ChibiOS Free Embedded RTOS

Hello,

see the following bug:

- ChibiOS version or subversion revision number: Chibios 17.6 ID 1b08f1048f57587545f3854409dacccb91466fed
- Compiler: GCC 6.3
- Platform and board: STM32F40X
- Nature of the problem

When using GPT with TIM1 in chibios, there is a compiler error since commit ...

When entering standby mode the program starts again from the beginning, so that's not the fault.

I found a solution now, it seems that the optimizations lead to problems. This solution works with -O0, but fails with -O2:


...
//enter standby mode
chSysLock();
PWR->CR |= PWR_CR_CWUF ...

PS: WakeupPin rising edge doesn't work either.

Hi Barthess,

thank you for the ideas.
The board does not have a battery, the vbat pin is connected to 3,3v.
As long as the program is running, the RTC works. The RTC alarm is working as long as I do not enter standby mode.
Do I have to reconfigure some registers to make sure that the RTC keeps ...

Hey guys,

I experience problems when trying to enter the standby mode and waking up after a few seconds again with a custom STM32F103C8 board.

I took the code from the testhal/RTC example and used it in a simple application:


int main(void)
{
halInit();
chSysInit();
palSetPadMode(PORT_DBG ...

I had the same problem before.

You can solve it by formatting the SD card as a primary partition (and not a logical, which is the default type). User for example the "MiniTool Partition Wizard Home Edition" which is free.

Now that I'm playing around with it, there is one more thing missing:

If you want to use functions from chrtclib.c, you have to add the defines for STM32F30x (and probably STM32F37X) in chrtclib.c:

before:
#if (defined(STM32F4XX) || defined(STM32F2XX) || defined(STM32L1XX) || \
defined(STM32F1XX ...

I'm quite new to chibios but I'm starting to love it I'm working with the stm32f3discovery board and started today to use the RTC. The stm32f3 has a rtc, but to get it to work with chibios, the platform.mk must be extended with the following lines:

PLATFORMSRC:
"${CHIBIOS}/os/hal/platforms/STM32 ...
