ChibiOS Free Embedded RTOS

change the c/c++ preprocessor symbols to "__heap_base__=Image$$$$RW_IRAM1$$$$ZI$$$$Limit __heap_end__=Image$$$$RW_IRAM2$$$$Base" and magically it compiles without issue and works (on the one board I tried). This is for MDK5.14.0.0 - so I don't make any promises for earlier versions.
I confirm that ...

Hello!
When compiling with trunk (rev.8011) I got this error from make:

os/hal/ports/STM32/STM32F1xx/platform_f105_f107.mk:78: *** missing separator (did you mean TAB instead of 8 spaces?). Stop.

This file lacks a trailing back slash in line #78. Patch attached.

Hello!

In recent ChibiOS 3 I found that the rccEnableCAN2() (and others for CAN2) is absent at all in os/hal/ports/STM32/STM32F1XX/stm32_rcc.h
STM32F10X_CL devices have 2 CANs. In ChibiOS 2.6 it present.

Patch attached.

Thanks!

Hi!
I found an issue in OTGv1 usb_lld.c: in case when CORTEX_SIMPLIFIED_PRIORITY = TRUE a special assumption that OTG FIFO operations must not be interrupted is not satisfied.
New code:

#if (CORTEX_SIMPLIFIED_PRIORITY == FALSE)
#if (STM32_USB_OTGFIFO_FILL_BASEPRI > 0)
__set_BASEPRI(CORTEX_PRIO ...

Hello!

Some tasks with extensive IRQ usage needs a way to clear pending interrupts.
I request a simple function in NVIC like this:


Patch attached. Thanks.

with classic periodic time

system works, no hangs. So I assume this is somewhat related to freerunning timer on TIM2.

No, IRQ priorities at level 0/1 are not used.
Without debug in chconf.h system works, but I encountered some sort of hangs due to stack overflow or something during USB transfers, so decided to enable debug in ChibiOS and right after that I have found this issue (even without my code).
config files ...

Hi!
Problem was found in ChibiOS/RT 3 (rev.7788): with enabled debug in chconf.h

#define CH_DBG_SYSTEM_STATE_CHECK TRUE
#define CH_DBG_ENABLE_CHECKS TRUE
#define CH_DBG_ENABLE_ASSERTS TRUE


Interrupt from timer TIM2 (STM32F105) generated after chThdSleepS() calling and before chSysUnlock ...

Hello Giovanni!
Why the change in chcore_v7m.h? That "U" is required for MISRA compliance.

That's why:
