I tried

to configure the

CAN

controller

in the

STM32F042F6P6

using

STM32CubeMX.

The function

was not

correct

because

it

was not

properly

remapping

pins

PA11

, PA12.

Macro

__HAL_REMAP_PIN_ENABLE

does

not

activate

SYSCFGCOMPEN

:

SYSCFG

&

COMP

clock

enable

.

Version: STM32CubeMX

4.6.0

,

STM32CubeF0

1.2.1

I

made a change

in the file

stm32f0xx_hal_msp.c,

function is

correct now:

HAL_MspInit

void

(void

)

Don't assume to know initial conditions, or break them, use
