imx6ul, u-boot CAAM blob_encap() fails

Hi all,

porting some imx6sx crypto-related code to imx6ul, but the blob encapsulation function (blob_encap(), drivers/crypto/fsl/fsl_blob.c) seems not working.

As function parameters, i am passing the buffer with a key to encapsulate, but the blob output buffer remains untouched, all 0. Like the CAAM module is not performing any action. Hope someone can provide some help on this.

 

Thanks

Regards,

angelo
