CubeMX problem when generate codes.

[TSuzu.424]

Hi,

DMA does not work, because the initialization order of the code generated by CubeMX is not correct.

DMA setting is not valid, because DMA is initialized after the fuction that uses DMA.

Please fix bugs.

Best regards,

incorrect order expample:

MX_GPIO_Init();

MX_SPI1_Init();

MX_SPI2_Init();

MX_SPI3_Init();

MX_UART4_Init();

MX_UART5_Init();

MX_USART1_UART_Init();

MX_USART2_UART_Init();

MX_USART3_UART_Init();

MX_DMA_Init();

correct order expample:

MX_GPIO_Init();

MX_DMA_Init();

MX_SPI1_Init();

MX_SPI2_Init();

MX_SPI3_Init();

MX_UART4_Init();

MX_UART5_Init();

MX_USART1_UART_Init();

MX_USART2_UART_Init();

MX_USART3_UART_Init();

My environments:

・STM32CubeMX Ver. 5.4.0

・STM32Cube MCU pacage for STM32L4 Series Ver1.14.0

・Windows10

・NUCLEO-L496ZG

Hello,

The initialization order can be changed directly within STM32CubeMX, just go in the "Project Settings" tab, "Advanced Setting: section.

In the table "Generated Function Calls", you can select each line and thanks to two buttons at the bottom of the window, you can increase or decrease the rank of each function call.
