Yes, but it is from a userspace

Yes, but it is from a userspace

What I would like to achieve is writing to flash from "outside".
For example JTAG is an example.
Via JTAG you can write to flash( using  for example DMA - direct memory acc=
ess).
But to be able to do so, I must know the flash location.
The same/similar is true about RAM

Can you advice a solution to my goal?( finding memory/flash  address assign=
ment)?
Thanks
