Hi,I am using DMA1 stream 3 for USART3 for tx on an stm32f429.Driver code is based on cubemx generated st hal drivers firmware package version 1.24 The uart and dma initalisation parameters are as follows:huart3.Instance = USART3;huart3.Init.BaudRate...

I just installed en.stm32cubeprg-win64_v2-7-0.zip.Installation went without problems but when I try to start the application I get the splash screen and then it just exits apparently. If I runt it from a prompt I get no messages.C:\Program Files\STMi...

After connecting a STN32H735G-DK board to my windows 7 pro pc, the com port driver gives an error "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file ...

Hi, I would prefer to use my segger jlink debugger with the discovery board io using stlink. I see there is an unpopulated header with 3V3 , SWCLK, GND, SWDIO on the left side of the board, and there is an NRST pin on the back connectors so I think ...

Regarding the race condition remark:You take the semaphore (well , you would if the check was correct but lets ignore that for now), start a dma action and then overwrite your buffer , so DMA is potentially still using the data while you are writing ...

The Freertos example you refer to is a situation where you consume the semaphore gives that are generated by a timer task that runs continuously.There is no launching of an asynchronous event there of which the launch might fail so you do not have t...

>FreeRTOS explicitly says you don't need it when you have xSemaphoreGiveFromISR in in an ISR.I am sorry I am not following, what exactly is "it' in that sentence ? >So for testing i did what you've done. I can replicate your issue where i get FIFO er...

I am now wondering if the problem might be related to sleep states of the processor.I am sure I am not going into stop mode, but I do have Freertos 'tickless idle' enabled which also relies on the __WFI instructionIf i quickly skim through 'https://c...

Karl,That is the error path , where you can only come if a DMA transfer was not started so that the transfer complete callback will never happen.If you do not release the semaphore in the error path, it will never be released and all future transmiss...
