error while compiling zstack for msp430f2619

Hallo Kiran, 

I am also experiencing the same problem, I am working with MSP430F5438A (from EXP5438) with CC2520. Nothing is modified, I am just trying to run the sample code and get the following similar error.

Error: 

Error[e16]: Segment HAL_OTA_CHKDL_SEG (size: 0xb0 align: 0x1) is too long for segment definition. At least 0x2 more bytes needed. The problem 
occurred while processing the segment placement command "-Z(CODE)HAL_OTA_CHKDL_SEG=0xFD14-0xFDC1", where at the moment of placement 
the available memory ranges were "CODE:fd14-fdc1" 
Reserved ranges relevant to this placement: 
fd14-fdc1 ?FILL3 
Error while running Linker

I have seen some posts, where they wrote some solutions to be:  changing the data model to large, reducing global variables/other variables and reducing the stack size. I couldnt resolve my error with the above solutions however. 

In your case, it sounds like it gets resolved, if you increase your heap size. 

Best, 

Vidya. 

thanks for reply

i tried to increase it and got some new  errors.

do u knw what are the exact values ?

but in your case the processor is different so u need to use MSP430F5438A's xcl file .. ryt?

zstack by default takes 2618's memory map.. which is not needed for us..

Dear Kiran,

When I check the options as shown above, I have seen Data 16 heap size is set to zero by default.  Change this to 64 or 128 and try it out please. This might resolve your error. Please let me know regarding the same.

Best regards, 

Vidya. 

hi vidya

thank u for the suggestions

but that didnt help much.. same error continuing.. 

i wonder why TI engineers are not responding for this.. 

thank u vey much for the reply

i also understand  what error msg says.. but my problem is not that

what values i need to set to get rid of these errors.. and wher i have to modify to what values to compile smoothly

i tried by reducing the DATA_16 n range in the ide and that is leading to some other error

if i want to make DATA_16 range 1k .. where should i do it ?

Normally, it should be as large as it requires.
You must differentiate between the DATA_16 and the DATA_16 heap. The heap is a placeholder which reserves space for use with malloc or dynamic object generation (when using C++ classes) or such. If you don't need dynamic heapspace allocation, it can be left to 0.
The 'stack size' also just places a big placeholder into the ram segment. It does not influence at all how much space the stack will take or not (a chane of this settign won't change a single bit in the generated binary). If you call a function, the stack will grow, whether you have reserved that much or not. Same for local variables in a function. THis settign jsut forces a linker error if there isn't that much memory left when all other objects have been placed. SO you might want to reduce this setting to a value that is suitable for your application (and some reserve space).
If you don't use printf and don't have large amounts local variables in your functions, some hundred bytes are enough.

You might want to set the stack size to 0 bytes or whatever teh linekr will allow as minimum, so the linker will link the project and generate a map file (enable map file generation in the linker settings). Then you can look at the map file to determine what takes all the memory in your ram segment.
