CCS/CC1310: Predefined data at given adress in hex file

Thomas2586

Part Number: CC1310

Tool/software: Code Composer Studio

We are planing to start production soon.

We need a defined unique id in all chips, the production facility must manipulate the .hex file with the number for each device.

I am trying to figure out how to get data at a given address and have that it in my hex file.

I have this bit of code:

#define ADDRESS 0x1A000
#pragma LOCATION( myID , ADDRESS );
static char myID[5] = {0x11, 0x11, 0x11, 0x11, 0x11};

But I cant the data back anything in my hex file.

Any tips on how to achieve this?

Any input is appreciated.

Thanks

Thank you, my spelling was a bit off and no edit function.

tried to say that I cant find the data back in my hex file after build. Production need this so they know where to edit the file before flashing.

The address is used so I can use NVS_read to read back ID and some config data at run time and I also use NVS_write so that I can change any config data in the same segment at runtime if need be.

I also tried to change the code where the NVS region is configured without any luck

Thanks

Thomas

Hi and thank you for you response.

this does not solve my issue.

In production we must have full control of the unique id, the id must be unique within 24bit also.

This is also a cost issue. The production facility that program the devices can only edit the HEX file to sett the id and store the ID in a database for later use. We also want to automatically print labels with the id on.

This is now unfortunately delaying our project and we need a solution ASAP.

thanks.

Hi,

To right to an arbitrary location you can do the following:

#define LOCATION ((char*)address)

for(int i = 0;i < 5;i++){

*(LOCATION +i) = myID[i];

}
