CRC32 | binpack utility | Image info header | How to add Image info header for binpack to store length and crc of image at that location ?

Sanchit Mehra

I am considering adding the CRC Check onto my application image.

I am using : binpack – I <input.bin> -o <output.bin>

This will add the length and crc32 on the 8 word image header.

But, now the question is how can I add that 8 words space onto my application image, so that binpack can store the calculated length and crc32 at that location.

How to insert the image info header at the top of the vector table? So that binpack can insert the length and crc32 onto that!

Hello Sanchit

Before generating the binary you need to add the information in the startup file where the interrupt vector is located. The 8 words(2 of which have to be initialized with the pattern specified in the documentation) have to be at the end of the interrupt vector

Hello Amit,

My startup file looks like

#pragma DATA_SECTION(g_pfnVectors, ".intvecs")
void (* const g_pfnVectors[]) (void) =
{

..
}

Can you pls guide me , how and where should I insert that header?

Thanks,

Hello Sanchit

Add the following after the last entry in the table and before the closing braces.

(void (*)(void))0xFF01FF02, // HEADER PREFIX 0
(void (*)(void))0xFF03FF04, // HEADER PREFIX 1
(void (*)(void))0xFFFFFFFF, // HEADER IMAGE LEN
(void (*)(void))0xFFFFFFFF, // HEADER CRC32
(void (*)(void))0xFFFFFFFF, // HEADER Reserved
(void (*)(void))0xFFFFFFFF, // HEADER Reserved
(void (*)(void))0xFFFFFFFF, // HEADER Reserved
(void (*)(void))0xFFFFFFFF // HEADER Reserved

Hi,How to do the same for an application with TI RTOS? I am not able to find startup file

Hello Sajmal

I believe you need to check with TI-RTOS as to how they may map with startup vector.
