region `RAM' overflowed

[remtec]

In my application with nRF5340 and nrf connect sdk 2.3.0 which works well as Peripheral, if I activate CONFIG_DM_MODULE=y I always get the error "...ld.exe: region `RAM' overflowed by 9936 bytes ..."
What can I check to fix this problem?

Hi,

Thanks for checking with us. You cannot just enable one submodle and expect it to work, unless you know what you are doing. I suggest you play with Bluetooth: nRF Distance Measurement with Bluetooth LE discovery if you did not do.

For you questions related to `RAM' overflowed, what is your memory useage before adding CONFIG_DM_MODULE=y? Maybe there is not enough memory left for you to run dm submodule. I found following ticket may give you some hint about memory optimization.

I agree.
Wanting to try including the DM application in my project I started to see if there are any major space issues by including the DM module.
Thanks anyway for your help.

Just let me know if you need more help.

Best regards,
