Installing ModusToolbox for First Use

Download the ModusToolbox™ Software for Linux (tested on version 3.0.0.9369 and 3.1.0.12257) to your host and unpack it:

# Set the MTB version. Option 1:
$ export MTB_VERSION_FULL=3.1.0.12257
$ export MTB_VERSION_SHORT=3.1

# Option 2:
$ export MTB_VERSION_FULL=3.0.0.9369
$ export MTB_VERSION_SHORT=3.0

$ cd ~
$ tar -C $HOME -xzf ModusToolbox_${MTB_VERSION_FULL}-linux-install.tar.gz

Set the environment variables:

$ export PATH=${HOME}/ModusToolbox/tools_${MTB_VERSION_SHORT}/project-creator/bin:$PATH
$ export CY_TOOLS_PATHS=${HOME}/ModusToolbox/tools_${MTB_VERSION_SHORT}

Install packages:

$ sudo apt update
$ sudo apt -y install libglib2.0-0 libgl1 make git ttylog

$ ${CY_TOOLS_PATHS}/modus-shell/postinstall

In addition, if you plan to run the project on the Eclipse IDE instead of just using the CLI:

$ sudo apt -y install libxcb-xinerama0 libncurses5

$ ${CY_TOOLS_PATHS}/openocd/udev_rules/install_rules.sh
$ ${CY_TOOLS_PATHS}/driver_media/install_rules.sh
$ ${CY_TOOLS_PATHS}/fw-loader/udev_rules/install_rules.sh
$ ${CY_TOOLS_PATHS}/modus-shell/postinstall

# Launch the IDE and import the project by: Quick Panel > Import Existing Application In-Place
$ ~/ModusToolbox/ide_3.1/eclipse/modustoolbox-eclipse

Initialize the mtb-example-wifi-mqtt-client project:

$ mkdir ~/mtb_projects
$ project-creator-cli \
    --board-uri https://github.com/cypresssemiconductorco/TARGET_CY8CPROTO-062-4343W \
    --board-id CY8CPROTO-062-4343W \
    --board-commit release-v4.1.0 \
    --app-uri https://github.com/Infineon/mtb-example-wifi-mqtt-client \
    --app-id mtb-example-wifi-mqtt-client \
    --app-commit release-v5.1.0 \
    --user-app-name mtb_example_wifi_mqtt_client \
    --target-dir ~/mtb_projects

Test build the project:

$ cd ~/mtb_projects/mtb_example_wifi_mqtt_client
$ make build -j$(nproc)

Program the application artifact onto the board, and remember to connect your board to the host before proceeding:
```
$ make program
```

Connect to the serial port to view the debug messages:

# Look for the serial port, e.g., /dev/ttyACM0
$ dmesg | grep tty

# Reading from the serial port
$ sudo ttylog -b 115200 -d /dev/ttyACM0

Cross-compile TPM2-TSS for PSoC 6

Install packages:

$ sudo apt update
$ sudo apt -y install autoconf-archive libcmocka0 libcmocka-dev procps iproute2 build-essential git \
    pkg-config gcc libtool automake libssl-dev uthash-dev autoconf doxygen libjson-c-dev \
    libini-config-dev libcurl4-openssl-dev uuid-dev pandoc acl libglib2.0-dev xxd jq

Set the environment variables:

$ export PATH=${HOME}/ModusToolbox/tools_${MTB_VERSION_SHORT}/gcc/bin:$PATH

Download tpm2-tss and its dependencies:

$ git clone https://github.com/tpm2-software/tpm2-tss ~/tpm2-tss
$ cd ~/tpm2-tss
$ git checkout d0632dabe8557754705f8d38ffffdafc9f4865d1

$ git clone https://github.com/infineon/psoc6-aws-iot-optiga-tpm ~/psoc6-aws-iot-optiga-tpm

Extract the compilation flags from the MTB project:

# Extract the raw compilation flags from the MTB project.
$ mtb_command=$(jq '.[] | select(.file == "source/main.c") | .command' $HOME/mtb_projects/mtb_example_wifi_mqtt_client/build/compile_commands.json)

# Trim the beginning and the end.
$ mtb_command_trimmed_head=$(echo $mtb_command | sed "s/.*-c //")
$ mtb_command_trimmed_tail=$(echo $mtb_command_trimmed_head | sed "s/ -o.*//")

# Remove single quotes and escape characters.
$ mtb_command_cleaned_quote=$(echo $mtb_command_trimmed_tail | sed "s/'\\\\\\\"/\\\"/")
$ mtb_command_cleaned_quote=$(echo $mtb_command_cleaned_quote | sed "s/\\\\\\\"'/\\\"/")

# Update the path.
$ compiler_flags=$(echo $mtb_command_cleaned_quote | sed "s#-I\.\.#-I$HOME/mtb_projects#g" | sed "s#-I\.#-I$HOME/mtb_projects/mtb_example_wifi_mqtt_client#g" | sed "s#-Ibsps#-I$HOME/mtb_projects/mtb_example_wifi_mqtt_client/bsps#g")

# Modify and add compilation flags.
$ compiler_flags=$(echo $compiler_flags | sed "s/nano\.specs/nosys\.specs/")
$ compiler_flags=$(echo $compiler_flags | sed "s/\(-pipe\)/\1 -fno-pie/")

$ echo $compiler_flags

Cross-compile:

$ ./bootstrap
$ ./configure --host=arm-none-eabi \
  --with-crypto=mbed \
  --enable-nodl --with-maxloglevel=none --disable-util-io --disable-tcti-device \
  --disable-tcti-mssim --disable-tcti-swtpm --disable-tcti-pcap \
  --disable-tcti-spi-ftdi --disable-tcti-spi-ltt2go --disable-tcti-i2c-ftdi \
  --disable-tcti-libtpms --disable-tcti-cmd --disable-fapi --disable-policy \
  CFLAGS="-DPATH_MAX=256 -DTSS2_TCTI_SUPPRESS_POLL_WARNINGS $compiler_flags"

# Overwrite the CFLAGS to modify the value of MEDTLS_USER_CONFIG_FILE to include escape characters.
# We are doing this here because autoconf does not accept escape characters.
$ compiler_flags="-DPATH_MAX=256 -DTSS2_TCTI_SUPPRESS_POLL_WARNINGS \
  $(echo $compiler_flags | sed 's/\"mbedtls_user_config.h\"/\\\"mbedtls_user_config.h\\\"/')"

$ make CFLAGS="$compiler_flags" -j$(nproc)

Install the resulting libraries in the /tmp/tpm2-tss directory:

$ mkdir /tmp/tpm2-tss
$ make DESTDIR=/tmp/tpm2-tss install -j$(nproc)

Add TPM2-TSS Libraries to the MTB Project

What's currently absent from the TSS library is the platform-specific TCTI module (Tss2_Tcti_Spi_Psoc6_Init(...)). Once this module is implemented in MTB, the TSS library will have the capability to access the PSoC 6 SPI interface for communication with the TPM.

The following steps describe how to add TSS libraries to your MTB project:

Copy the platform-specific TCTI implementation into your MTB project by:

$ cp ~/psoc6-aws-iot-optiga-tpm/src/tcti_spi_psoc6.* ~/mtb_projects/mtb_example_wifi_mqtt_client/source/

Include the TSS libraries in the build by modifying the MTB Makefile:

$ line=`awk '/^INCLUDES/ {c++} c==1{ print NR+1; exit }' ~/mtb_projects/mtb_example_wifi_mqtt_client/Makefile`
$ sed -i ${line}'i INCLUDES+=/tmp/tpm2-tss/usr/local/include' ~/mtb_projects/mtb_example_wifi_mqtt_client/Makefile

$ line=`awk '/^LDLIBS/ {c++} c==1{ print NR+1; exit }' ~/mtb_projects/mtb_example_wifi_mqtt_client/Makefile`
$ sed -i ${line}'i LDLIBS+=/tmp/tpm2-tss/usr/local/lib/libtss2-mu.a /tmp/tpm2-tss/usr/local/lib/libtss2-rc.a /tmp/tpm2-tss/usr/local/lib/libtss2-sys.a /tmp/tpm2-tss/usr/local/lib/libtss2-esys.a /tmp/tpm2-tss/usr/local/lib/libtss2-tctildr.a /tmp/tpm2-tss/usr/local/lib/libtss2-tcti-spi-helper.a' ~/mtb_projects/mtb_example_wifi_mqtt_client/Makefile

Copy the code along with the examples into your MTB project by:

$ cp ~/psoc6-aws-iot-optiga-tpm/src/tss2_* ~/mtb_projects/mtb_example_wifi_mqtt_client/source/

Rebuild the project:

$ cd ~/mtb_projects/mtb_example_wifi_mqtt_client
$ make clean
$ make build -j$(nproc)

Example Applications

Once the TSS libraries are ready for use, they can be tested with some examples:

$ sed -i ${line}'i\\n    snippet_1();\n    snippet_2();' ~/mtb_projects/mtb_example_wifi_mqtt_client/source/main.c

Rebuild the project:

$ cd ~/mtb_projects/mtb_example_wifi_mqtt_client
$ make clean
$ make build -j$(nproc)

Mbed TLS Examples

To run the Mbed TLS examples on the MTB project, some features of the Mbed TLS library, which are disabled by default, need to be enabled:

$ cp ~/mtb_projects/mtb_example_wifi_mqtt_client/configs/mbedtls_user_config.h ~/mtb_projects/mtb_example_wifi_mqtt_client/configs/mbedtls_user_config.h.bkup
$ sed -i 's/#undef MBEDTLS_X509_CSR_WRITE_C//g' ~/mtb_projects/mtb_example_wifi_mqtt_client/configs/mbedtls_user_config.h
$ sed -i 's/#undef MBEDTLS_X509_CRT_WRITE_C//g' ~/mtb_projects/mtb_example_wifi_mqtt_client/configs/mbedtls_user_config.h
$ sed -i 's/#undef MBEDTLS_X509_CREATE_C//g' ~/mtb_projects/mtb_example_wifi_mqtt_client/configs/mbedtls_user_config.h
$ sed -i 's/#undef MBEDTLS_X509_CSR_PARSE_C//g' ~/mtb_projects/mtb_example_wifi_mqtt_client/configs/mbedtls_user_config.h

Copy the code along with the examples into your MTB project by:

$ cp ~/psoc6-aws-iot-optiga-tpm/src/mbedtls_* ~/mtb_projects/mtb_example_wifi_mqtt_client/source/

Add the following code snippets to the main.c file in the MTB project. However, hold on! Scripts are provided below to automate the copying of code for your convenience.:

#include "mbedtls_examples.h"

void snippet_1()
{
    mbedtls_examples();
}

Here is a script for automating the copying of the code snippets:

$ cd ~/psoc6-aws-iot-optiga-tpm
$ sed -n $(expr `awk '/\`\`\`snippet2/{c++} c==1{ print NR; exit }' README.md` + 1)',$p' README.md > .README.md.tmp

$ sed -i ${line}'i\\n    snippet_1();' ~/mtb_projects/mtb_example_wifi_mqtt_client/source/main.c

Rebuild the project:

$ cd ~/mtb_projects/mtb_example_wifi_mqtt_client
$ make clean
$ make build -j$(nproc)

TPM-based Device Onboarding to AWS IoT Core

Based on what you have learned from the Mbed TLS examples, you can now prepare the MTB project for device onboarding to AWS IoT Core:

Provision the TPM with the desired key. For your convenience, you can reuse the project from the "Mbed TLS Examples" section and make modifications to the ~/mtb_projects/mtb_example_wifi_mqtt_client/source/mbedtls_examples.c file.
```
int mbedtls_examples()
{
    if (rsa(true)) {
        return 1;
    }

    return 0;
}
```
Capture the Certificate Signing Request (CSR) printed on the serial port. Create a file at ~/psoc6-aws-iot-optiga-tpm/aws-iot-core/out/tpm.csr and store the CSR within it.
```
-----BEGIN CERTIFICATE REQUEST-----
...
-----END CERTIFICATE REQUEST-----
```

Onboard the PSoC6 to AWS IoT Core by submitting the CSR and, in exchange, obtaining the AWS CA-signed client certificate. For your convenience:

# Install dependencies.
$ sudo apt install awscli curl

# Configure AWS account credentials and region.
$ aws configure

# Retrive the endpoint for later use.
$ aws iot describe-endpoint --endpoint-type iot:Data-ATS

# Create a thing in AWS IoT Core.
# The CSR will be sent to AWS, and in return, you will receive
# the client certificate (tpm.crt). Additionally, the script will
# fetch the AWS CA certificate for you. You will find all the certificates
# in ~/psoc6-aws-iot-optiga-tpm/aws-iot-core/out.
$ cd ~/psoc6-aws-iot-optiga-tpm/aws-iot-core
$ ./1_create_thing.sh

# Convert the certificates to C code format for later use.
$ ./2_pem_to_clang.sh

Instead of using a software key, modify the code to accept the TPM-based mbedtls_pk_context key object. The file to be modified is ~/mtb_projects/mtb_shared/secure-sockets/release-v3.3.0/source/COMPONENT_MBEDTLS/cy_tls.c; look for mbedtls_pk_init(...). The initialization of the key object can be found in the provided Mbed TLS examples. For your convenience, you may use the following snippet:

/* load key */
#if 0
mbedtls_pk_init( &identity->private_key );

ret = mbedtls_pk_parse_key( &identity->private_key, (const unsigned char *) private_key, private_key_len+1, NULL, 0 );
if ( ret != 0 )
{
    tls_cy_log_msg(CYLF_MIDDLEWARE, CY_LOG_ERR, "mbedtls_pk_parse_key failed with error %d\r\n", ret);
    result = CY_RSLT_MODULE_TLS_PARSE_KEY;
}
#endif

#include "mbedtls_tpm_pk.h"

ESYS_CONTEXT *esys_ctx;
mbedtls_tpm_rsa_context *tpm_rsa_ctx;

tpm_open(&esys_ctx, NULL);

mbedtls_pk_init(&identity->private_key);
mbedtls_pk_setup(&identity->private_key, &tpm_rsa_pkcs_v15_info);

tpm_rsa_ctx = (mbedtls_tpm_rsa_context *)identity->private_key.pk_ctx;
tpm_rsa_init(tpm_rsa_ctx, true, esys_ctx);

Configure the WiFi connection in ~/mtb_projects/mtb_example_wifi_mqtt_client/configs/wifi_config.h.
Lastly, configure the MQTT connection in ~/mtb_projects/mtb_example_wifi_mqtt_client/configs/mqtt_client_config.h:
- MQTT_BROKER_ADDRESS: The endpoint address from step 3.
- MQTT_PORT: 8883
- MQTT_SECURE_CONNECTION: 1
- CLIENT_CERTIFICATE: The client certificate from step 3.
- ROOT_CA_CERTIFICATE: The AWS CA certificate from step 3.

When you have finished testing, remove the thing from AWS IoT Core:

$ cd ~/psoc6-aws-iot-optiga-tpm/aws-iot-core
$ ./3_clean_thing.sh
