I'm specifically using the discovery kit for the STM32F746G - Disco board. I've used STM32CubeMX to generate the configuration with no mods and then the code for atollics Truestudio, keep getting interrupts from TIM6

[jdowdster]

i can see both in the tool and the source code that the TIM6 timer is not configured. It is in fact the TIM6_DAC_IRQHandler() I keep ending up in.

Now it's easy enough to just force it to be disabled but I'm trying to figure out how to disable it in the tool. TIM6 is greyed out and the DAC system is all in red.

Ooops Sorry, I just tracked it down. It's the timer being used as the system tick. Turning it off might not be the healthiest approach.

Piranha,

Thanks for the help. I followed the steps laid out by SEGGER and the system is working much better now.

Cheers!!
