Request for Old Version of Code Signing Tool (CST) for i.MX6Q HAB Development

Dear NXP Technical Support Team,

I am currently developing a High Assurance Boot (HAB) secure boot solution based on the ‌i.MX6Q SabreSD platform‌, using the official NXP BSP release L3.14.52_1.1.0 GA which is fully validated for our product.

The latest CST v3.1.0 downloaded from the official portal is not fully compatible with this legacy BSP version, and it cannot generate valid signature data that matches the HABv4 protocol of i.MX6Q. This blocks our subsequent secure boot verification work.

I have already read and accepted the NXP Software License Agreement for the Code Signing Tool, and I confirm that this tool will only be used for internal product development on our NXP i.MX series chips.

Could you please provide the download link for ‌CST v2.3.2 (for HABv4)‌? This version is the officially recommended matching tool for the i.MX6Q BSP we are using.

If you need any additional information about our project or chip part number, please feel free to contact me.

Thank you for your support.

Best regards,

lixuehui

Hello,

I’m working with an i.MX6Q SabreSD and the legacy L3.14.52_1.1.0 BSP, but CST v3.1.0 isn’t fully compatible. Any official download link or guidance would be greatly appreciated.

NXP’s current i.MX6Q software page lists CST 3.1.0 as the downloadable “i.MX High Assurance Boot Reference Code Signing Tool,” revision 3.1.0. fmc4me
