https://devzone.nordicsemi.com/f/nordic-q-a/11374/chip-hangs-on-flash-eraseI&#39;m using custom board with 32MHz oscillator and S110 SD 7.1 (SDK 6.1). Somteimes (quite rare) the chip completely hangs when calling sd_flash_erase in pstorage.c. Only hard reset recovers the chip. Do you have any idea what could cause this?en-USTelligent Community 13Wed, 20 Jan 2016 08:16:06 GMThttps://devzone.nordicsemi.com/thread/42859?ContentTypeID=1Wed, 20 Jan 2016 08:16:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c49b9d48-bb33-4665-955e-f196ac7abef2Susheel Nuguru<p>need to check your code, can you attach the project, i can try it on my desk. If you are uncomfortable putting code in public, then send me it as an attachment in PVT message.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/42860?ContentTypeID=1Tue, 19 Jan 2016 16:41:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d96e8d8e-b9bf-4233-b714-ae2f008e3432Cyril Hruscak<p>Sorry for not being clear. The APP_ERROR_CHECK is never reached. The function never returns.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/42858?ContentTypeID=1Mon, 18 Jan 2016 09:55:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f412b28-5235-4434-b615-6fb0accf8e84Susheel Nuguru<p>What do you mean by hangs? it could be simple APP_ERROR_CHECK fail case. Did you try to debug it and pinpoint exactly where it happens?</p><div style="clear:both;"></div>
