Linker Script Changes Error in MCUxpresso 11.0.0

Hey Guys, 

I faced a huge problem while exporting my projects from version 10.3.1 to version 11.0.0. 

Importing went good but the Project would not build. Showcasing the error

PROGRAM_FLASH: 324296 B 472 KB 67.10%
SRAM_UPPER: 124092 B 65472 B 189.53%
SRAM_LOWER: 0 GB 65520 B 0.00%

c:/nxp/mcuxpressoide_11.0.0_2516/ide/plugins/com.nxp.mcuxpresso.tools.win32_11.0.0.201905131304/tools/bin/../lib/gcc/arm-none-eabi/8.2.1/../../../../arm-none-eabi/bin/ld.exe: region `SRAM_UPPER' overflowed by 58620 bytes

The project is a FreeRTOS project using the HEAP 5 memory scheme which has different memory location we can assign. 

Anyhow, the issue was that the auto-generated Linker File(*.ld file) was adding '.' at the end of the section names, you describe in the MCU settings as shown below 

VERSION 11.

.noinit_RAM2 (NOLOAD) :
{
. = ALIGN(4) ;
*(.noinit.$RAM2)
*(.noinit.$SRAM_LOWER)
*(.noinit.$RAM2.*)  
*(.noinit.$SRAM_LOWER.*)
. = ALIGN(4) ;
} > SRAM_LOWER

the same section in Version 10.3.1

.noinit_RAM2 (NOLOAD) : ALIGN(4)
{
*(.noinit.$RAM2*)
*(.noinit.$SRAM_LOWER*)
. = ALIGN(4) ;
} > SRAM_LOWER

The FreeRTOS heap5 file is where we mention the array size and name 

static __attribute__ ((used,section(".noinit.$SRAM_LOWER_Heap5"))) uint8_t heap_sram_lower[60*1024]; /* placed in in no_init section inside SRAM_LOWER */
static __attribute__ ((used,section(".noinit_Heap5"))) uint8_t heap_sram_upper[20*1024]; /* placed in in no_init section inside SRAM_UPPER */

These arrays where not being recognized by the linker and hence producing the overflowed error. 

Once I changed the name of the arrays to add '.' it fixed the problem. 

changed Named

static __attribute__ ((used,section(".noinit.$SRAM_LOWER._Heap5"))) uint8_t heap_sram_lower[63*1024]; /* placed in in no_init section inside SRAM_LOWER */
static __attribute__ ((used,section(".noinit_Heap5."))) uint8_t heap_sram_upper[28*1024]; /* placed in in no_init section inside SRAM_UPPER */

I don't know why that addition of character "." was added to the linker scripts. Slightly annoying when you are exporting to an updated version.

Please give a way to remove that feature for backward compatibility. So we don't have to make this small change on all the projects and branches of them.

The addition of the "." was one of the intentional changes made to the linker script system in MCUXpresso IDE v11.0.0 (these are mentioned inMCUXpresso IDE v11.0.0 Now Available ).

I'm sorry that in your case this triggered a problem - but certainly the "correct" fix for your specific case is to change your section attribute definition, as you have already found.

Regards,

It appears that the XText nature which was added to support freemarker syntax coloring does not handle comments in the link scripts gracefully.  I have migrated several LPCXpresso projects into MCUXpresso and found several of the internally generated linker stubs (where comments already exist) are not parsed by the freemarker xtext grammar properly.  Keep in mind these are comments which already existed in the default linker templates.  I did not add them.

The actual build generates binaries, but the project remains in an error state which undoubtedly WILL affect our automated build tools which rely on the command line compiler.  What do you propose as a fix for this problem?

After further experiments, I am reasonably certain that the xText parser for LD linker scripts is not working properly.  It appears that the parser gets hung up on wildcards in path names (because the syntax contains the multi-line comment sequence "/*".  The xtext parser obviously believes I have a multi-line comment starting on Lin 99.  The parser does not recover again until line 111, and then gets thrown off into another multi-line comment which continues on until line 122.

I like the idea of making the LD scripts more readable, but if you are only going to support a subset of the LD syntax, that's a non-starter in my opinion.  I used to write xText grammars and gave up on situations like this when the grammar attempted to implement an already-existing parsed language that is not actually implemented with xText under the hood in the GNU tools (in this example, LD).  There were just too many corner cases to be able to support, and there was no way to pull some of those cases off using what existed at the time with xText.  If you are making your own language from scratch, xText works very well.  Either way, I hope you are able to fix this problem, or have a workaround you can propose for us.

I attempted to remove the XText nature from my project, but no luck.  The project still has errors even though the output executables are generated and valid.

Does this help? https://community.nxp.com/thread/527820 

BTW: This is part of the Eclipse CDT project, and so you might get more help there.

That did the trick on my workstation.  I have yet to see if this will also work on our build server which invokes mcuxpresso (used to be lpcxpresso) from the command line.  I don't see it preserving the setting in the project file.  Thanks for the workaround!

Hi Brad,

>That did the trick on my workstation.

You mean changing the editor for the .ld files?

The linker script coloring is independent of the build system (it is for the editor view only), so should not affect your build.

As for the affected .ld files: would you mind posting them here? That way the IDE engineering team could check why parsing them failed (instead trying from your screenshots).

Yes Erich, I changed the editor for the *.ld files.  That's good news about the errors not affecting builds, although it is kind of annoying to have any errors exist in the project at all when nothing is problematic to the actual toolchains.  I hope you can fix it, but after working with Xtext in the past, I have my doubts.  Hopefully they have made some improvements to the framework.

Here is my linker script:

I think the simplest way for you to do this is to use the Managed Linker script scheme to override the default template provided in the IDE. Take a copy of

noinit_section.ldt (from C:\nxp\MCUXpressoIDE_11.0.0_2516\ide\Wizards\linker) and place it in a folder in your project called linkscripts

edit this file to remove the offending "."

You should now be ale to build as you expect. For info, see Chapter 18 in the User Guide.
