Is it possible to execute multiple ECDSA Sign operations within the same i.MX8 job descriptor?

I need to execute ECDSA operations in parts. When the job descriptor includes an  ECDSA part 1, or ECDSA part 2, the operator works as expected, so it does when the ECDSA part 1 is followed by ECDSA part 2. But if the job descriptor includes further ECDSA operations after an ECDSA part 2, the additional ECDSA operations seem to execute without error, but the outputs remain unmodified.

 

Are they limitation on the number of ECDSA operations that can be executed within the same job descriptor? Can an ECDSA part 2 be followed by another ECDSA part 2 operation in the same descriptor?
