STM32CubeMX possible bug

I use STM32CubeMX v 4.0 to configure CMSIS SPI Driver. I believe I do right DMA configuration:

But after code generation file MX_Device.h hasn't defines to enable DMA for SPI.

/* DMA Configuration */
/* DMA SPI2_TX */
/* DMA SPI2_RX */

So, I have to modify it to enable DMA:

/* DMA Configuration */
/* DMA SPI2_TX */
#define MX_SPI2_TX_DMA_Instance DMA1_Stream4
/* DMA SPI2_RX */
#define MX_SPI2_RX_DMA_Instance DMA1_Stream3

#stm32cubemx #dma #bug

Hello,

Please share your .ioc to check this case.

In which folder is defined MX_Device.h ?

Regards

Hi,

I used the example project CMSIS-RTOS Blinky (STM32F4-Discovery) in Keil MDK-ARM 5. And then configured SPI1 via STM32CubeMX. After the code generating I got same problem. The MX_device.his in \MDK\Boards\ST\STM32F4-Discovery\Blinky\RTE\Device\STM32F407VGTx\ folder.

.ioc file attached

Hello,

Please share your .ioc to check this case.

In which folder is defined MX_Device.h ?

Regards

Hello Eugene,

I want to thank you for your bug report, this is helpfull for us to improve our SW offers.

I try to locate the file and reproduce your issue.

I download latest uVision tool - V5.21.1.0

I install the latest Keil pack version for ST F4 family - 2.10.0

it has been installed, on my windows machine, here C:\Keil_v5\ARM\PACK\Keil\STM32F4xx_DFP\2.10.0

Can you check which version do you have installed on your machine ?

The pack version can be obtain, as well, into Project->Manage->Pack Installer : right side -> Packs tab, select ''Device Specific'', and expand ''Keil::STM32F4xx_DFP''.

The file you mentionned does not exist in that version, howether a file named RTE_Device.h does.

It has all SPI DMA definition (in a slightly different writing) has you describe in your post.

I guess here that this project example has been updated by ARM.

The header of this file indicate that this is provided ''as is'' by ARM.

As far as I know, this file is not generated by CubeMX.

Kind Regards

Sirma

Hello,

I have the exact same versions. MX_Device.h was generated by STM32CubeMX. So, first you have to configure your project to use STM32CubeMX: http://www.keil.com/pack/doc/STM32Cube/General/html/cubemx_proj.html After you click ''Project - Generate Code'' in STM32CubeMX you'll get you MX_Device.h file. This is mine:

HEllo Eugene,

Thanks you for all your inputs.

By loading your ioc in CubeMX, this file is not generated, but by launching CubeMX from Keil (as it is describe in your link) then much files are generated, including this file.

As this is out of my knowledge, I forward this bug to the relevant team.

Kind Regards

Sirma
