Hi,Elfving

Thank you for notifying me.
Understood. I will use v3.1.0 when developing with TFM.

best regards,

Hiroki

Hi again guys, Denghongyan H-ogawa

There seems to be a bug in TFM in this NCS version, and we can not connect to the Apple ecosystem because of it.

Unfortunately, it is hard to provide a simple workaround or fix for NCS 2.9, because there were many changes in our security modules. What I can suggest is to update to NCS 3.1.0 once it is released, to use it with the Apple ecosystem. There were some updates for in NCS recently, and we checked that NCS 3.1.0 should be ready to be used in the Apple ecosystem - Everything works properly on NCS 3.1.0-RC2.

Regards,

Elfving

Does this mean that it's currently impossible to release a product with TFM for Matter?

[/quote]

No that just means that it hasn't gone through production testing. We're expecting it to work, though it hasn't been tested in any rigorous way, so there might be some bugs and high power draws that haven't been noticed before.

Also, when do you plan to resolve this bug?

We are looking into fixing it, though it is hard to give you a timeframe for when it will be solved. If this is urgent for you, please contact your local regional sales manager, who might be able to speed things up (or let me know if you need his contact details).

Hi,Elfving

I understood that it's experimental.

I see. Thanks guys!

This does look like a bug. We are looking into it.

Please note though that TF-M for the nRF54L15 is currently experimental.

Hi,Elfving

I checked with addr2line.

Setting up addr2line on Windows takes some time, so I checked the elf address on Linux.
The result is below.

devzone.nordicsemi.com/.../lock_5F00_elf_5F00_addr2line.txt

This is occurring in the same file as denghongyan.
I think the address is different because denghongyan is doing it in the template sample code.

Hiroki

Hi EIfving,

I build a pure verison, just prj.conf add rtt log:

here is my commissiong log txt:

devzone.nordicsemi.com/.../commissioning_5F00_log.txthere is the error address to line:

Denghongyan — Thu, 03 Jul 2025 08:01:06 GMT

Yeah, for addr2line, I opened some log, if not, cannot use addr2lie:

here is my prj_conf:

Did you use a DK for this denghongyan?

here is my log and addr-line, I tested with default factory data:

I didn't change it because I wanted to verify the problem with the sample code base.

I confirmed this phenomenon in a custom product equipped with an nRF54l15 SoC. The custom product has the same external flash as the nrf54ldk, so the sample code works as is.

Could be worth checking both r15/pc and r14/l5. There are some guides in devacademy (here and here).[/quote]

I'll check it out, but I'm not sure if I'll get a reply right away.

1. Yes, I use nrf54l15DK physical board to do the test, and I only modified one place:

2. I will try, wait one moment.

3. I use NCS2.9.0

Hi guys,

Yes, it will definitely happen.

Thanks for chiming in Denghongyan! I guess this is more likely to be a bug of some sort when multiple people see it. Are you using the same NCS version, or a different one?

The version is 18.5 (22L572).Same version as Denghongyan.

Hi Hiroki and Elfving,

I got the same issue, my homepod mini version 18.5(22L572), this issue occurs every time during commission process.
My homepod mini can add other thread device successfully, and I have tried template demo with NRF54L15DK, got the same error log.

Hello Hiroki,

That sounds a bit odd.

What homepod version are you using?

Are you getting the same issue every time?

Elfving
