Build project on Segger Embedded Studio always show more than 100% Ram usage

[leole]

Hi. I have a problem with Segger Embedded Studio. I always get more than 100% of RAM usage when building project on SES, even if examples projects from SDK . Anyone know what is the problem? I did not have any change on project configuration. I am using SES 5.34 64bit Window.

Hi,

Could you please upload your *.emProject project file and your flash_placement.xml file as well? You should obviously have gotten a linker error if the RAM usage exceeds 100 %, so I suspect the memory configuration must be wrong somewhere.

I have tried many examples on SDK (nRF5_SDK_14.2.0_17b948a) without any change in project configuration but all have the same problem. Please take a look at *emProject and flash_placement file and help me check if there is any wrong configuration.

Here is the example project that I am working on.

Sorry, I overlooked the fact that you experienced the same with other SDK examples as well. I assumed it only happened with your project at first, which is why I thought it had to be some project specific settings that were wrong.

Anyway. I was able to reproduce this now after updating from SES v5.32a to v5.34, and it appears to be caused by a bug in the "memory usage" viewer.

Notice how the stack_process section is shown to use 64K of RAM while it's actually zero bytes as shown in the *.map file:

A simple workaround I found for this was to place the .stack_process before the .stack section in the flash_placement.xml as shown below.

Nice! It works now. Thanks so much.
