How to change the top address of the app

No, it's not actually "closed" - you can still add comments.

However, it is best to stick to one question per thread - that makes it much easier for others searching for help!

If you want to cross-reference, you can always post links both here &in your new thread ...

Keep the content relevant to the title.

BTW: the idea is that you verify the answer(s) which resolved your question - not my post on how to do verify an answer!

You can verify more than 1 answer.

You can change your mind, and "un-verify" an answer.

Please tell me one more thing.
When "Verify" is selected, "CLOSED: ticket title" is notified in "Your Notifications".
When "Verify" is selected, will the ticket be closed?
I still want to ask questions.

I think I have already "Verify".
Do I need to "Verify" my remarks?
Or talk about other tickets?
I will check other tickets as well.

This problem has been resolved by calling "sd_softdevice_vector_table_base_set(0x30000)".
Thank you for answering.

I want to do DFU without using BootLoader.
I want Application-A to have the ability to rewrite Application-B.
Therefore, I want to manage the area separately for Application-A and Application-B.

I know that BootLoader can have DFU functionality.
However, I do not want to do DFU with BootLoader for various reasons.
Therefore, I am considering a method of doing DFU without using BootLoader.
As a way of doing that, I am thinking of dividing the area into Application-A and Application-B.

>> Could the Application-B work without Application-A?
No.
Application-A has the role of jumping to Application-B.
SoftDevice first executes Application-A.
Therefore, Application-B cannot work without Application-A.

Yes

Hi,

Could the Application-B work without Application-A?

Do you use the project for pca10040?

Again, what is your goal in doing that? What are you hoping to achieve by doing that?

Sorry, there was not enough explanation.
I want to split it into two applications.
Therefore, I have created two projects (Application-A and Application-B) and created the application separately.
I want to load Application-A and Application-B into their respective areas and run them as a single application.
Application-A uses the area from 0x26000 to 0x2FFFF.
Application-B uses the area from 0x30000 to 0x7FFFF.
* This thread is talking about Application-B.

SoftDevice first runs Application-A.
Application-A jumps to Application-B when certain conditions are met.
* Confirmed to jump to Application-B.
In that case, the above error occurred in Application-B.

Yes, related to this question.

Yes, that's right.

I'm sorry, I will also check other threads.

Hi,

[quote user=""]I want to change the top address of the app to 0x30000.[/quote]

Why do you want to change to 0x30000?

The application should start at the top of the SoftDevice. There cannot be a gap between them.

Surely, this is the bottom (ie, lowest) address of the app ?

If your app works with a SoftDevice, that needs to know the start address - you can't just arbitrarily move it!

Why do you want to do this anyhow?
