ARM cortex M0 design question

[mhanuel26]

Hi, I was able to port the C code to an Arm Cortex M0. The device does not have a Memory Protection Unit, I was trying to understand the implications for the deferencing issue on NULL pointers but as I am new to it and since library is meant to be used with M0 devices as well I want to check with you. Do you know how this will affect the scheuler and what issues I can expect?

Here is the section code I have commented.

I will appreciate your comments, Thank you,
