Hi,
I'm trying to create a new memory layout and mmu mapping for
my special board, similar but not same as Cirrus EDB7212 -using
eCos v1_3_1.
I want to build and program into flash a standalone application, the
hello world, for example, possibly without using Gdb stuff.
I want just to put the program into flash, and the application must
be running after power cycle.
>From the eCos User's Guide (page 89), i see that to change
memory layout it is necessary to modify the mlt_* files in
/ecos/packages/hal/arm/edb7xxx/v1_3_1/include/pkgconf/, and ,
for a rom application, I intend to modify the following files:
mlt_arm_edb7212_rom.h
mlt_arm_edb7212_rom.ldi
mlt_arm_edb7212_rom.mlt
For the mmu, I've seen that this file:
hal_platform_setup.h (/ecos/packages/hal/edb7xxx/v1_3_1/include)
does the mmu initialization.
Is there any other important file to take care of?
Thankyou
- Nicola
