Using DMA Burst with OCToggle mode on F722ZE

Hi all,

I'm using the HAL drivers and STM32CubeMX to generate DMA Burst transfers from memory to TIM1 in OCToggle mode on the Nucleo F722ZE.

Old versions of the HAL drivers had a function called

HAL_StatusTypeDef HAL_TIM_DMABurst_MultiWriteStart(TIM_HandleTypeDef *htim,

                                                   uint32_t BurstBaseAddress,

                                                   uint32_t BurstRequestSrc,

                                                   uint32_t* BurstBuffer,

                                                   uint32_t BurstLength,

                                                   uint32_t BufferLength)

which is identical to the

HAL_StatusTypeDef HAL_TIM_DMABurst_WriteStart(TIM_HandleTypeDef *htim,

uint32_t BurstBaseAddress,uint32_t BurstRequestSrc,uint32_t* BurstBuffer,uint32_t BurstLength)

except the 

BufferLength
