
As for HPS,
HPS view of mmap is MPU one, so the address of SDRAM is from 0x00100000 to 0xC0000000, according to HPS UG,
is that the physical address or vertual one?
what is this SDRAM stands for ,? Is it the ddr3 chip on this board?
If it is, is that the place where my codes are?
how should I put/get data to sdram within and beyond this scope from HPS?
CycloneVsoc address map

Hi CAlex,
I think you can use the same software code from this design example as reference to perform the transfer for your baremetal application:
https://community.intel.com/t5/FPGA-Wiki/MSGDMA-design-example/ta-p/735335
The sdram is refering to the external sdram which is the DDR for your case.
If checking that specific start address for your baremetal application which loaded to the DDR, you can see the same application content which you have built.
Thanks.

Hi CAlex,
Maybe can check out this example link which is similar to the previous link showcasing msgdma using Nios as reference.
