Re: undefined reference to ST2MS and MS2ST

That warning has already been fixed in repository, it will be in next release. Note that it has no real impact.

Re: Exception handling using longjmp()

The context saved by setjmp does not save some internal registers used by chSysLock/chSysUnlock (BASEPRI), you should not assume that the interrupts masking state is preserved/restored.

Re: Where to start STM32H7 support

I will change all defaults in mcuconf files. It could be a good idea to report this to ST via forum and see if they have an answer.

Re: [MAINTAINERS] Low Level Driver organization changes

xFaisal, The change is not just that, now the xxxConfig and xxxDriver structures are defined in the upper layer, the LLD extra fields are exported by the LLD into a macro. This way, when there is a change affecting just the HLD, there is no need to rework all LLDs. xTheo, Look at the files under os/...

Re: undefined reference to ST2MS and MS2ST

Hi,

In recent version of RT there are two different types one for absolute time (systime_t) and one for intervales (sysinterval_t), because of this those macros have been renamed to TIME_MS2I(msecs) etc, look into chtime.h, all time/interval-related macros and functions are there.

Re: Exception handling using longjmp()

Hi,

You should have a separate "env" structure for each thread, it should work.

Re: Where to start STM32H7 support

It must be some kind of glitch, it looks like the DMA is triggered twice for each frame, this is why the output is interleaved with zeros.

Re: RTC inconsistent weekday

It could be a bug, RTCv1 hasn't been used much, just F1 used it.

Re: Where to start STM32H7 support

Good to know it works now. But why only on BGA devices?

Could you try DIV4? then try to halve SPI speed using DIV2?
