Good afternoon. It is not possible to add the IVT header for the axf file, the final file is then clipped.

Input parameters:

scf - file:

#! armcc -E

#define m_interrupts_start 0x00002000
#define m_interrupts_size 0x00000400

#define m_text_start m_interrupts_start + m_interrupts_size
#define m_text_size 0x00020000 - m_interrupts_size

#define m_data_start 0x20000000
#define m_data_size 0x00020000

/* Sizes */
#if (defined(__stack_size__))
#define Stack_Size __stack_size__
#else
#define Stack_Size 0x0400
#endif

#if (defined(__heap_size__))
#define Heap_Size __heap_size__
#else
#define Heap_Size 0x0400
#endif

LR_m_text m_interrupts_start m_text_start+m_text_size-m_interrupts_size { ; load region size_region
VECTOR_ROM m_interrupts_start m_interrupts_size { ; load address = execution address
* (RESET,+FIRST)
}
ER_m_text m_text_start m_text_size { ; load address = execution address
* (InRoot$$Sections)
.ANY (+RO)
}
RW_m_data m_data_start m_data_size-Stack_Size-Heap_Size { ; RW data
.ANY (+RW +ZI)
* (NonCacheable.init)
* (NonCacheable)
}

ARM_LIB_HEAP +0 EMPTY Heap_Size { ; Heap region growing up
}
ARM_LIB_STACK m_data_start+m_data_size EMPTY -Stack_Size { ; Stack region growing down
}
}

imx-itcm-unsigned.bd:

options {
flags = 0x00;
startAddress = 0x0000;
ivtOffset = 0x00001000;
initialLoadSize = 0x00002000;
entryPointAddress = 0x00002000;
DCDFilePath = "dcd.bin";
}

sources {
elfFile = extern(0);
}

section (0)
{
}

Run elftosb:

elftosb.exe -d -f imx -V -c imx-itcm-unsigned.bd -o ivt_ECP_RT1052_Release.bin ECP_RT1052_Release.axf

 

The elftosb utility is very unstable, constantly crashes.

For example, the following situation leads to departure:

RW_m_data m_data_start m_data_size-Stack_Size-Heap_Size { ; RW data
.ANY (+RW +ZI)

.ANY (+RO)
* (NonCacheable.init)
* (NonCacheable) 
}

 

Tell me how to properly process the elf file?

Sorry for bad English
