Hi,

As I didn't get any further responses from the customer, I typically assume that they've figured it out. Are you struggling with the exact same issue? Feel free to open a DZ ticket yourself, or expand on your situation here.

Also have a look at the question I sent out earlier here:

[quote user="Elfving"]

Have you made both the sw and hw changes needed? And was this a soft or hard reset?

[/quote]

In order for the approtect to take effect you need to both set it the right way, and have the right reset.

Regards,

Elfving

Hello, has your question been resolved? I also encountered this problem in the development process. Do you have any reference for me?

You may need a full power cycle instead of a soft reset, and double-check any required hardware settings - APPPROTECT often won’t take effect with software changes alone.

Hello, and thanks for the patience,
