https://devzone.nordicsemi.com/f/nordic-q-a/7978/pstorage_register-called-twice-in-bootloaderThe bootloader in SDK 8.1.0 (at /nRF51_SDK_8.1.0 examples/dfu/bootloader) calls pstorate_register() twice. The first time as part of bootloader_init(), then on bootloader_dfu_start(). The first call works for me and the second call asserts.

You may need to update this also.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/28589?ContentTypeID=1Mon, 06 Jul 2015 12:40:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b71a3f4f-865b-4d79-b582-771d23e1fdabEliot Stock<p>That was it, thank you! PSTORAGE_MAX_APPLICATIONS was 1 in SDK 8.0.0 and I had ported my bootloader over from 8.0.0 without updating it to 2. The second call was going into the APP_ERROR_HANDLER().</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/28587?ContentTypeID=1Mon, 06 Jul 2015 09:24:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f8aeb74f-7cf4-4037-b9f9-27e2cc7b8e53Hung Bui<p>@Eliot Stock: I don&#39;t see any issue when calling pstorage_register twice. One is used for storing bootloader setting, and one is used for storing DFU image(s). Which issue do you have on the second call ? Have you made sure you set PSTORAGE_MAX_APPLICATIONS = 2 ?</p><div style="clear:both;"></div>
