LX2160ardb_rev2: ECC/ECDSA verification in u-boot without using SEC engine

[csr202]

LX2160ardb_rev2:

Does u-boot support ECC/ECDSA verification without using hw SEC engine?

Is there any existing implementation available in u-boot (e.g. open-ssl) for ECC/ECDSA verification without using hw SEC engine?  

[csr202]

any update on this thread ?

Just found another opensource patches raised to support image signing with ECSDA: https://lists.denx.de/pipermail/u-boot/2021-January/436864.html
customer may try it themselves.
Again, not supported or tested by NXP.

Thanks for the prompt response.

Let me confirm with the AE team.

Doing ECC/ECDSA may be taking too long without SEC engine.
LSDK only provide RSA support.
There are ECC/ECDSA reference code on the internet. We neither support or endorse it. Customer can use it at their own risk.
