https://devzone.nordicsemi.com/f/nordic-q-a/5990/s110-8-0-0-dfu-example-on-nrf51822Hi, I am having problems using the the dfu_dual_bank_ble_s110_pca10028 example on a nrf51822_xxAA device. I have changed the memory ares to: IROM 1: 0x3C000, 0x3C00 IRAM 1: 0x20002C00, 0x1380 IRAM 2: 0x20003F80, 0x80 (NoInit) Altough i becomeen-USTelligent Community 13Thu, 24 Dec 2015 09:59:58 GMThttps://devzone.nordicsemi.com/thread/20903?ContentTypeID=1Thu, 24 Dec 2015 09:59:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:265efcfb-0411-4c59-b6ad-f53519ab03d6Hieu<p>Hi Mathias, I am having the same issue. Would you mind explain the reason behind adding #define PSTORAGE_RAW_MODE_ENABLE? I read the Raw Mode section <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk51.v10.0.0%2Flib_pstorage.html&amp;cp=4_0_1_3_17_3&amp;anchor=pstorage_raw_mode">here</a> but I still am not very clear on how Raw Mode helps. Also, are there any concerns when decreasing the Stack so much?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/20902?ContentTypeID=1Wed, 11 Mar 2015 15:55:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1e0a0a7f-a2a5-46f2-ad11-01bf91a1f622Mathias<p>I solved the problem myself by reducing the stack size to 255 in arm_startup_nrf51.s, hope this will be enough for the bootloader application but think so?</p> <p>Additionally I had to add:</p> <pre><code>#define PSTORAGE_RAW_MODE_ENABLE </code></pre> <p>in pstorage_platform.h.</p> <p>BR Mathias</p><div style="clear:both;"></div>
