Hi Vidar,

Are there any new possible workarounds for this 32k RAM limitation? I'm using PC10036 and am bumping into memory related errors while using S132 1.0.0-3 alpha (Error L6406E: No space in execution regions with .ANY selector matching...)

The other RAM block, located at 0x0800 0000, can be used, but the softdevice S132 alpha has a boundary check on the memory, and it will only accept memory from 0x20000000 area.

This is unfortunately an issue with the preview samples and the alpha version of the S132, and it will be fixed for the final product when that comes out, as this errata for the RAM location will then be fixed:

As of now, with the nRF52 preview kit, you can only use 32k of RAM when using the S132.

Sorry for the inconvenience.

Have your read these two erratas? infocenter.nordicsemi.com/index.jsp and infocenter.nordicsemi.com/index.jsp ?
