Generated a project for STM32F746 (Firmware Package for Family STM32F7 v1.8.0) that uses ADC1 + DMA + TIM6 (TRGO) for Keil MDA-ARM 5. Tried to run it - no trigger is received by ADC, so no convertion data is transferred over DMA.
The bug is documented in "STM32F74xxx STM32F75xxx Errata sheet", page 7 (2.2.1). Workaround is to turn on CLOCK for DAC.
Please fix the bug in code generating .
