https://devzone.nordicsemi.com/f/nordic-q-a/7471/different-behaviour-with-different-dev-boardsHey everyone, I&#39;m getting a really weird error. I&#39;m using two dev boards for my application: a PCA10001 board (MBED enabled) and a PCA20006 beacon board with Segger&#39;s j-link debugger. I program the MBED board by compiling my code with make, mergingen-USTelligent Community 13Sat, 06 Jun 2015 19:28:21 GMThttps://devzone.nordicsemi.com/thread/26598?ContentTypeID=1Sat, 06 Jun 2015 19:28:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:97cd0ad6-6d51-4b57-a88a-74fbba9c7af4Susheel Nuguru<p>probably both has different RAM sizes, did you check if the latter board has program compiled with correct RAM size?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/26599?ContentTypeID=1Sat, 06 Jun 2015 13:02:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6df646e3-aaec-4d79-9495-0ca0c7e81ef4RK<p>No I have no ideas. However I assume both of them go through strtok() at some point early in the process, how about putting a breakpoint there to find out if the arguments are the same or different.</p> <p>What assembler is it actually executing, or just executed, when it goes to hardfault? strtok must be a pretty simple routine, only reads bytes you&#39;d think, so shouldn&#39;t be word alignment, I have to think you&#39;re reading memory at a very invalid location. Where does the string you are tokenizing come from?</p><div style="clear:both;"></div>
