wolfssl-examples/RT1060

The examples for NXP i.MXRT1060 support the MMIMXRT1060-EVKB and the MMIMXRT1060-EVK boards.

Building and running the examples

Set up the NXP MCUXpresso SDK

• Use the NXP MCUXpresso SDK Builder available from NXP (https://mcuxpresso.nxp.com) to generate the SDK choosing:

  • Required Toolchains: GCC ARM Embedded

  For MIMXRT1060-EVKB:

  • Development Board: MIMXRT1060-EVKB (IMXRT1062xxxxA)
  • Version: 2.13.1

  For EVK-IMXRT1060:

  • Development Board: EVK-MIMXRT1060 (IMXRT1062xxxxA)
  • Version: 2.8.2

• Download the generated SDK archive and unpack it into:

  For MIMXRT1060-EVKB:

  • wolfssl-examples/RT1060/SDK_2_13_1_MIMXRT1060-EVKB

  For EVK-MIMXRT1060:

  • wolfssl-examples/RT1060/SDK_2_8_2_EVK-MIMXRT1060

Set up ARM cross-compilation tools

• Ensure that a recent arm-gcc toolchain is installed and reachable via the CC environment variable.

  • A recent toolchain can be obtained from ARM (https://developer.arm.com)

  • Example: CC=arm-none-eabi-gcc

Set up wolfSSL

• In the same directory as wolfssl-examples (i.e. the parent directory):

$ git clone git@github.com:wolfssl/wolfssl.git

Build wolfSSL

• In the wolfssl-examples/RT1060 directory:

  • For MIMXRT1060-EVKB:

$ SDK=SDK_2_13_1_MIMXRT1060-EVKB make

• For EVK-MIMXRT106:

$ SDK=SDK_2_8_2_EVK-MIMXRT1060 make

The resulting binary files will be in wolfssl-examples/RT1060:

• wolfcrypt-test.bin - wolfCrypt crytography test

• wolfcrypt-benchmark.bin - wolfCrypt cryptography benchmark

Download and run the built wolfSSL examples

• Connect the board to the host computer via the debug port

• Copy a wolfSSL example binary file to the storage device associated with the board

• Wait for the board to flash the image and reset

• Open a terminal console emulator and connect it to the port associated with the board, e.g. /dev/ttyACM0

• Reset the board. The wolfSSL example output will display in the terminal console

Notes

• EVK-MIMXRT1060 benchmark results are also available in the file results.md
