I need to work on a large contiguous memory zone for image processing,
but I don’t find how reserve this large memory zone (10 Mo).
I’m working with uclinux 2.6.17, ColdFire m5329, with 64Mo DDRAM.
I have tried to reserve it with malloc which returns NULL.
I have tried to address it “manually” between 0x43000000 and 0x43FFFFFF
after having reduced the uclinux memory space declaration to 48 Mo, but
the uclinux fails during GDBserver access with messages like :
Phillppe,
One way i've seen and/or done was to remove the large region from the
memory map of the OS. If it must use and MMU, assign one static entry
in the MMU for it. Then set up a unique section for it in the memory
mapping outside the usage of the OS and access it directly. Though i'm
not sure you are looking to bypass the OS.
