I am updating this thread to give you a script to update the flash_placement.xml to work with newer SES versions.

For example for updating the UART peripheral sample flash_placement file you just need to run something like this

python3 ses_unlimit_text_rodata.py examples/peripheral/uart/pca10100e/blank/ses/flash_placement.xml

If you want to do a dry run fist then you can do

python3 tools/ses_unlimit_text_rodata.py --dry-run examples/peripheral/uart/pca10100e/blank/ses/flash_placement.xml

This error typically means your code or constants exceed the allocated flash or RAM memory sizes in the linker script or SES configuration. Check and adjust the memory regions in your project's .ld file or in the SES flappy dunk project settings to match your microcontroller's specifications.

It looks like you're encountering memory allocation issues in your build of the "blinky" example. The errors suggest that the .text and .rodata sections are exceeding the allocated size. Try checking your linker script for memory size definitions or optimizing the bloxstrap code to fit within the specified memory limits.

.Earlier I was facing the same issue with version 7.92k but now my blinky code is getting compiled successfully on Segger embedded studio version 6.30 but jlink is connect getting connected it says failed to open DLL. My nrf7002 dk board is connected to my MacBook Pro M2 and it is receiving power but can't see the output of my code because of this issue

I imagine that it might have something to do with packing the data. Could it be that if you align everything on 4-byte boundaries, it uses too much padding? Just a thought.

I have the same issue with version 16.1.0 of the nRF5 SDK.

Hi,

You remove size="0x4" and it work because.

.text is related to the code size and .rodata is related to the constant data size.

So, when you put size="0x4", that mean you limit your code size to 4 bytes and limit your constant data to 4 bytes also.,

even a simple code like the blinky example. it take about 4Kbytes

So, If you need to set the size of this code, you have to set the size bigger than your code such as size="0x1000" (1024 * 4 = 4096 bytes, 4Kbytes). It will work.

A minor clarification...

Look in flash_placement.xml in the ses subdirectory.

You should see:

and

Remove: size="0x4" from both lines resulting in:

and

I have no idea why this works.

Hi,

I just reply to Steve.Klinkon. I think is similar question.

Hi,

I'm sorry, I never try SES 6.30 before. And I'm a new user for Segger and Nordic also.

I just would like to share what I understan.

if you look at the release notes from Segger:

https://studio.segger.com/index.htm?https://studio.segger.com/arm_segger_studio_release_notes.htm

From SES 6.30 to SES 6.32 they have some update about the Build. But I don't know what they did but it make some affect.

For what I understand, if you are using SDK_17.1.0, it should not work with SES 6.30 also because

"flash_placement.xml" is using for linking the project.

The 2 ProgramSections that I was mention:

and

if you look at the project opton

.text is the code section and .rodata is constan section.

both of them should not limit the size.

If you compare the flash_placement.xml between SDK_17.1.0 with all the older version SDK.

You will see no one limit the size for both of them. that why if you are using the older SDK, It will work.

I hope this is asnwer your question.

Regards,

Hello I faced the same problem as the op. So I have two questions:

Why SES 6.30 doesn't have this problem and SES 6.32 does.
In SES 6.32 works if we do what you suggested.. What are we doing and what does it affect the build system when we delete "sizeof="0x4" from the file.

Thanks

I'm experiencing the same issue with SES 6.32 and 6.32a.

Going back to 6.30 seems to compile the project OK.

Also, following steps from inw also works with SES 6.32. What are the consequences of deleting "sizeof="0x4" from "flash_placement.xml" and why does it solve the problem?

Thanks,

Steve

Hi,

Please look at the file "flash_placement.xml" in your project folder.

you shoule see:

and

Just delete "sizeof="0x4" from both of them then it should fix your problem.

Or you just go back to older SDK version such as 16.0.0

Noom.

Hello,

It's quite strange you are getting the error while building. Can you please uninstall Segger and try installing it again with version 6.30 and give it a try.

Kind Regards,
