Re: [DEV] STM32L5xx support

Hi Giovanni,

What gdb server have you been using for this development? I've searched for OpenOCD support and only found this abandoned patch http://openocd.zylin.com/#/c/5386/

Re: c++20 : semantic change of volatile keyword

I think the intent is to clear the muddy usages of volatile, frequently confused with atomicity in multithreaded development under C++. The qualifier will remain present for load and store operations, in here Jf Bastien's mentions having a more expressive alternative perhaps something like volatile_...

Re: Ethernet PTP time stamp status register bits Topic is solved

Ok,

Out of curiosity, where are the ST CMSIS headers downloaded from?

Thanks,

Ethernet PTP time stamp status register bits Topic is solved

Hi, The following should be applicable to ST family (os/common/ext/ST/) with TSTTR & TSSO defined. Assuming 17.6.3, changes should be: #define ETH_PTPTSSR_TSTTR 0x00000002U /* Time stamp target time reached */ #define ETH_PTPTSSR_TSSO 0x00000001U /* Time stamp seconds overflow */ In 18.2.1 the p...

Re: L432KC i2cMasterTransmit freezes

Hi Angelo, Quick couple of questions, in your specific setup with your STM32L432 when you had to drop the system frequency sourced by the RC oscillator (MSI), did you also have the LSE enabled too? What frequency is your CAN bus running at? I found the following from the documentation: Multispeed in...

Re: L432KC i2cMasterTransmit freezes

Quick update, run it on the stm32nucleol432 I ordered and no problems at all with I2C.

Re: Thread scheduling - unexpected behavior

Hi Alexandre,

Thanks for taking the time of actually run it and shedding some light, that makes perfect sense (so great to know the cause !). Didn't realiaze about the atomicity of the toggle call.

Also never heard of bit-banding before, appreciated.

Re: Thread scheduling - unexpected behavior

Hi Giovanni, Main() is a thread at priority NORMALPRIO, if it does not release the CPU then all threads at lower priority will never be scheduled, other threads at NORMALPRIO would be scheduled only if main() calls chThdYield() or its time slice elapsed (depending on if RR scheduling is cooperative ...

Re: Thread scheduling - unexpected behavior

Hi Wurstnase, That was quick :) Could you elaborate on that please? Is that specific to the main thread? Would the result be any different if I moved the main thread to a separate one, lower priority than blinker and main to sleep infinitely? From a theoretic perspective, any reason not to have a lo...
