ChibiOS Free Embedded RTOS

I am sorry, I just did not pay attention. SORRY!!!!

But your correction didn't help. I receive exactly HardFault exception, which received before:
- HardFault_Handler() at vectors.S:463 0x208994
- <signal handler called>() at 0xffffffe1
- __set_PSP() at cmsis_gcc.h:279 0x209dc0
- _port_irq ...

I really want to agree with you, but I took this definition from file:
..\os\hal\ports\STM32\STM32F7xx\stm32_registry.h

#define STM32_HAS_DMA2 TRUE
#define STM32_DMA2_CH0_HANDLER Vector120
#define STM32_DMA2_CH1_HANDLER Vector124
#define STM32_DMA2_CH2_HANDLER Vector128
#define STM32_DMA2_CH3 ...

Hi All,
I understood my problem. Thank you very mutch.
But now I have next one:
I see that MAP file doesn't has DMA2 channel 2 interrupt handler (Vector128, number 58):
.text.VECTOR128
0x00000000 0x10 os\hal\ports\STM32\STM32F7xx\stm32_isr.o

I declared the interrupt handler of DMA2 channel 2 the ...

I think I didn't explain myself.

I have the following task - write UART emulator on GPIO.
I finished write code and understood that interrupt handlers to ONE GPIO and TWO DMA I cannot insert to code: it is very difficult task.
I do not need internal OS code, I need :
1 config GPIO as interrupt in ...

Hi mr. Giovanni,

I am glad to write you.
I didn't find anythings that can help me to understood my problem.
May you guide me exactly to place, where exist needed code?

Thanks,
Alex

Hi All,
I am an old embedded engineer, but first time work on ChibiOS system.
My board is STM32F722ze and I must to write UART EMULATION on GPIO. (Maybe anybody has this code on ChibiOS ?).
I have find STM32F4 project, which explains every step, but I stopped interrupt declaration.

I need the TODO ...
