Hi Ken,
AFAIK current implementation of FWU partition also relies on shared data received from bootloader.

Hi,
Wondered if someone is expanding the boot data usage, as the default user is attestation only.
Please provide your case if you are expanding boot data usage.
Thanks!

Hi,
I'd like to give a brief introduction on the git normalization before merging this patch.
@Anton Komlev<mailto:Anton.Komlev@arm.com>, can I reserve 15-20 minutes of the next tech forum?

This patch was generated by git command automatically:
$ git add --renormalize .
It does change any contents of the files, except the line-endings in the repository.
Your existing local working tree should not be affected when you pick up it or later when it's merged.
The only file maintained manually is the .gitattributes

Subject: [TF-M] TF-M git repo normalization
Hi all,
Following the git normalization topic of the tech forum yesterday, I checked TF-M.
It has not been enabled the git normalization feature.
I've made a patch<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/8283> to make this happen.
Please check out or rebase your work upon this patch to see any issues.
Your existing working tree should not be affected regarding the line-endings.
What is the normalization?
To be simple, different developers on different Host OS can have different line-endings in their local working tree and do not need to worry about interference with each other.

Hi,
I have created a couple of patches to change the way to assemble the partitions, and start with the platform data:
https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/8288
The basic idea is we would avoid using pointer to link data between partitions, as mentioned in one of the past tech forum topics: https://www.trustedfirmware.org/docs/TF-M_partition_storage_arrangement.pdf
Please help to review this patch, especially the platform owners, as this change modifies almost all platform sources.
Also, I just use a direct 'find and replace' so some of the copyright years are not updated. Would update them in subsequent small patches.
Thanks.
/Ken
Hi all,

Hi,
Looks like we have an empty agenda for tomorrow's forum. Let's use the time for the free discussion on any TF-M topic. Please raise questions / issues / improvements worth to be discussed within the community.
See you,

Hi Thomas,
Sorry about that. I have reproduced the issue on AN521 by copying over the lpcxpresso55s69 storage config. I'll investigate a fix on that platform, but will need you to verify it for me afterwards as I don't have that platform.
Kind regards,
Jamie

I have just fixed an IAR linking issue for the nxp/lpcxpresso55s69, see https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/8251
I tried using the current sources, but it seems that there is some issues causing the board to run into a hard fault when built with GNUARM.
Not sure what commit caused the breakage.
Cheers,
Thomas
