Yes, when you get DMA TC, at least one frame is still outgoing, on UARTs with FIFOs potentially more than one but this is not the case on F4.

LIN mode would not be a problem, it just enables break detection and generation. Why do you think there is an assumption for breaks? it just detects a long sequence of zeros. I think that it is the use of FE that is not reliable, probably this is not a SW issue. Just give break detection a try and s...

Hi,

Hard to give suggestions, it is a very specific use case.

Doesn't the STM32 UART have a break detection feature? why use FE?

Hi,

I will do another update in 21.x in 2 or 3 weeks, lots of bugs are being fixed in trunk and I want it to be super reliable before going for 25.x or 26.x.

Commercial customers on 21.x will be aligned to this new version, please check your support status.

The driver assigns the DMA channel priority to the DMA channel IRQ priority possibly resulting in an invalid priority level assigned.

Hi,

There is no C++ equivalent, I will look into adding .cpp and .hpp support to /source.

You could give it a try yourself, it is one of the .mk inclusions in makefiles and it is not that complex.

Giovanni

Something is missing in the Makefile, those types are fundamental.

Make sure to take a makefile from a demo then add your source code under /source (no need to add files to the makefile, anything under /source is compiled automatically).

Giovanni

The error does not occur in demos, make sure that you have everything is needed in your makefile, it could be a missing path.

You could zip a minimal project with the failure so I can verify it.

Hi,

What are you compiling?

Hi,

Last time I ran the test application STM32-WSPI-MFS it worked so it seems something specific in your board port, check clocks and GPIO settings.
