Regarding the SDK1.0.14.1081_hotfix_001, in order to add the patch, please follow the INSTALL.TXT. An sdk.diff file is also provided within the hotfix path.

Hello PM_Dialog,

Hello PM_Dialog,

I applied the patch.

Interestingly my project can't create the elf file afterwards with the same settings.

Building target: project.elf Invoking: Cross ARM C Linker c:/diasemi/smartsnippetsstudio1.6.7/gcc/4_9-2015q3/bin/../lib/gcc/arm-none-eabi/4.9.3/../../../../arm-none-eabi/bin/ld.exe: project.elf section `RETENTION_RAM0' will not fit in region `RetRAM0' c:/diasemi/smartsnippetsstudio1.6.7/gcc/4_9-2015q3/bin/../lib/gcc/arm-none-eabi/4.9.3/../../../../arm-none-eabi/bin/ld.exe: region `RetRAM0' overflowed by 1280 bytes collect2.exe: error: ld returned 1 exit status make: *** [project.elf] Error 1

Why is the hotfix changing the memory usage so much? Is this expected?

Best Regards,

Jens

Hi Jens,

Hi Jens,

Do you mean that with the same project you are getting this error when the patch is applied?

Have you done any other modifications? What is the device that you are using? DA14682 or DA14683?

The RETENTION_RAM0 collects all the zero-initialized data that should be placed in the retained RAM.

Thanks, PM_Dialog

Hi PM_Dialog,

Hi PM_Dialog,

Thanks for getting back to me.

Yes exactly the same project. I did not modify anything except the sdk patch and did a clean build afterwards.

It's a DA14683 device.

Best regards,

Jens

Hi jenswet,

Hi jenswet,

It is expected to have an increase of the memory usage due to the hotfix patch, because the code for the BLE is increased and some buffers for BLE too. That’s why you are getting this error with the same project. You must adjust the memory areas accordingly, increasing the RetRAM0 section.

Thanks, PM_Dialog
