Part Number: MSP432P401R
Tool/software: TI C/C++ Compiler
Hi TI forum community,
I get compiler warnings that the library call "sprintf" is power instensive and I should move the function to RAM.
The examples and links I've found in this forum about this topic refer to non-library, i.e. "my own code".
How do I add this, below, to a library call that takes parameters and returns a value?
__attribute__((ramfunc))
void f(void) { ... }
thanks,
bob s.
Both of the following links refer to ULP Advisor for MSP430, and not MSP432. But nearly all of the information applies to both devices.
Thanks and regards,
-George
robert schaefer said:Add the following lines to the linker command file
The linker command file is yet another source file in the project. It has a name similar to msp432p401r.cmd. This is the file you should modify.
For a general understanding of linker command files, please see the wiki article Linker Command File Primer.
Your linker command file will have a lines similar to ...
#ifdef __TI_COMPILER_VERSION__
#if __TI_COMPILER_VERSION__ >= 15009000
.TI.ramfunc : {} load=MAIN, run=SRAM_CODE, table(BINIT)
#endif
#endif
The #if lines check that the compiler version symbol is available, and the compiler version is greater than or equal to 15.9.0.LTS. Line 3 creates an output section named .TI.ramfunc. It is made up of all the input sections named .TI.ramfunc. This is the name of the section the compiler uses for functions marked with the ramfunc attribute. It allocated space in the MAIN memory range for loading, and in the SRAM_CODE memory range for running. An entry is made in the BINIT table. The BINIT table is processed by the system startup code. This processing copies this output section from the MAIN location to the SRAM_CODE location.
The next step is to make changes to this code so something similar to these lines occurs ...
robert schaefer said:.text:rts430.lib_printf : { rts*.lib<*printf.obj>(.text) } load = FLASH_EXECUTE, run = RAM_EXECUTE
This first change is only a intermediate step to the final solution. Change the .TI.ramfunc line to these lines ...
.TI.ramfunc :
{
*(.TI.ramfunc)
} load=MAIN, run=SRAM_CODE, table(BINIT)
This does exactly the same thing as before. The line *(.TI.ramfunc) says to collect all of the input sections with the name .TI.ramfunc. The purpose of this change is to create a spot in the syntax where we can add the entry for the library input sections. That looks like this ...
.TI.ramfunc :
{
--library=rts*.lib<*printf*.obj>(.text)
*(.TI.ramfunc)
} load=MAIN, run=SRAM_CODE, table(BINIT)
Line 3 is the addition. The --library option tells the linker to expect the input file not in the current directory, but among the directories listed with the --include_path (or -I) options. The syntax rts*.lib says to use whatever input file that starts with rts and ends with .lib. Look in the linker map file to see which RTS library is used. You will see something like rtsv7R4_T_be_eabi.lib. The syntax <*printf*.obj>(.text) says to use all the of the input sections named .text from files in the RTS library that have the name printf in them. One example is sprintf.obj.
Thanks and regards,
-George
Thank you.
I finally found the linker command file. Because I started my project with a copy of an example project it had the name of the original project - which has nothing to do with what I am doing now, so it was always there, I just disregarded it because I didn't know what that file was.
New problem, the linker dies on the snipped you gave me.
However, since I am using CCS twice, compiling at my desk on a mac, then recompiling on a Windows box to get to the target because only the windows box works with the XDS200 jtag debugger,
I have another .cmd file that I can look at. On the Windows box, the linker modification is:
#ifdef __TI_COMPILER_VERSION__
#if __TI_COMPILER_VERSION__ >= 15009000
ALIAS
{
SRAM_CODE (RWX): origin = 0x01000000
SRAM_DATA (RW) : origin = 0x20000000
} length = 0x00010000
#else
/* Hint: If the user wants to use ram functions, please observe that SRAM_CODE */
/* and SRAM_DATA memory areas are overlapping. You need to take measures to separate */
/* data from code in RAM. This is only valid for Compiler version earlier than 15.09.0.STS.*/
SRAM_CODE (RWX): origin = 0x01000000, length = 0x00010000
SRAM_DATA (RW) : origin = 0x20000000, length = 0x00010000
#endif
When I backfit the above lines to the mac version of CCS, the link succeeds. So then, the next step is to add:
.TI.ramfunc : {} load=MAIN, run=SRAM_CODE, table(BINIT)
However, I have no idea where to add the line. I put it above ALIAS and the link step fails. I put it after the "ALIAS {" and the link step fails. I put it after the end bracket } and the link step fails.
I would provide an error message but the error message changes depending on where I put the statement.
What should I try next?
I presumed your linker command file already had a line similar to
.TI.ramfunc : {} load=MAIN, run=SRAM_CODE, table(BINIT)
If that is not the case, then it does not make sense to use my changes as described.
Why did I presume that? When you start a new project in CCS, you indicate which device you use. Based on this choice, many details are automatically set. Among these is the linker command file. For ARM devices like MSP432, all the linker command files come from directory similar to ...
C:\ti\ccsv7\ccs_base\arm\include
I checked this directory and only found 2 linker command files for MSP432. Both of them had the same .TI.ramfunc line. Thus I presumed you linker command file has this line, and worked from there.
At this point, I'm not sure what linker command file you have, or how it should be changed. Please attach your original linker command file to your next post. Add the file extension .txt, or the forum will reject it.
Thanks and regards,
-George
Sorry for the late reply, for some reason I did not get an email after your response and got side-tracked last week.

The changes I recommend are in the linker command file I attach at the end of this post. While I cannot test these changes, I'm very confident it will work. Your main error is that you had a sections specification in the MEMORY directive.
An even better fix ... It appears you got this file from some TI software package. Update to the most recent version of that package, and use the linker command file found there.
Thanks and regards,
-George

The .binit output section contains the copy table that is processed to effect the copy of the .ramfuncs output section from the MAIN memory range to the SRAM_CODE memory range. This diagnostic ...
robert schaefer said:warning #10247-D: creating output section ".binit" without a SECTIONS specification
... means .binit is allocated in system memory without any guidance from you. Thus, it is probably allocated incorrectly.
When I look at similar linker command files for MSP432 devices, I see this line ...
.binit : > MAIN
So, try that first.
Thanks and regards,
-George
Please attach the linker map file you get after seeing the "no matching section" warning. As before, add the file extension .txt.

Sorry, but you sent the wrong file. You sent the linker command file. I need the linker map file. It is text file auto-generated by the linker, and has the file extension .map.

The map file has these lines in it ...
.TI.ramfunc
* 0 00008c50 00001170 RUN ADDR = 01000000
00008c50 00000060 rtsv7M4_T_le_v4SPD16_eabi.lib : sprintf.obj (.text)
00008cb0 00001110 : _printfi.obj (.text)
This says the .TI.ramfunc output section starts at load address 0x00008c50, and has a run address 0x01000000. It has only two input sections, which are those .text input sections from printf related functions in rtsv7M4_T_le_v4SPD16_eabi.lib.
You get the "no matching sections" warning because this line in your linker command file ...
*(.TI.ramfunc)
... corresponds to no input sections. You must not build with the option --ramfunc, or apply the ramfunc attribute to any functions. Both of those features are described in the ARM compiler manual. Search for ramfunc to find the details. If you intend for none your functions to be in RAM, then you can ignore the warning.
Thanks and regards,

Hi George,
Now I'm more confused than when I started.
Let me start from the beginning.
When I compile, I get the warning: "Detected sprintf() operation(s). Recommend moving them to RAM during run time or not using as these are processing/power intensive."
Please assume I have no clue, that even if there is an explanation in the compiler manual that I don't understand how to map the manual description to a CCS button-to-press.
But if I can find the --ramfunc switch somewhere in the CCS tool "properties" maze of abstruse features, then will ALL library functions will be moved into RAM, and I won't need to add additional statements to the linker command file?

What is your overall goal? That will help me understand what to focus on.
The overall goal of the ULP advice is help you reduce the power used by your system. It requires less power to execute out of SRAM than flash. Thus it makes sense to put the functions that use more cycles in SRAM. If your system calls sprintf, it is reasonable to assume that takes lots of cycles, and thus it makes sense to put that routine in SRAM.
Most of our discussion covered the details of how to get sprintf (and related functions) in SRAM. I suspect you may not be aware of this next part. The sprintf routine actually starts out in flash. During system startup, information in the .binit section is used to effect a copy from flash to SRAM. For the rest of system execution, sprintf is present in SRAM, as if it had been there all along.
The lines in your linker command file that arrange this are the following:
.TI.ramfunc :
{
--library=rts*.lib<*printf*.obj>(.text)
*(.TI.ramfunc)
} load=MAIN, run=SRAM_CODE, table(BINIT)
Line 1 names the output section .TI.ramfunc. Line 3 says to use as input sections all the the .text sections from files in the RTS library with printf in the file name. To be even more specific, this applies only to the printf functions in the RTS library your code actually calls. Line 4 says to include any input section that is named .TI.ramfunc. More on this later. Line 5 says to allocate this output section to the MAIN memory range for loading, allocate this output section to the SRAM_CODE memory range fo execution, and put an entry in the BINIT copy table. The BINIT copy table is automatically processed by the startup code to copy this output section from MAIN to SRAM_CODE. In this particular case, the table entry has the load address, run address, and length of the .TI.ramfunc output section. The location of the BINIT table entry is in a different output section named .binit. Though the names are similar, and they are related, please think of them as separate things. BINIT is a copy table, and .binit is the output section which contains it.
More on line 4 ... You might be confused that the output section is named .TI.ramfunc, and there are also input sections named .TI.ramfunc. It is OK to reuse section names like that. In fact, it is common. Even though the names are the same, don't lose the distinction between input sections and the output sections which contain them.
Yet more on line 4 ... You get a diagnostic "no matching section" about this line. You must have no input sections named .TI.ramfunc. There are two ways to get input sections named .TI.ramfunc. If you build with the option --ramfunc, then every function is in a .TI.ramfunc input section. Given that you have limited SRAM, this is probably not what you want. The other method is to apply the ramfunc function attribute.
__attribute__((ramfunc))
void function_name(void)
{
/* code here */
}
With this method, you can be selective about which functions go in SRAM. Whether to actually put any of your own functions in SRAM is up to you. If you decide no, then you can ignore the "no matching section" warning.
Thanks and regards,
-George
