nRF52 DK RAM for samples

kirkus

I am playing with the nRF52-DK preview and I noticed the samples in the 0.9 SDK are set to 32k of RAM. I increased it to 64k as per the chip specification and had no problems working with a large array, but was wondering if there was some limitation in the preview hardware or SDK that requires only using 32k?

    @Kirkus: The nRF52 preview chip has some anomaly from the production that we are going to release. You can have a look at the errata here. Issue #33 and #34 are related to your question. There are still 64kB of RAM on the nRF52 preview version, but they are located at 2 locations, each has 32kB. Please follow the information in the errata to declare correct IRAM1 and IRAM2 block.
