Dear All:
In ARM E7T RedBoot User Manual:
Physical Address Range C B Description
0x00000000 - 0x0007ffff Y N SDRAM
0x03f f 0000 - 0x03f f ffff N N Microcontroller registers
0x01820000 - 0x0187ffff N N System flash (mirrored)
In the ARM E7T board there are 512KB SRAM, 512KB Flash memory. compared
with the above redboot memory setting confused me.
Q1: As indicated above in RedBoot: 0x00000000 - 0x0007ffff SRAM ( ?=
(7ffff/1024) KB SRAM (am I right?) ) But where is the on board 512KB SRAM?
(or maybe I made the wrong way)
Q2: What is the meaning of "mirrored" in "System flash(mirrored)"?
Thanks a lot.
Best regards!
