Error[e104]: Failed to fit all segments into specified ranges.

Hello All,

I am building the ZNP using Z-Stack 1.2.2 and upgrading from 1.2.1. I came across an error when I tried to use Certicom ECC library and enable ZCL Key Establishment Cluster. Here is the error in IAR. Error[e104]: Failed to fit all segments into specified ranges. Problem discovered in segment BANKED_CODE. Unable to place 121 block(s) (0x381dd 
byte(s) total) in 0x36d74 byte(s) of memory. The problem occurred while processing the segment placement command 
"-P(CODE)BANKED_CODE=_CODE_START-_CODE_END,0x18000-0x1FFFF,0x28000-0x2FFFF,0x38000-0x3FFFF,0x48000-0x4FFFF,0x58000-0x5FFFF,0x
68000-0x6FFFF,0x78000-0x7C7FF", where at the moment of placement the available memory ranges were 
"CODE:57aa-7ff7,CODE:7fff-7fff,CODE:182db-1ffff,CODE:28000-2ffff,CODE:38000-3ffff,CODE:48000-4ffff,CODE:58000-5ffff,CODE:68000-6ffff,CODE:78000-7c7ff

What I changed on the latest Z-Stack version 1.2.2 is:

 1. Change the CC2530.ewp project file to use Certicom library:

<option>

          <name>Linker Extra Options Edit</name>

          <state>-C $PROJ_DIR$\..\..\Libraries\Certicom\bin\libecc.r51</state>

          <state>-C $PROJ_DIR$\..\..\Libraries\TI2530DB\bin\AllDevice-Pro.lib</state>

          <state>-C $PROJ_DIR$\..\..\Libraries\TI2530DB\bin\Security.lib</state>

          <state>-C $PROJ_DIR$\..\..\Libraries\TIMAC\bin\TIMAC-CC2530.lib</state>

          <state>-M(CODE)[(_CODEBANK_START+_FIRST_BANK_ADDR)-(_CODEBANK_END+_FIRST_BANK_ADDR)]*_NR_OF_BANKS+_FIRST_BANK_ADDR=0x8000</state>

        </option>

 2. Change the znp.cfg to enable the ZCL Key Establishment Cluster:

// Define this flag to enable ZNP implementation of the ZCL_KEY_ESTABLISHMENT_ENDPOINT and task.

-DTC_LINKKEY_JOIN

-DECCAPI_283_DISABLED

// Define this flag to enable ZNP implementation of the ZCL_KEY_ESTABLISHMENT_ENDPOINT and task.

-DZCL_KEY_ESTABLISH

3. Add the Certicom library into Z-Stack Home 1.2.2.42930\Projects\Libraries

 

Then when I compiled using IAR, the error occurred. I read some posts about this error. Some people said change the INT_HEAP_LEN to 1000. It does not work for me and I think reducing the heap significantly will bring about some other potential issues? Also I tried to change D_CODE_END in linker file cc2530-sb.xcl to 0xFFFF. The error disappeared but is it really okay to do that? Could someone please give me some ideas on this error? 

Thanks,

QK Sun

    Sorry you have hit this issue.

    Changing D_CODE_END to 0xFFF may cause an issue with CONST data:

    // Define segments for const data in flash.
    // First the segment with addresses as used by the program (flash mapped as XDATA)
    -P(CONST)XDATA_ROM_C=0x8000-0xFFFF

    However you could reduce the constant data and increase the D_CODE_END, as long as you can find a balance that compiles. The other option would be to reduce the FLash used for NV storage.
