Hi @joe1652
For the FRDM-MCXA153, we recommend starting with the official “Getting Started with FRDM-MCXA153” material, the board user manual, and the FRDM-MCXA153 SDK examples. The board includes an on-board MCU-Link debug probe, so you can program and debug the MCXA153 directly through the board’s debug USB connection.
As a first step, we suggest importing a simple SDK example such as hello_world or gpio_led_output, building it, flashing it through MCU-Link, and then starting a debug session to set breakpoints in main(). Once that flow is working, you can move on to peripheral examples such as UART, ADC, I2C, SPI, or timers.
If you still need any other material or help, please feel free to contact us.
