Facing linking error Error[Lp015]: section placement failure: overcommitted content in [0x2000'0020-0x2000'0028] while running x-cube-classb-v2-3-0 with IAR 8.40.1

[Anitha]

Hi Sir/Madam,

I'm trying to compile x-cube-classb-v2-3-0 STM32G081B_Eval project in IAR 8.40.1 but it giving below linker error.

Error[Lp015]: section placement failure: overcommitted content in [0x2000'0020-0x2000'0028] 

It is compiling fine with IAR 8.32.3 but with IAR 8.40.1 not working. STL 2.3.0 tested with IAR 8.32. I would like to know changes need to done in the STL testcase in order to work with IAR 8.40.1.

Please help to resolve this error?

Hi @Anitha​ ,

I was able to reproduce this error with IAR 8.40.2.

Thanks for bringing it to our attention, it is reported internally.

We will keep you informed if there is a workaround to apply on your side.

Hi Amel,

are there any updates about this topic? I am facing the same problem with IAR 8.40.3...

Hello @Anitha​  @Amel NASRI​  @ad'ag.1​ ,

Facing the same problem with IAR 8.40.1.

But there may be two solutions that I come up with.

1. Increase the region size (Added 8 byte more) and update the ending address from 0x2000'0028 to 0x2000'0030 for RUN_TIME_RAM_PNT_region. OR
2. Edit the __ICFEDIT_region_IRAM1_start__ to 0x2000'0030, so the RAM portion cannot be overlapped.

Both solutions compiled with zero errors. Is this the right solution for this problem? I go for the first one right now.

Also I've some doubt about the runtime partial RAM test:

Why this library test only the class-B RAM region for runtime RAM test? Why not full RAM? Is there a particular reason behind this?

-Thanks

Dear All,

Please note that the various STL packages are certified using the IDE versions as specified in table 3 of AN4435 (Guidelines for obtaining UL/CSA/IEC 60730-1/60335-1 Class B certification in any STM32 application).

In case there is any incompatibility issue, you need to refer to the Table 8. How to manage compatibility aspects and configure STL package.
