Hi all,

I have a problem with a LPC824.

Somehow I cannot read nor write the SYSCON register. Both actions crash the controller. The GDB debugger log is in the code block below.

Do I have to enable that part of the APB somehow?

Thanks so much!

Ah I figured it out, I was mixing arm-elf with arm-eabi.

This can be closed.

So my question really is, is there a way you can prevent access to SYSCON?

If there isn't this uC is bricked, otherwise I'll have a lead to solving my problem.
