No Break in Main()

[pyi285]

hi
I am a first-time technician using CodeWarrior.
I took a breakpoint while using this chip, but it doesn't stop at the point

The point part is the DisableWatchdog() in Main, and the pointer to the FMPLL_init() function.

Can you explain why it doesn't work?

 CodeWarrio is V11.0 But

When debugging with Flash, the brake works, but
When debugging with RAM, the brake does not work

 And if you turn off the power of the EVB board and turn it on again, all the firmware on the board disappears.

Do you know why?

Hi,

which version of CodeWarrior do you use?

Isn't that something similar to this topic?

And there's nice article from Erich Styger:

If you have RAM project then yes, it will disappear after power off-on sequence. But if you have flash project, it will definitely stay in flash. There's no reason for erase.
