Hi,
My team recently supported a customer issue regarding compiling code that uses the .TI.persistent section. On compiler v15 this project compiled clean. However, with v21.6.0 LTS it fails with this message:
Invoking: MSP430 Linker "C:/ti/ccs1110/ccs/tools/compiler/ti-cgt-msp430_21.6.0.LTS/bin/cl430" -vmspx --use_hw_mpy=F5 --advice:hw_config=all --define=CTPL_STACK_SIZE=160 --define=__MSP430FR2433__ -g --printf_support=minimal --diag_warning=225 --diag_wrap=off --display_error_number --abi=eabi --silicon_errata=CPU21 --silicon_errata=CPU22 --silicon_errata=CPU40 -z -m"calendar_tamper_detect_gui_ccs.map" --heap_size=160 --stack_size=160 --cinit_hold_wdt=on -i"C:/ti/ccs1110/ccs/ccs_base/msp430/include" -i"C:/ti/ccs1110/ccs/ccs_base/msp430/lib/5xx_6xx_FRxx" -i"C:/ti/ccs1110/ccs/tools/compiler/ti-cgt-msp430_21.6.0.LTS/lib" -i"C:/ti/ccs1110/ccs/tools/compiler/ti-cgt-msp430_21.6.0.LTS/include" --reread_libs --diag_wrap=off --display_error_number --warn_sections --xml_link_info="calendar_tamper_detect_gui_ccs_linkInfo.xml" --use_hw_mpy=F5 --rom_model -o "calendar_tamper_detect_gui_ccs.out" "./Source/GUIComm_JSON.obj" "./Source/RTC_Calendar.obj" "./Source/callbacks_JSON.obj" "./Source/ctpl_msp430fr2433.obj" "./Source/ctpl_pre_init.obj" "./Source/main.obj" "./Source/MSP430_GUI/MSP430_GUI.obj" "./Source/MSP430_GUI/jsmn/jsmn.obj" "./Source/MSP430_HAL/HAL_GUIComm_UART.obj" "./fram-utilities/ctpl/ctpl.obj" "./fram-utilities/ctpl/ctpl_low_level.obj" "./fram-utilities/ctpl/ctpl_low_level_macros.obj" "./fram-utilities/ctpl/peripherals/ctpl_adc.obj" "./fram-utilities/ctpl/peripherals/ctpl_adc10_b.obj" "./fram-utilities/ctpl/peripherals/ctpl_adc12_b.obj" "./fram-utilities/ctpl/peripherals/ctpl_captio.obj" "./fram-utilities/ctpl/peripherals/ctpl_comp_d.obj" "./fram-utilities/ctpl/peripherals/ctpl_comp_e.obj" "./fram-utilities/ctpl/peripherals/ctpl_crc16.obj" "./fram-utilities/ctpl/peripherals/ctpl_crc32.obj" "./fram-utilities/ctpl/peripherals/ctpl_cs.obj" "./fram-utilities/ctpl/peripherals/ctpl_dmax_3.obj" "./fram-utilities/ctpl/peripherals/ctpl_dmax_6.obj" "./fram-utilities/ctpl/peripherals/ctpl_ecomp.obj" "./fram-utilities/ctpl/peripherals/ctpl_eusci_a.obj" "./fram-utilities/ctpl/peripherals/ctpl_eusci_b.obj" "./fram-utilities/ctpl/peripherals/ctpl_fram.obj" "./fram-utilities/ctpl/peripherals/ctpl_lcd_c.obj" "./fram-utilities/ctpl/peripherals/ctpl_lcd_e.obj" "./fram-utilities/ctpl/peripherals/ctpl_mpu.obj" "./fram-utilities/ctpl/peripherals/ctpl_mpy32.obj" "./fram-utilities/ctpl/peripherals/ctpl_pmm.obj" "./fram-utilities/ctpl/peripherals/ctpl_port.obj" "./fram-utilities/ctpl/peripherals/ctpl_port_int.obj" "./fram-utilities/ctpl/peripherals/ctpl_rc.obj" "./fram-utilities/ctpl/peripherals/ctpl_ref_a.obj" "./fram-utilities/ctpl/peripherals/ctpl_rtc.obj" "./fram-utilities/ctpl/peripherals/ctpl_rtc_b.obj" "./fram-utilities/ctpl/peripherals/ctpl_rtc_c.obj" "./fram-utilities/ctpl/peripherals/ctpl_sac.obj" "./fram-utilities/ctpl/peripherals/ctpl_sfr.obj" "./fram-utilities/ctpl/peripherals/ctpl_sys.obj" "./fram-utilities/ctpl/peripherals/ctpl_timer_2.obj" "./fram-utilities/ctpl/peripherals/ctpl_timer_3.obj" "./fram-utilities/ctpl/peripherals/ctpl_timer_5.obj" "./fram-utilities/ctpl/peripherals/ctpl_timer_7.obj" "./fram-utilities/ctpl/peripherals/ctpl_tri.obj" "./fram-utilities/ctpl/peripherals/ctpl_wdt_a.obj" "../lnk_msp430fr2433.cmd" -llibmath.a -llibc.a <Linking> error #10367-D: output section ".TI.persistent" cannot mix noinit sections with sections that require initialization.

I believe the code the linker is erring on resides in two files:
# ctpl_msp430fr2433.c
#if defined(__TI_COMPILER_VERSION__)
#pragma PERSISTENT(ctpl_PORTA_storage)
#elif defined(__IAR_SYSTEMS_ICC__)
__persistent
#endif
uint16_t ctpl_PORTA_storage[CTPL_PORT_INT_STORAGE_LENGTH] = {0};
; ctpl_low_level.asm
; FRAM stack copy
ctpl_stackCopy .usect ".TI.persistent",CTPL_STACK_SIZE,2
; RAM copy
.if $defined(CTPL_RAM_SIZE)
ctpl_ramCopy .usect ".TI.persistent",CTPL_RAM_SIZE,2
.endif
; Low level state variables
ctpl_mode .usect ".TI.persistent",2,2
ctpl_state .usect ".TI.persistent",2,2
ctpl_stackUsage .usect ".TI.persistent",2,2
The linker message says it cannot mix NOINIT and non-NOINIT data inside .TI.persistent (although I'm assuming that the message regards persistent data as NOINIT).
Is it possible to mark the symbols defined by the .usect as NOINIT? Or is there a better way to work around this?
