Hello

How we can define a not initialized variable in IAR AVR C compiler?

I want to have a variable in AVR internal SRAM that the program does not reset it to 0 at startup.
 

Define your variable with __no_init prefix.
 

When I use __no_init like as:

__no_init INT16U SendOkCounter,SendFailCounter;

the compiler give this error:

Error[e16]: Segment NEAR_N (size: 0x4 align: 0) is too long for segment definition. At least 0x4 more bytes needed.
The problem occurred while processing the segment placement command
"-Z(DATA)NEAR_N=_..X_EXT_NV_BASE:+_..X_EXT_NV_SIZE", where at the moment of placement the available
memory ranges were "DATA:10ff--1"


How I can solve the problem?


note:
typedef unsigned short INT16U; /* Unsigned 16 bit value */
