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 Best Regards, Kevin From: TF-M <tf-m-bounces(a)lists.trustedfirmware.org> On Behalf Of Kevin Peng via TF-M Sent: Friday, February 5, 2021 9:53 AM To: tf-m(a)lists.trustedfirmware.org Cc: nd <nd(a)arm.com> 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.

Re: [TF-M] NXP lpcxpresso55s69 appears broken

by Jamie Fox

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.

Re: [TF-M] Fatal error handler in secure FW - review request

by Kevin Townsend

Oyvind, Thanks for putting this together. Looks quite useful, and saves some monotony debugging. I put together a similar script but as a Python function for GDB: https://gist.github.com/microbuilder/1677a27e4566a28b36a79f954f1dede6 ... having this in C, however, means you don't need to have a Python-enabled version of GDB.

Fatal error handler in secure FW - review request

by Rønningstad, Øyvind

Hi everyone I wanted to make it easier to debug HardFaults/BusFaults/SecureFaults in TFM, since I've gotten quite a few of them while adding the nrf platforms. I have created a proposal in https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/7891 and would like to get some comments on the general idea. The proposal gathers a number of different values, especially the ones that are harder to retrieve in a debugger, like the fault status registers in SCB. The values are placed in memory so they can be inspected in a debugger, and if built with -DTFM_SPM_LOG_LEVEL=TFM_SPM_LOG_LEVEL_DEBUG they are also printed. Here is an example of the printout: FATAL ERROR: HardFault Here is some context for the exception: EXC_RETURN (LR): 0xFFFFFFBD Exception came from non-secure FW in thread mode. MSP(_S): 0x200007F8 PSP(_S): 0x20000F28 Exception frame at: 0x200176D8 R0: 0x0000003E R1: 0x00000001 R2: 0x00000001 R3: 0xFFFFFFFF R12: 0x00000000 LR: 0x00050623 PC: 0x00050626 CFSR: 0x00000000 BFAR: Not Valid MMFAR: Not Valid HFSR: 0x40000000 SFSR: 0x00000000 SFAR: Not Valid BR, Øyvind Rønningstad
