STM32MP1 support available in SW4STM32

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4; you can download a short video showcasing this on the ac6-tools website (registration required).

Configuring CubeMX for simple PWM

Hello,

I am completely new to STM chips and ARMs.

I want to make a simple PWM.
I have Nucleo F072RB.
I use CubeMX and TrueStudio.
I followed this tutorial to understand the registers better:
/watch?v=xs9lGF--QcU
At the end of the third video, the guy has a functioning PWM simply by configuring the registers properly.

I tried to configure cube MX as best I could. I used PA11 as the output. Using Timer1 channel 4.
I get no PWM.

Here are the configs. I tried various combination.
T1M Mode TIM Config
If I make a project where without configurating the T1M and pin PA11. The GPIO config function MX_GPIO_Init(); is identical as when I configure PA11. it’s like Cube MX doesn’T even initializes PA11.

This is the function:
static void MX_GPIO_Init(void)
{
GPIO_InitTypeDef GPIO_InitStruct = {0};

/* GPIO Ports Clock Enable */
__HAL_RCC_GPIOC_CLK_ENABLE();
__HAL_RCC_GPIOF_CLK_ENABLE();
__HAL_RCC_GPIOA_CLK_ENABLE();

/*Configure GPIO pin Output Level */
HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, GPIO_PIN_RESET);

/*Configure GPIO pin : B1_Pin */
GPIO_InitStruct.Pin = B1_Pin;
GPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING;
GPIO_InitStruct.Pull = GPIO_NOPULL;
HAL_GPIO_Init(B1_GPIO_Port, &GPIO_InitStruct);

/*Configure GPIO pin : LD2_Pin */
GPIO_InitStruct.Pin = LD2_Pin;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
HAL_GPIO_Init(LD2_GPIO_Port, &GPIO_InitStruct);

}

Where is my PA11 setup?
