STM32CubeMX - SAI Code generation problem.

[Howcroft.Paul]

Posted on December 04, 2014 at 10:33I am developing an application using the Serial Audio Interface of the STM32F429ZITx.There appears to be a problem in the code generated by STM32CubeMX.The DMA handle hdma_sai1_a is declared as a global variable in main.c.The same variable name is declared as static within the scope of the function HAL_SAI_MspInit() in stm32f4xx_hal_msp.c.The consequence of this is that the DMA2_Stream1_IRQHandler() function uses the incorrect un-initialised DMA handle and no transfer complete callbacks are invoked.Workaround:Remove definition of hdma_sai1_a from HAL_SAI_MspInit().Add ''extern DMA_HandleTypeDef hdma_sai1_a;'' to  stm32f4xx_hal_msp.c.

Configuration:

MCU : STM32F429ZITxSTM32CubeMX : v4.5.0STM32Cube FW : v1.3.0Atollic TrueSTUDIO : v5.2.0 #stm32cubemx-sai

Hello,

this issue is fixed for next release (STM32CubeMX 4.6) coming out soon. Sorry for the inconvenience.
