CC2652P: Can we set custom TC link key using Uniflash for ZR/ZNP during production , instead of setting from sysconfig.

Hi Dhanraj,

You can accomplish this by determining the location of the defaultTCLinkKey from the output *.map file and then modify the output hex image location directly before programming with Uniflash.  You could also specify the location of the declaration.  There are some instructions in the TI Clang User's Guide.

const uint8_t __attribute__((persistent, location(0x55FF0), used)) defaultTCLinkKey[SEC_KEY_LEN] = DEFAULT_TC_LINK_KEY;

You should be able to employ such a similar mechanism for any definitions within a SimpleLink SDK TI Clang-based project.  You will need to know which variables refer to the definition and use it within the application, and modify accordingly.
