CCS generates executable file, checking map file does not show a problem, function are correctly placed, but there is a warning:
warning #10247-D: creating output section ".TI.ramfuncs" without a SECTIONS specification
Here is "2837x_RAM_lnk_cpu1.cmd" file:

warning #10247-D: creating output section ".TI.ramfuncs" without a SECTIONS specification
Finished building target: "Wolfspeed_cpu1.out"
please see two lines above, highlighted in bold red.
I can not figure out how to remove the warning. Here is source code that requests a function to be placed in ".TI.ramfunc" segment:
#pragma CODE_SECTION(ADC_A1_Interrupt, ".TI.ramfunc");
interrupt void ADC_A1_Interrupt(void)
{
// function body here
}
I am using CCS 12.5.0
Thank you.
