43xxx_Wi-Fi project:
I added MyFile.c at this path
(43xxx_Wi-Fi_Exp\apps\snip\bluetooth_audio\MyFile1.c)
Contents of MyFile.c is as follows
/******start of MyFile.c *******/
int MyVariable;
void MyFunction()
{
MyVariable = 1;
}
/******end of MyFile.c *******/
MyFile1.c is included in makefile bluetooth_audio.mk as follows
$(NAME)_SOURCES := bluetooth_audio.c \
MyFile1.c \
bluetooth_audio_nv.c
When I compile (snip.bluetooth_audio-CYW943907WAE3) the code,compilation is successful.
As per my understanding in map file snip.bluetooth_audio-CYW943907WAE3.map
(at path 43xxx_Wi-Fi_Exp\build\snip.bluetooth_audio-CYW943907WAE3\binary)
I should be able to see the address of 'MyVariable' declared in MyFile.c
and address of 'MyFunction' defined in MyFile.c
But even after successful compilation why i am not able to see address of 'MyVariable'
and 'MyFunction'?
Solved! Go to Solution.

Hello,
Compiler optimizations might result in variables being moved to a resistor and so they do not have any address associated with them.
You can use objdump tool to check all the symbols in your program using the elf file of program:
objdump.exe --dwarf=info elf_file_name >text_file_name.txt
Besides you may have a look at this article: https://www.embeddedrelated.com/showarticle/900.php I found this interesting and relevant to your question.
