Hi!

My customer is needed to add additional array for storing PNA records for Prime PLC code.

But there is no free space in L36SARAM page.

To solve the probblem we want to place the arry in L8SARAM(it seems like not used). Like this:

pragma SET_DATA_SECTION("_L8SARAM_")
volatile int32 some_array[100];
#pragma SET_DATA_SECTION()

But we do not have a separate memory section for L8SARAM in prime_ec_f2806xcfg.cmd. Also, linker script can not be modified directly because its generated by Tconf tool from file prime_ec_f2806x.tcf.

How we can place the array in the L8SARAM page or in some other free space?

BR, Vsevolod.

Vsevolod,
are you building in CCS?
You should be able to add one extra linker command file with the following content, which should allocate the section _L8SARAM_ to the memory object L8SARAM:
SECTIONS {
_L8SARAM_ > L8SARAM
}

The linker command file extension should be .cmd, and the file should be located in the project's top directory.
