Re: Jump to bootloader.

I want to do exactly the same thing in my next project. Which exact STM32 model were you using? I guess the bootloader code is quite different between the series, as they have a wide variety of different features. Were you able to implement Giovannis suggestion, a module after vector.S and before cr...

Re: RISC-V Port of ChibiOS

I don't know if you are aware of it, but Gigadevice has the GD32VF103 available. This is interesting for ChibiOS I think, because it is a RISC-V mcu which contains the well-known peripherals from the STM32F103. So a port would "just" need to take care of the processor core, the peripherals...

Re: board files, tools/ftl reorganized ?

I had the exact same issue before, see http://www.chibios.com/forum/viewtopic.php?f=38&t=4589#p33624 for a detailed analysis of the problem and a suggestion how to fix it.

Re: USB HS on STM32F730Z

But wouldn't it be better to just fill in a few other AF positions in the matrix to give you a few more options to move things around instead of requiring the much larger package? I don't know why they did it like that. I guess there are technical reasons. Maybe the HS PHY IP they licensed allows o...

Re: USB HS on STM32F730Z

(*) The fact that only the physically larger versions have this hints to me that they might be adding an ULPI chip inside the package. On the other hand, this is the "value line", so not a chip where you expect a multi-chip-package. The first thing I look at when trying to figure out such...

Re: UART DMA receive in circular mode

I concur that the circular buffer implementation won't be easy to implement in a correct way. You would have to suspend DMA operations, do your read/write then resume DMA operations, I am not even sure it is possible to suspend/resume DMA channels. How about using two buffers instead of the circular...

Re: [INFO] Functional Safety Elements

I'm not working in an industry with specific functional safety requirements, so I'm not that experienced with such requirements and norms. But I still like to improve the reliability of the stuff I build if it doesn't take too long to implement. Here are some more ideas in this area from me: - Flash...

Re: [INFO] New Library Generator tool

Could you elaborate more what the usecase for a binary distribution of the os is?

Why not compile it with your program? The makefile system of ChibiOS works really well, rebuilding the whole os just takes a few seconds on a recent machine.

Re: Interesting Error on STM32F030K6 with remapped serial

Unfortunately the other problem related to __builtin_return_address is still open and unfixed:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88656

So for the time being you still can't use a recent gcc for ChibiOS on Cortex-M0 / Cortex-M0+.

Re: Reset reason

Is there already any HAL code for this available that I could test?

I'm just working on a project where I need to check if the watchdog triggered a reset and alert the user that something went wrong.

Thanks.
