G474RE + Workbench6.4.2 HSO：ADC trigged by TIM3 or TIM1 ??
I am developing a control board based on the STM32G474RE microcontroller. This board is self‑designed using Board Designer within Workbench 6.4.2. After configuration and project generation in Workbench, the generated project works fine. The HSO option can be enabled, and no errors or warnings are reported for all parameters. Compilation in MDK‑ARM completes without any issues. I have reviewed the initialization code for ADC1 and ADC2, which are used for phase‑current and phase‑voltage sensing. In principle, the HSO measurement mechanism relies on synchronization with the PWM signals. The PWM waveforms are generated by TIM1. However, I observe that TIM3 is configured as the input trigger source for the ADCs in the initialization code, instead of TIM1 as I expected. Is this a bug in the code‑generation output? Please provide assistance.
