Re: STM32H7: Support for Multiprocessing between Cortex M7 and Cortex M4

Hi Frank-Christian, The port is to Cortex-M7, but since NuttX also supports Cortex-M4 it could be possible to run NuttX at both at same time. I don't know if the PX4 guys already did it, maybe... BR, Alan On 8/4/20, Frank-Christian Kruegel wrote: > Hello World; > > I'm about to choose a Cortex

STM32H7: Support for Multiprocessing between Cortex M7 and Cortex M4

2020-08-04 Thread Frank-Christian Kruegel
Hello World; I'm about to choose a Cortex M7 microcontroller for a new project. All major vendors (Atmel/Microchip SAME70/V71, STM32F7/H7, NXP IMXRT) seem to be supported. In the list of supportex boards I see a STM32H747i Discovery. The STM32H747 has both a Cortex M7 core and a Cortex M4 co

Is there a working document or set of notes detailing ongoing/needed work for STM32H7 support? Not really - a diff to the F7 file usually will show the holes but there is also the datasheet diff view. What do you mean by datasheet diff? We used SDMMC2 in all H7 designs and that choice

Hi all, Is there a working document or set of notes detailing ongoing/needed work for STM32H7 support? I've looked through the code in arc/arm/*/stm32h7, release notes, board README, and commits/issues/PRs on github to piece together some of what has been worked on.  It appears that a l
