Problems when running the EndPoint code in EZ430-RF2500 wireless sensor network demo with CCS 6.1.3

Hello Everyone,

I am trying to set up the demo application for the EZ430-RF2500 kit by using CCS 6.1.3.

To make it compile and run on the Acces Point side I had to make some compiler configuration changes, namely:

-Set the compiler version to TI v15.12.1.LTS

-Change output version to eabi(ELF)

-Change runtime support library to rts430_eabi.lib.

The AP seems to be working fine with these settings, however the End device side did not seem to do anything. I tried debugging and the execution seems to get stuck in the nwk_frame.c file, nwk_buildFrame function at the following line:

....
PUT_INTO_FRAME(MRFI_P_PAYLOAD(&fInfoPtr->mrfiPkt), F_ENCRYPT_OS, 0);
PUT_INTO_FRAME(MRFI_P_PAYLOAD(&fInfoPtr->mrfiPkt), F_PORT_OS, port);
PUT_INTO_FRAME(MRFI_P_PAYLOAD(&fInfoPtr->mrfiPkt), F_TRACTID_OS, sTRACTID);
while (!(++sTRACTID)) ;  /* transaction ID can't be 0 */  /*<-------- this line here is where it gets stuck*/
PUT_INTO_FRAME(MRFI_P_PAYLOAD(&fInfoPtr->mrfiPkt), F_RX_TYPE, sMyRxType);
PUT_INTO_FRAME(MRFI_P_PAYLOAD(&fInfoPtr->mrfiPkt), F_HOP_COUNT, hops);
....

The while loop is never exited as the sTRACTID is never updated. By looking at the address of the variable it points to a location outside RAM, somewhere in the register address space which. This is confirmed by the map file also, the .data segment is located in the area dedicated for peripheral registers:

                00000068    00000003     nwk_mgmt.obj (.data)

I checked the map file of the AP and I found the same thing although the AP seems to be working fine (at least the temperature reading and serial data sending).

What am I missing here? Any help would be very appreciated.

Thanks in advance,

Stefan
