[ATTENTION REQUIRED] Manifest Tool being aware of Secure Partition enabled status when building

by Kevin Peng

Hi, I worked out a patch<https://review.trustedfirmware.org/c/TF-M/trusted-firmware-m/+/12025> to make the Manifest Tool (tfm_parse_manifest_list.py) aware of the Secure Partition status when building. Currently, the tool generates everything and then the Build System picks up the files needed. With the development of FF-M 1.1 feature, we need the tool to be aware of the Secure Partition enabled status to generate SPM configurations. The patch make use of the feature of CMake command configure_file which substitutes variable values referenced as @VAR@ or ${VAR}. It requires the "conditional" attributes in manifest lists to be surrounded by "@" for "${}". Then when you disable some Partition for building, the tool will not generate anything for that Partition such as PID/SID and TF-M Partition load info. So please out of tree Secure Partition manifest lists do the corresponding change to make the tool aware of that any Partitions are DISABLED. The tool currently only takes conditional value "OFF" or "FALSE" as Partitions being disabled, all other values are treated as enabled. This means if you do not make the change in the manifest list, the tool treats all the partitions as enabled always. Best Regards, Kevin

Musca B1 SE build broken?

PSoC64 TF-M - Port to CYB06447BZI-D54

by Cristiano Rodrigues

Hi guys, I am trying to put tf-m running in the PSoC64 board. However, I have a board that is slightly different from the one used by default in the tf-m. (I have *CYB06447BZI-D54* and the default tf-m is prepared to *CYS0644xxZI-S2D44). *For what I saw, the main difference among them is in memory, *CYB06447BZI-D54 *has 1MB of flash and 256kB of RAM and *CYS0644xxZI-S2D44 *has 2MB of Flash and 1MB of RAM. So now I'm trying to make a small port from tf-m to *CYB06447BZI-D54. * I changed the flash size in the flash_layout.h file to meet the *CYB06447BZI-D54 *flash size, however, I am having some difficulties in changing the RAM size. I am trying to change the RAM partitions size in region_defs.h and the smpu definitions of that partitions in smpu_config.h, but without much success. My question are: - Is possible to do the porting? Or does *CYB06447BZI-D54* not have enough memory to run tf-m? - If possible, what is I missing? Are more changes needed than I'm making? Best regards, Cristiano Rodrigues

Key derivation from HUK in NS application

by Kevin Townsend

Hi, I need to derive a new key from the HUK using HKDF, but are we able to request key derivation with the HUK from the NS side, or would we need to create a custom ARoT partittion for that? The requirements are identical to what PS does here with HKDF -- no salt and a fixed 'info' value, resulting in a key that is device-bound and can be regenerated at startup with no storage requirements: https://tf-m-user-guide.trustedfirmware.org/docs/technical_references/desig… (that API usage looks to be out of date, BTW, since "psa_open_key" now takes two params). I tried to do something similar from the NS side, modifying this code https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/tfm_integrat… ..., but get an error when trying to open the HUK with "TFM_CRYPTO_KEY_ID_HUK". That isn't surprising, but is there any alternative to generate keys from the HUK without a custom ARoT service? The fact that no storage is required when deriving from the HUK is significant. Best regards, Kevin

Using software random generator for FIH library

by Roman.Mazurak＠infineon.com

Hi all, Does anyone know if using software random generator seeded with TRNG to provide random delays for Fault Injection Hardening library is correct from PSA Level 3 certification point of view? The basic idea is to : 1. Use TRNG to provide seed for software random generator on fih_delay_init. 2. Use software random generator to implement fih_delay_random. 3. Periodically reseed software random generator with data from TRNG (optional). Thanks, Roman.

fce78aef breaks psoc64 console output with IARARM and ARMCLANG toolchain

by Thomas Törnblom

The current version breaks console output for the secure partition on psoc64 with IAR or ARMCLANG. Appears to work with GNUARM. It appears that this commit is the culprit: fce78aef Platform: Duplicate the tfm_hal_platform_init The console starts out good, then during tests only garbage is seen. Linker script issues? /Thomas -- *Thomas Törnblom*, /Product Engineer/ IAR Systems AB Box 23051, Strandbodgatan 1 SE-750 23 Uppsala, SWEDEN Mobile: +46 76 180 17 80 Fax: +46 18 16 78 01 E-mail: thomas.tornblom(a)iar.com Website: www.iar.com <http://www.iar.com> Twitter: www.twitter.com/iarsystems <http://www.twitter.com/iarsystems>
