Hi, I wrote an application in a 8051 device containing several modules. One of them needs some certification and after that it can no longer be modified. To ensure this a CRC is computed on the firmware file.
The problem is that after certificates the other modules need to be modified and this will affect the firmware CRC even if I didn't modify the certified module.
The solution would be to somehow isolate the certified module in a separate firmware file and the just load both files into the device.
Is there any way to do this?
