Hello
I want to use Breakpoint in the source code.
I found the MRC and MCR approaches in the Achitecture documentation.
First, the user permissions were changed to previlage.
The problem is that an exception occurs when the CP14 register is accessed.
An exception also occurs when writing a value to DBGLAR. (__MCR(14, 0, 0xC5ACCE55, 7, 12, 6);)
How can I access the CP14 register?
And solved the problem.
But another problem arose.
I intentionally caused a prefetch exception. But The prefetch exception handler fails to execute and appears to be stuck in vector table prefetch.
And the other question is, when you get hit with bp, is there a way to find out which bp number I got hit with?Hi Changmin,

I don't know which IDE you are talking about, but if you are using CCS then you can easily identify the which breakpoint it hit with.
For example:
You can open BP window from below path.
Once you open it will show all the breakpoints that asserted.
If a breakpoint Hit, then it will highlight the corresponding breakpoint as below:
You can see a arrow break point under the corresponding breakpoint.
