gPTP sample does not boot with NUCLEO-H563ZI

[DBS06]

Describe the bug

Hello,

currently I am testing gPTP with samples/net/gptp with the STM32 NUCLEO-H563ZI Board.
With Zephyr 4.1 the board does boot up and prints out on the console, with Zephyr 4.2 it does not boot up.

Regression

• This is a regression.

Steps to reproduce

Steps to reproduce with 4.1.0:

1. git checkout v4.1.0
2. west update
3. west packages pip --install
4. west build -p always -b nucleo_h563zi/stm32h563xx samples/net/gptp
5. west flash

Impact

Showstopper – Prevents release or major functionality; system unusable.

Environment

• OS: Debian 13
• Toolchain: zephyr sdk 0.17.0 and 0.17.4
• Version 4.1.0 and 4.2.0
• STM32 NUCLEO-H563ZI Board

Hi @DBS06,

Thanks for your report. Could you git bisect the issue to find which commit introduce the regression?
That would be great!

[DBS06]

@ljd42 Hi, I did the git bisect and identified this as the first bad commit: 18277b4

FYI:
I used solely the zephyr sdk 0.17.0 and for testing I did

west update && \
west zephyr-export && \
west packages pip --install && \
west build -p always -b nucleo_h563zi/stm32h563xx samples/net/gptp && \
west flash

[ljd42]

@DBS06 : thank you so much testing further! This will greatly ease debugging the issue.

Hello @DBS06 it seems that this bug has been fixed thanks to this commit: ca6e25a

As you mentionned, this commit: 18277b4 caused Zephyr to get stuck during boot because it moved the hal_init_v2 from the Ethernet initialization to the iface init. The issue was that the iface initialization happens after the PTP initialization and because of that we get stuck when trying to configure PTP.

This commit: ca6e25a puts it back in the Ethernet initialization which is before the PTP initialization, and as a result, it now boots fine on my side.

Could you check if it boots on your side aswell?

@juickar thanks a lot for the information!

I will try it on Monday, when I am back at work and have my board again.

[DBS06]

@juickar works again with the recent changes, thanks a lot!
