Hello to you All,

I am new to mynewt and the ARM world as you would figure out by my question.. I have a strong background in the 8-bit world where problems tend to be easier..

I am working on a STM32f756 were I need to enable quite a lot of DMA streams and also other peripheral functions (i.e. usb) I can't find yet in mynewt code.

I really like the mynewt concept and would love to use it for my application, a multimedia device with a touch tft, eth and wlan module.

So my question is, would it be able for me to use the mynewt kernel for the running system (tasks, console, fs, update) but configure and access the devices and the interrupts without using the API?

I did this when i tried to configure DMA for use with ADC1, but when I write the NVIC register using HAL_NVIC_EnableIRQ(...) this crashes my code, printing an "Unhandled interrupt (72)" to the console. When I comment out the enable function, the system doesn't crash, but obviously DMA is not working either.

I have the corresponding IRQ function in my code:
        void DMA2_Stream0_IRQHandler(void)

but it never gets called, system crashes immediately after activating DMA.


Any pointer in the right direction is highly appreciated!

Thank you very much

jan
