TF-M Requirements

The following are some of the boards that can be used with TF-M:

Board	NSPE board name
ARM MPS2+ AN521	mps2_an521_ns (qemu supported)
ARM MPS3 AN547	mps3_an547_ns (qemu supported)
Laird Connectivity BL5340 DVK	bl5340_dvk_cpuapp_ns
NXP LPCXPRESSO55S69	lpcxpresso55s69_ns
nRF9160 DK	nrf9160dk_nrf9160_ns
nRF5340 DK	nrf5340dk_nrf5340_cpuapp_ns
ST B_U585I_IOT02A Discovery kit	b_u585i_iot02a_ns
ST Nucleo L552ZE Q	nucleo_l552ze_q_ns
ST STM32L562E-DK Discovery	stm32l562e_dk_ns
ARM V2M Musca B1	v2m_musca_b1_ns
ARM V2M Musca-S1	v2m_musca_s1_ns

You can run west boards -n _ns$ to search for non-secure variants of different board targets. To make sure TF-M is supported for a board in its output, check that CONFIG_TRUSTED_EXECUTION_NONSECURE is set to y in that board’s default configuration.

Software Requirements

The following Python modules are required when building TF-M binaries:

• cryptography

• pyasn1

• pyyaml

• cbor>=1.0.0

• imgtool>=1.9.0

• jinja2

• click

You can install them via:

$ pip3 install --user cryptography pyasn1 pyyaml cbor>=1.0.0 imgtool>=1.9.0 jinja2 click

They are used by TF-M’s signing utility to prepare firmware images for validation by the bootloader.

Part of the process of generating binaries for QEMU and merging signed secure and non-secure binaries on certain platforms also requires the use of the srec_cat utility.

This can be installed on Linux via:

$ sudo apt-get install srecord

And on OS X via:

$ brew install srecord

For Windows-based systems, please make sure you have a copy of the utility available on your system path. See, for example: SRecord for Windows
