MCUXPRESSO SECURE PROVISIONING TOOL是官方今年上半年推出的一个针对安全的软件工具，操作起来非常的简单便捷而且稳定可靠，对于安全功能不熟悉的用户十分友好。但就是目前功能还不是很完善，只能支持HAB的相关操作，后续像BEE之类的需等待更新。 详细的介绍信息以及用户手册请参考官方网址：MCUXpresso Secure Provisioning Tool | Software Development for NXP Microcontrollers (MCUs) | NXP | NXP  目前似乎知道这个工具的客户还不是很多，大部分用的更多的还是MCU BOOT UTILITY。那么如果已经用了MCU BOOT UTILITY烧录了FUSE，现在想用官方工具了怎么办了？其实对两者进行研究对比后，他们最原始的执行部分都是一样的，所以我们按照如下步骤进行相应的简单替换就能把新工具用起来： 首先是crts可keys的替换， MCU BOOT UTILITY的路径是在： ..\NXP-MCUBootUtility-2.2.0\NXP-MCUBootUtility-2.2.0\tools\cst MCUXPRESSO SECURE PROVISIONING的对应路径是在对应workspace的根目录： 另外还有一个就是encrypted模式会用到的hab_cert，需要将下面这两个文件对应替换，而且两个工具的命名不同，注意修改。 MCU BOOT UTILITY的路径是在： ..\NXP-MCUBootUtility-2.2.0\NXP-MCUBootUtility-2.2.0\gen\hab_cert MCUXPRESSO SECURE PROVISIONING的路径是workspace里： ..\secure_provisioning_RT1050\gen_hab_certs MCU BOOT UTILITY里命名为：SRK_1_2_3_4_table.bin; SRK_1_2_3_4_fuse.bin MCUXPRESSO SECURE PROVISIONING里命名为：SRK_fuses.bin; SRK_hash.bin 至此，就能够在新工具上用起来了 最后提一下，就是这个新工具是可以建不同的workspace来相应存储不同秘钥的项目，能够方便用户区分。在新工具下建的项目也是可以互相替换秘钥的，参考上术步骤中的secure provisioning部分即可。

Overview ======== The LPUART example for FreeRTOS demonstrates the possibility to use the LPUART driver in the RTOS with hardware flow control. The example uses two instances of LPUART IP and sends data between them. The UART signals must be jumpered together on the board. Toolchain supported =================== - MCUXpresso 11.0.0 Hardware requirements ===================== - Mini/micro USB cable - MIMXRT1050-EVKB board - Personal Computer Board settings ============== R278 and R279 must be populated, or have pads shorted. These resistors are under the display opposite side of board from uSD connector. The following pins need to be jumpered together: --------------------------------------------------------------------------------- | | UART3 (UARTA) | UART8 (UARTB) | |---|-------------------------------------|-------------------------------------| | # | Signal | Function | Jumper | Jumper | Function | Signal | |---|---------------|----------|----------|----------|----------|---------------| | 1 | GPIO_AD_B1_07 | RX | J22-pin1 | J23-pin1 | TX | GPIO_AD_B1_10 | | 2 | GPIO_AD_B1_06 | TX | J22-pin2 | J23-pin2 | RX | GPIO_AD_B1_11 | | 3 | GPIO_AD_B1_04 | CTS | J23-pin3 | J24-pin5 | RTS | GPIO_SD_B0_03 | | 4 | GPIO_AD_B1_05 | RTS | J23-pin4 | J24-pin4 | CTS | GPIO_SD_B0_02 | --------------------------------------------------------------------------------- Prepare the Demo ================ 1. Connect a USB cable between the host PC and the OpenSDA USB port on the target board. 2. Open a serial terminal with the following settings: - 115200 baud rate - 8 data bits - No parity - One stop bit - No flow control 3. Download the program to the target board. 4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo. Running the demo ================ You will see status of the example printed to the console.
