Thanks for your post. You can use blhost to program the firmware to MCX-C444. The blhost application is used on a host computer to issue commands to an NXP platform running an implementation of the Kinetis bootloader.

The download link of BLHOST: blhost . And the Kinetis blhost User's Guide can be seen here: KBLHOSTUG .

In addition to BLHOST, you can also utilize the flashing tool script developed based on the Secure Provisioning SDK (SPSDK). This script is capable of directly flash the image file into the Flash after the MCU enters the ROM bootloader. What's more, it integrates the API of BLHOST. For specific details, please refer to the official website of SPSDK.

Introduction — SPSDK documentation

Hope it can help you.

BRs,

Hi,
I know that we have MCUXPresso secure provisioning tool to program the MCX-C44X part,
Do we need to follow the any procedure to put device in bootloader mode or will MCUXPresso secure provisioning tool take care all those things?

Can you please help me on this?

Hello @shivajiyannaboina_tfs ,

For MCXC devices, the SEC tool can only perform operations after the device has already entered bootloader mode.
If you need to place the device into bootloader mode, the SEC tool is not able to perform this step.
Please refer to the links below for two methods to enter bootloader mode.

MCX C: How to Enter the ROM Bootloader to Update the Firmware

Using mass erase method is more recommended way.

Hope it helps.
