https://devzone.nordicsemi.com/f/nordic-q-a/16990/reading-approtect-from-codeHi, I want to check if the FW is properly loaded into the chip and the chip is locked. Reading APPROTECT hangs the chip even if SD is not enabled. I assume APPROTECT is somehow protected from writing, but from reading??

I had wrong pointer casting and eventually was reading oustside the flash area or something like that. It was wierd since it caused hanging the chip not a hardfault nor wrong value... best regards</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65180?ContentTypeID=1Wed, 12 Oct 2016 12:37:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df4d7da0-a250-446d-854d-0b4073e85dfcSigurd<p>Can you provide the code you use to read the APPROTECT ?</p><div style="clear:both;"></div>
