https://devzone.nordicsemi.com/f/nordic-q-a/2296/sd_flash_page_erase-failing-with-s120Hey. Hope this was not asked before. At least I did not find it. I&#39;m trying the ble_app_hrs_c on s120. Got it to build with gcc (d&#39;oh) and got the serial logging to work. Now the problem is, sd_flash_page_erase() from pstorage_init() returns 0x0000000fen-USTelligent Community 13Mon, 25 Aug 2014 08:29:57 GMThttps://devzone.nordicsemi.com/thread/9540?ContentTypeID=1Mon, 25 Aug 2014 08:29:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:af7d42d1-c476-4c94-a0fd-3aaee4e61a33Leo Fu<p>I just have the same problem!</p><div style="clear:both;"></div>
