STM32f373 multimode simultaneous on SDADC1 & SDADC2

Hello, I am trying to configue SDADC1 and SDADC2 in injected mode to read simultaneous values on the 2 converters. Using CUBEMX I configure injected mode for SDADC1 and sync mode for SDADC2 .

Problem SDACD2 always read 0.

Any working example available ?

Thank you Luca
