ChibiOS Free Embedded RTOS

I downloaded latest ChibiStudio for Linux. My local openocd version 0.12.0.
Config options are next:
-f interface/stlink.cfg -f target/stm32f1x.cfg -c "$_TARGETNAME configure -rtos chibios"
But there is no success.

I can't check on very old GCC. On GCC 7 auto is good.

Hi All,
After migration from older GCC to 10.2 linker produces warning regarding incorrect usage of -flto
I found that in ChibiOS it without value but should be with value.
I added next thing and warning doesn't appear anymore. Is it correct way?

Hi All,
I have found that it's impossible to use TIM16 without fix becuase of missing STM32_TIM16_CHANNELS def.

There is a simple patch:

diff --git a/os/hal/ports/STM32/STM32L4xx/stm32_registry.h b/os/hal/ports/STM32/STM32L4xx/stm32_registry.h
index fdec353fa..8a795ba00 100644 ...

Hi All,
I started a small experimental project on this board: https://stm32-base.org/boards/STM32F401 ... -Mini-F401

By the way I extracted a demo fro this board in ChibiOS and committed to separate branch on github. https://github.com/tuxford/chibios_hw84 ... 48_21.11.x

I think it has sense to add it to your main stream.

Hi Giovanni,
You are right!
I missed a case when one message was sent twice with different flags that were handled in wrong way.

I case EVENT_MASK it's good. I used it instead of lshift operation.

But I still have a question about chEvtWaitOne.
Does it wait one message and if other of the same id ...

EVENTSOURCE_DECL(spindle_state_es);
EVENTSOURCE_DECL(spindle_es);

#define EVENT_STATE EVENT_MASK(0)
#define EVENT_TRIGGER_VALUE EVENT_MASK(1)
#define EVENT_ENC1HS_SLOW EVENT_MASK(2)

#define SUBEVENT_TICK EVENT_MASK(0)
#define SUBEVENT_ATTACH EVENT_MASK(1)
#define SUBEVENT_ATTACH_FAILED EVENT ...

I understand difference between events and flags. There no problems. Code is too long to show it.

I was investigating how broadcasting works but I haven't have a clear idea how it's better to find out where event gets lost internally.

Hi,
I faced with a problem when I use events. I have declared 29 events using macro EVENTSOURCE_DECL. But after adding flag for event I found that chEvtBroadcastFlags doesn't send it or chEvtWaitOne(ALL_EVENTS) doesn't receive one exact event. Other important thing is that if I drop one evtTableHook ...

I2C driver stop working after first failed command. E.g.

uint8_t addr = 0xFF << 1;
i2cMasterReceiveTimeout(drv, addr, NULL, 0, TIME_S2I(2));

On oscilloscope i have next case. SCL is on low state and that's finish. No operations are allowed until restart of board.
