How to sign images using ECDSA

[Hariprasath_K]

Hi,

We have purchased i.MXRT1170 EVK board and we are exploring how to sing the images using ECDSA p384 signature.
The i.MXRT1170 processor reference manual says that the MCU supports ECDSA p384 algorithm,

But we couldn't find this option in the NXP boot utility to sign the image using ECDSA. How can we enable/use ECDSA for signing the images?

Thank you,
Hari

Added to the above query,

If the NXP tools doesn't support ECDSA, any possible way for us to develop this feature ourselves?

When can we expect a version of NXP tool with this feature supported?

Hi @Hariprasath_K 

Thank you for your patience!

Currently our UI tools do not support the ECDSA sign. 

For this we will need to use the command line. I will write to you an email with some steps for this.

Best regards,

Diego
