Bug in STM32CubeMX v 4.22.0 with dual ADC mode

When I had generated code with dual ADC on regular simultaneous mode from STM32CubeMX, the code after compiled couldn't get to work and rised error handler, so I traced the problem, found that there is a multiple mode configure function in ADC init function, but the configure function only works with ADC1, here is the reason. and I will illustarte it below:

1. Here is the configure of ADC1 and ADC2
2. This is the code in ADC2_Init function:
3. The source code of this function, in the read box, the statement will be false:
4. Here is the macros:

So, this code in ADC2_Init is meaningless, and bolck the program, I have to delete it everytime after I regenerated the project.

Hopes It's usefull for your guys.

Best Regards,

Zheng.

And, the code generated in ADC2_Init function, lacking 'hadc2.Init.ExternalTrigConv = ADC_SOFTWARE_START;' as Ali said in
