MSP430F2419: relocation truncated to fit: R_MSP430_16 against symbol `memcpy' defined in .text section in /usr/msp430/lib/libc.a(memcpy.o) + Math library problems x.c:(.text+0x36e): undefined reference to `isfinite'

The not fitting into ROM error suggests that you neglected to add "-mlarge" to your msp430-elf-gcc options.

It appears that you are using cmake which I have never used so that could be causing problems as well.

Hi David,

thank you for your quick response. Its basically the problem of linker script. I need to properly define my sections. This is generated automatically from CCS. This my linker script:

Gcc has linker script(s) and knows how to find them if you tell it which MCU you are using. An example very simple makefile:

GCC_DIR = /usr/ti/gcc
SUPPORT_FILE_DIRECTORY = $(GCC_DIR)/include
CC = $(GCC_DIR)/bin/msp430-elf-gcc
CPU = msp430fr5969
CFLAGS = -g -mmcu=${CPU} -I $(SUPPORT_FILE_DIRECTORY)  -Wall  -Wl,--gc-sections -mlarge

a.out: timer.c
        $(CC) $(CFLAGS) -O3 timer.c

You will have lots of problems with your script. I will not look for all of them but that single region for vectors will not work. Gcc puts each vector into its very own 2 byte section:

 __reset_vector :
  {
    KEEP (*(__interrupt_vector_32))
    KEEP (*(__interrupt_vector_reset))
    KEEP (*(.resetvec))
  } > RESETVEC

Hi David, 

thank you for your reply. I found out that I need only to set the
