hello ! in fact i want to place 2 section with overlay technique on a CORTEX M0 but always i face a hardfault , please is there any tricks on how i should use the overlay manager or what
So you first need to determine why, exactly, you are getting the Hard Fault.
Google, "Cortex M0 Hard Fault" for plenty of tips & tutorials on debugging Cortex-M0 Hard Faults.
You should also study a copy of Joseph Yiu's "The Definitive Guide to ARM® Cortex®-M0 and Cortex-M0+ Processors"

thank you sir for your reply , in fact i adapted my cortex M0 hard fault handler to see the register just like on cortex M3 and that hard fault is caused by the wrong use of overlay technique so i want to know is there any tricks to add to overlay manager to resolve this
