Posted on April 12, 2007 at 21:04Hi there,
My code size is much smaller to fit into RAM. Hence, I want to ran the entire code from RAM by copying all code from Flash to RAM. I learned that I can achieve that by using adding this line, The line,
* (InRoot$$Sections). I've got the memory map configured accordingly, please refer below for details. However, the code seems to be not working properly after __main.
Can someone pleas advise. Thanks in advance.
myFlash.scf
USER_MODE 0x40000000 0x40000 ; Load Region
{
FLASH 0x40000000 ; Execution Region
{
;71x_vect.o (Vect, +First) ; Uncomment this if Vector is placed in Flash( comment the corresponding RAM Line )
71x_init.o (Init, +First)
* (InRoot$$Sections)
;* (+RO)
}
; built-in RAM = 64kBytes
RAM 0x20000000 0x10000
{
71x_vect.o (Vect, +First) ; Uncomment this if Vector is placed in RAM( comment the corresponding FLASH line )
* (+RO)
* (+RW)
* (+ZI)
}
; Heap will grow just above ZI region :
; This Symbol is exported to ''71x_init.s'' file
HEAP +0 EMPTY 0x400
{
}
; Stack Base address exported to ''71x_init.s'' file ( Top of SRAM )
STACK 0x2000F000 EMPTY -0x0
{
}
}
