Other Parts Discussed in Thread: CC2543

Hi,

I am working on CC2543..

These lines from the map file when I compile it:

16 104 bytes of CODE memory

18 bytes of DATA memory (+ 54 absolute )
745 bytes of XDATA memory (+ 128 absolute )
64 bytes of IDATA memory
8 bits of BIT memory

after that I extend one global array by 40 bytes, I get: error:

Error[e16]: Segment XDATA_Z (size: 0x225 align: 0) is too long for segment definition. At least 0x26 more bytes needed. The problem occurred while processing the segment placement command...

I tried to go to General Options --> Stack/Heap --> Stack Sizes and to increase the XDATA from 0x100 to 0x130 or 0x200 or 0x300 but it does not help.

can you help me please what can I do?

Thanks.

Hi,

What is the type of this array? How it's defined, static?

extern unsigned char array, its global array that used in the whole project.

actually instead of increasing the Stack size, I decreased it from 0x100 to 0x0A0.

now it compiled successfully, but I'm not sure if it will cause runtime errors and global variables overflow!

what "static" declaration can affect in this case?

I was trying to understand how exactly you declared this array, and where.

The point is to place your variables outside of stack, which is pretty much limitted in this case
