STMcubeMX don't generate code for DMA

Hi.

I am trying to generate code via STMcubeMX for UART via DMA. I have configured the UART and DMA correctly to my liking, but when I press generate source code the only code for the DMA is:

/**

* Enable DMA controller clock */static void MX_DMA_Init(void) { /* DMA controller clock enable */ __HAL_RCC_DMA1_CLK_ENABLE();

}

When I look into the logfile for 

STMcubeMX I can see when it is trying to generate the code for the DMA it gives these errors:

[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (Channel) has Id (UART5_RX) currently not set

[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (PeriphDataAlignment) has Id (UART5_RX) currently not setINFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (MemDataAlignment) has Id (UART5_RX) currently not set[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (Mode) has Id (UART5_RX) currently not set[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (FIFOMode) has Id (UART5_RX) currently not set[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (FIFOThreshold) has Id (UART5_RX) currently not set[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (FIFOThreshold) has invalid value (null)[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (MemBurst) has Id (UART5_RX) currently not set[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (MemBurst) has invalid value (null)[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (PeriphBurst) has Id (UART5_RX) currently not set[INFO] ImportTextPane:147 - (OptionalMessage_ERROR) IP (DMA) : Parameter (PeriphBurst) has invalid value (null)

When i look at the parameters it throws an error for I can see that it is set. 

Do anyone have a solution so I can generate code for the DMA?

Attached is the log-file and the IOC-file

#dma #stmcubemx #optionalmessage_error

I have no trouble with CubeMX, for the DMA on Usarts... on the '091

are you using 1.7.0 ?

which processor is it ?

Hello

‌,

Which version of HAL are you using ?

I created new project with your same configuration and I have

MX_DMA_Init() function as below

:

/** * Enable DMA controller clock */static void MX_DMA_Init(void){ /* DMA controller clock enable */ __HAL_RCC_DMA1_CLK_ENABLE();/* DMA interrupt init */ /* DMA1_Stream0_IRQn interrupt configuration */ HAL_NVIC_SetPriority(DMA1_Stream0_IRQn, 0, 0); HAL_NVIC_EnableIRQ(DMA1_Stream0_IRQn); /* DMA1_Stream1_IRQn interrupt configuration */ HAL_NVIC_SetPriority(DMA1_Stream1_IRQn, 0, 0); HAL_NVIC_EnableIRQ(DMA1_Stream1_IRQn);}�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?

Try creating new project in proper/new folder, thenkeep me informed about your updates.

Regards

My STMcubeMX is on version 4.1.9

You should use the last version of STM32CubeMX 4.19.0

When I generated a new file I got the correct code and no errors in the log-file. Weird that it didn't work on my original project. I used version 1.6.0 of HAL.

Oh, sorry, I meant 4.19.0,
