Re: STM32L4+ support
What is the status on the OS and HAL support for these devices? I'm expecting some custom boards with this processor soon ... One significant change seems to be the DMA controller.
I would appreciate an update, or some sort of estimate on when it will be supported so we can plan around it.
Thanks!

Re: STM32L4+ support
Some code has already been committed, no estimates yet. DMA support will be the same already done for H7, most drivers too.

Re: STM32L4+ support
Update, it is proceeding, I am fining a lot of differences in ST headers. Apparently they decided to change register macro names because reasons...
Doing the patchwork...

Re: STM32L4+ support
Did anybody manage to make OpenOCD work with STM32L4plus? the current git master does not seem to support it.

Re: STM32L4+ support
I've built the L4R5-NUCLEO demo on trunk and flashed it with ST-LINK to a NUCLEO just to see if the LEDs blinked.
Blue and red do... green "looks" solid (or blinking at high rate perhaps).
Pressing USER button didn't produce test output via SD3->USB.
It seems we'd require a Windows build of openocd with this "cherry pick" update included to at least get started on ChibiStudio...

Will look at patching and building openocd as time permits.

Re: STM32L4+ support
The demo is not tested (I am trying to setup OpenOCD just in order to do that).

Re: STM32L4+ support
Giovanni.
Here is a quick hack W64 build of openocd that will at least get you running with L4+ testing.
I built it using Liviu Ionescu's GNU MCU build system for openocd.
Use board/st_nucleo_l4.cfg for session establishment.
There is no support for sector erase yet in the openocd patch for L4+ NOR flash.
Not sure if anyone is doing further work on the L4R/Sx support.
I have an L4R9 project in the works so would be good to have some further work on this soon...
Cheers,
