Conflicts with network and PWM on stm32f7 nucleo-144
Hi
I've configured a NUCLEO-F746ZG board with different devices:
* PWM (TIM3 3xOutput)
* QE
* ADC
* GPIO
CONFIG_PWM=y
CONFIG_STM32F7_PWM_MULTICHAN=y
CONFIG_STM32F7_TIM3_PWM=y
CONFIG_STM32F7_TIM1=y
CONFIG_STM32F7_TIM1_QE=y
CONFIG_STM32F7_TIM2=y
CONFIG_STM32F7_TIM2_ADC=y
CONFIG_STM32F7_TIM3=y
CONFIG_STM32F7_TIM3_CH1OUT=y
CONFIG_STM32F7_TIM3_CH2OUT=y
CONFIG_STM32F7_TIM3_CHANNEL1=y
CONFIG_STM32F7_TIM3_CHANNEL2=y
CONFIG_STM32F7_TIM3_PWM=y
but I have problems when I have PWM and UDP working together in a
pysimCoder block diagram.
Starting the application, the socket to the UDP is opened , but I don't
receive signals to the UDP server.
In addition, I can't open the RCP channel to the SIlicon Heaven
application correctly.
The problem disappears when I remove the PWM block in my diagram...
I've increased all the stacks, but without success.
Any Idea?

Today I test the possibility to exchange PA07 and PB05 as described
here, be removing SB121 and closing SB122 solder bridges on the back of
the nucleo board.

This an HW patch, but quite simple to be done.

I wonder if a compile-time check for this conflict could be added somewhere
to prevent this kind of impossible pinout assignment from being done again
in the future?

This is my configuration:
#define GPIO_TIM3_CH1OUT GPIO_TIM3_CH1OUT_2
#define GPIO_TIM3_CH2OUT GPIO_TIM3_CH2OUT_1
#define GPIO_TIM3_CH3OUT GPIO_TIM3_CH3OUT_1
#define GPIO_TIM3_CH4OUT GPIO_TIM3_CH4OUT_1
PA07 for PWM channel 2 is required by the Arduino Motor Shield, used to
control an external motor.
I can try to set another channel, and see if the problem disappears.
Thanks

Exactly! The problem is there. Setting the PWM channel to
#define GPIO_TIM3_CH2OUT GPIO_TIM3_CH2OUT_2
the problem disappears.
I need this PA07 to connect the Arduino Motor Shield (Motor B)...
I check the JP6, perhaps it solves the conflict.
Thanks and best regards

Do you use the default TIM3 outputs configuration from
nucleo-144/include/board.h ? It uses PA7 as the TIM3 channel 2 output which
is also used for RMII_CRS_DV.
From the nucleo 144 user manual:
