CC1310: MAC address broken in SDK 2.40

Part Number: CC1310

I had previously accessed the MAC address using the following code:

#include <ti/devices/cc13x0/inc/hw_fcfg1.h> //for mac address register
            uint32_t * addrPtr = (uint32_t *)(FCFG1_BASE + FCFG1_O_MAC_BLE_0);

(I only needed the first 4 bytes). That worked fine until I updated to 2.40 and now it returns zero when I de-reference that pointer. Any thoughts? Nothing else changed on the hardware. I did however have to squash the usual breaking changes when switching between SDK's

    CC1310 is not BLE chip and it won't have BLE MAC address. It should be 15.4 MAC address so I suppose you should use "uint32_t * addrPtr = (uint32_t *)(FCFG1_BASE + FCFG1_O_MAC_15_4_0);" instead of "uint32_t * addrPtr = (uint32_t *)(FCFG1_BASE + FCFG1_O_MAC_BLE_0);"

    Well that makes sense. I guess when I wrote that code I was using a 1350 sensortag, so that would explain it. I still had the code in there, but wasn't actually using it since the changeover.


    Thanks!
