Hi,
I'm trying to have a certain variable lets say "const uint8_t Version[4] = {0x01,0x02,0x03,0x04}" at a specific place memory region.For doing so i've used the section attribute of "__attribute__((section("name"))) variable attribute".Here is the definition:const uint8_t Version[4] __attribute__((section("VER_SECTION"))) = {0x01,0x02,0x03,0x04};
I've also added another execution region in the corresponding scatter file like below:ER_VER __VER_BASE __VER_SIZE { opcodes.o (VER_SECTION) }
However during link stage i got the below error:" Warning: L6329W: Pattern opcodes.o(VER_SECTION) only matches removed unused sections"
I though that using the "--keep" linker flag will help to solve the problem so i tried:--keep="opcodes.o (VER_SECTION)"but it didn't help.Your help will be appreciated.
BTW, regarding "section attribute" usage i understood that "The section attribute specifies that a variable must be placed in a particular data section". While my variable is of const uint8_t which means it goes into RO/CODE area - maybe this is the problem root cause?
Thanks,Ronen
Pls ignore my previous post.I had a mistake in using the linker --keep flag.I was using the section name instead of the variable name itself.Now it is working as expected.Ronen
