Source code: https://github.com/JayHeng/NXP-MCUBootUtility 【v1.3.0】 Features: > 1. Can generate .sb file by actions in efuse operation utility window >    支持生成仅含自定义efuse烧写操作(在efuse operation windows里指定)的.sb格式文件 Improvements: > 1. HAB signed mode should not appliable for FlexSPI/SEMC NOR device Non-XIP boot with RT1020/1015 ROM >    HAB签名模式在i.MXRT1020/1015下应不支持从FlexSPI NOR/SEMC NOR启动设备中Non-XIP启动 > 2. HAB encrypted mode should not appliable for FlexSPI/SEMC NOR device boot with RT1020/1015 ROM >    HAB加密模式在i.MXRT1020/1015下应不支持从FlexSPI NOR/SEMC NOR启动设备中启动 > 3. Multiple .sb files(all, flash, efuse) should be generated if there is efuse operation in all-in-one action >    当All-In-One操作中包含efuse烧写操作时，会生成3个.sb文件(全部操作、仅flash操作、仅efuse操作) > 4. Can generate .sb file without board connection when boot device type is NOR >    当启动设备是NOR型Flash时，可以不用连接板子直接生成.sb文件 > 5. Automatic image readback can be disabled to save operation time >    一键操作下的自动程序回读可以被禁掉，用以节省操作时间 > 6. The text of language option in menu bar should be static and easy understanding >    菜单栏里的语言选项标签应该是静态且易于理解的(中英双语同时显示) Bugfixes: > 1. Cannot generate bootable image when original image (hex/bin) size is larger than 64KB >    当输入的源image文件格式为hex或者bin且其大小超过64KB时，生成可启动程序会失败 > 2. Cannot download large image file (eg 6.8MB) in some case >    当输入的源image文件非常大时(比如6.8MB)，下载可能会超时失败 > 3. There is language switch issue with some dynamic labels >    当切换显示语言时，有一些控件标签(如Connect按钮)不能实时更新 > 4. Some led demos of RT1050 EVKB board are invalid >    /apps目录下RT1050 EVKB板子的一些LED demo是无效的 【v1.4.0】 Features: > 1. Support for loading bootable image into uSDHC SD/eMMC boot device >    支持下载Bootable image进主动启动设备 - uSDHC接口SD/eMMC卡 > 2. Provide friendly way to view and set mixed eFuse fields >    支持更直观友好的方式去查看/设置某些混合功能的eFuse区域 Improvements: > 1. Set default FlexSPI NOR device to align with NXP EVK boards >    默认FlexSPI NOR device应与恩智浦官方EVK板卡相匹配 > 2. Enable real-time gauge for Flash Programmer actions >    为通用Flash编程器里的操作添加实时进度条显示

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.
