ChibiOS Free Embedded RTOS

Hi! I edited the last post. It is exti_serve_irq(pr, 0); prevents the callback,
becaure pr = 4, and ((pr) & (1U << (0))) == 0.
I tempeory change exti_serve_irq(pr, 0); to exti_serve_irq(pr, 2); So that I can use the new Chibios_20.3.1
thanks for the help.

Hi!

the ISR is reached !
pr = 4
exti_serve_irq(pr, 0);

stm32_isr.c line 43:
#define exti_serve_irq(pr, channel) { \
\
if ((pr) & (1U << (channel))) { \
_pal_isr_code(channel); \
} \
}

so _pal_isr_code(channel) function is not called?

the Line is PAL_LINE(GPIOD, 2U)

Hi! I have a project use Chibios19.1.3. I upgrade to the lastest Chibios_20.3.1. After that, the pal callback is not working.
I use "palEnableLineEvent" and "palSetLineCallback" the set the line and the callback function. the hardware is stm32f765zg, I set the chip define to "STM32F767xx" to "board ...

I get the same error message. After I change "USE_LINK_GC", "USE_LTO" from NO to Yes. Problem is solved. I am using ChibiOS_19.1.3 and gcc 10.1.0
