Firmware Updates

Scripts and bootloader

These are only required when using the "Script" method of updating the firmware. If you're using the GUI tool, you don't need these.

Download scripts and bootloader

Firmware downloads

When using the "MCUXpresso Secure Provisioning Tool" tool to update the firmware, download the "package" version of the firmware. For the script method, download the "hex" version.

The "v9", "v10" etc. after "package" indicates the version of the MCUXpresso Secure Provisioning Tool for which the package was prepared. Please be sure to use the right tool version for the firmware you're wanting to install.
