TMS320F28065: How to protect generated Intel .HEX file

Dear Sir/ Madam,

Please tell me how to protect .HEX Intel file generated in CCS.

We send HEX files for upgradation in different places, we wanted to ensure that reverse code would not be available if we share .HEX file.

If there are different methods for secure update of MCU Pl. let me know.

hi Ravi ,

How do you plan on loading this code onto the device ?

Is it using CCS or some other equivalent tool ?

I believe we don't have anything directly if using the tool .

Maybe we could use some encryption / decryption.

Regards.

Madam,

We upload firmware through C2prog in SCI boot

hi,

I believe there is nothing straightforward by the c2prog tool.

Since the keys in the tool are primarily to unlock the device and then flash the code.

I will check internally and get back if there is any other way.

Regards.

Hi Ravi,

Could you please use Serial flash programmer to upload the firmware.

Serial flash programmer examples:

Here you may try to encode the date sent via the flash programmer and decode through kernel before programming the device.

Please go through application note and let us know if this method works for you.

Thanks,

Katta
