|

|
After any reset, the boot ROM on the AM43XX SOC
|
||
|
|
searches the boot media for a valid boot image.
|
||
|
|
For non-XIP devices, the ROM then copies the
|
||
|
|
image into internal memory.
|
||
|
|
For all boot modes, after the ROM processes the
|
||
|
|
boot image it eventually computes the entry
|
||
|
|
point address depending on the device type
|
||
|
|
(secure/non-secure), boot media (xip/non-xip) and
|
||
|
|
image headers.

help
|
||
|
|
During the device boot, the public ROM uses the top of
|
||
|
|
the public L3 OCMC RAM to store r/w data like stack,
|
||
|
|
heap, globals etc. When the ROM is copying the boot
|
||
|
|
image from the boot media into memory, the image must
|
||
|
|
not spill over into this area. This value can be used
|
||
|
|
during compile time to determine the maximum size of a
|
||
|
|
boot image. Once the ROM transfers control to the boot
|
||
|
|
image, this area is no longer used, and can be reclaimed
|
||
|
|
for run time use by the boot image.
