In STM32H735IGT mcu I have initialized ADC1 and ADC3 in DMA method, also FreeRTOS is initialized. But ADC1 adc data is not obtained. But i can read ADC3 data. What may be the issue? One of the differences i have identified is continouous DMA request enable option is not available in ADC1. Also I have tried with basic adc polling method still ADC1 is not working. System clock I have enabled as timer 6 since for FreeRTOS req system clock should not be systick. Attached below  code.
