Thread scheduling configuration
Ciao Giovanni, I would like to understand more about your comment in that thread where you advised on thread scheduling: https://forum.chibios.org/viewtopic.php?t=5408#p37219 #define CH_CFG_ST_FREQUENCY 10000 -> 1000 (10000 is too high without tick-less mode) #define CH_CFG_ST_TIMEDELTA 2 -> 0 (disa...

Re: SPI STM32H7 (SPIV3) and lld-v1
One resource that has been useful to me in the past when struggling with DMA and cache coherency on H7: https://www.chibios.org/dokuwiki/doku.php?id=chibios:articles:cache_coherence One thing you can try is to use spiPolledExchange instead of spiExchange , my understanding is the former doesn't rely...

Re: halconf and preprocessor switches
Sounds good - trading some compilation time in that case is totally fine. Thank you Giovanni.

halconf and preprocessor switches
Seeing how halconf.h is laid out with preprocessor switches like: #if !defined(HAL_USE_SIO) || defined(__DOXYGEN__) #define HAL_USE_SIO FALSE #endif I expected to be able to set HAL_USE_SIO in the Makefile (e.g. USE_OPT+= -DHAL_USE_SIO=TRUE) as an alternative to editing the halconf.h file. I ran int...

Re: [DEV] STM32G4xx support
I am wondering about ADC5 support : I see earlier in this thread that support was not added at the same time as ADC 1...4. What's different about ADC5 that we can't mimic what's been done for the other ADC in its group, namely ADC3 and ADC4?

Re: Where to start STM32H7 support
Just got my hands on a H723ZG nucleo 144. Current H7 demo cover H743, H750, H755 but there aren't any for H72x. Is there anything specific to that family I should know before embarking on creating a new demo project, along the lines of what's described there ? https://www.playembedded.org/blog/port-...

Binary size difference between gcc9 and gcc10
I am giving ChibiStudio 2021-07 a spin. First of all, thanks for the update ! I was checking the demo project RT-STM32F446RE-NUCLEO64 and noticed a significant binary size difference between the two gcc versions. For gcc9: text data bss dec hex filename [b]46872 220 130848 177940 2b714 build/ch.elf ...

Incidental question: I don't see a 20.3.4 version released from the github mirror:
https://github.com/ChibiOS/ChibiOS/releases
When is github updated?

Re: [DEV] The new SIO driver
Just came upon that promising feature.
Is there a time-line for inclusion of SIO in a release? I do not think I have seen that yet.
