BusPal Application for FRDM MCX Families

This project contains different folders, one for each supported BusPal device:

• FRDM-MCXW71
• FRDM-MCXA156

BusPal

Buspal acts as a bus translator with an established connection with blhost over UART and with the target device over I2C, SPI or CAN, and assists blhost in carrying out commands and responses from the USB target device.

This software pack provides the buspal application ported to different MCX device families, as an extension to the original BusPal application provided with the Kinetis Bootloader package, available only for selected platforms.

For more details on the BusPal software tool and the MCU bootloader for NXP MCUs, refer to the following link: https://www.nxp.com/design/design-center/software/development-software/mcuxpresso-software-and-tools-/mcu-bootloader-for-nxp-microcontrollers:MCUBOOT

Boards: FRDM-MCXW71, FRDM-MCXA156

Categories: Bridge, Tools

Peripherals: CAN, I2C, SPI, UART

Toolchains: MCUXpresso IDE

1. Software

This project was implemented using MCUXpresso IDE version 11.10.0, and the latest SDK for the selected board.

To communicate with BusPal device, SPSDK is used for I2C and SPI interfaces. To communicate via CAN, blhost needs to be used.

2. Hardware

Apart from the selected buspal board, this project uses the following hardware:

• Host Computer
• Target MCU: any NXP MCU with a flashloader / bootloader
