MCX C: Using SEC Tool to Enter ISP Mode for Firmware Update
NXP officially launched the MCX C series chips in July 2024. As a Cortex-M0+ MCU with high cost-effectiveness, energy efficiency, and security, it strongly supports the upgrade of traditional 8-bit and 16-bit designs. Since its release, the chip has gained rapid favor among customers, with many projects now entering mass production.
In practical applications, more and more customers have inquired about how to enter the ISP mode of MCX C series chips and complete firmware updates. We have previously introduced the method using the blhost tool (see MCX C: How to Enter the ROM Bootloader to Update the Firmware - NXP Community). It is worth noting that the MCUXpresso Secure Provisioning (SEC) tool now supports MCX C series chips starting from version 25.03. The operation process is described in detail below.
Refer to the attached PDF file for details.
