Where is my DRAM (zynqberry)
(1/1)
svenssonjoel:
Hello,
ug585 chap4 shows a picture of the zynq memory map but how do I know what memory address range correspond to my actual dram in the 128 & 512MB versions of the zynqberry? I cannot find this information in either the zynqberry TRM or the board files (or google).
Thank you

Hello,
table 4-1 DDR --> 0010_0000 to 3FFF_FFFF
In case off M version (512MB) --> its 0010_0000 to 1FFF_FFFF
See HDF view of the exported HDF, or generated linker script of a app like hello world or or generated xparameters.h on SDK

svenssonjoel:
Thank you very much.
Table 4-1 really confused me since there are many ranges of memory marked with DDR. How did you conclude that the range marked DDR at 0010_0000 is what corresponds to the actual memory?
So I guess it is more a question of how to read and understand datasheets ;)
But thanks a lot. Have a great day

Hi,
run SDK with HDF export from your ZynqBerry design.
1 See HDF from platform export
2 See Linker Script from App
3 See generated xparameters.h
