I am trying to communicate with a wifi module with stm32f769's spi interface. My data packet is 64 bytes, but the spi only provides 16 clock cycles, Hence the datapacket sent is invalid. Can anyone tell me what could be the possible solution for this...

Hi, I am using stm32f769Ni evk for a project. Here I am interfacing stm32 with a wifi module using spi dma . The communication fails during reception with HAL_SPI_ERROR_DMA after /* Enable the Tx DMA Stream/Channel */ if (HAL_OK != HAL_DMA_Start_IT(...

can anyone help me to know the reason for this unusual behavior or what am I missing here.

Did anyone solved this? I am having the same issue in my custom board.

The issue is very random and it rarely happen when I put breakpoints. It happens after __HAL_DMA_ENABLE(hdma); call

Hi Bouraoui,Yes, I have referred this example. The issue is very random and it rarely happen when I put breakpoints. It happens after __HAL_DMA_ENABLE(hdma); call

Thanks for the reply waclawek.jan . The USART pins which are enabled when USART2 is configured through stm32cubemx are PA2 for Tx and PA3 for Rx. But VCP Rx is port PA15. We need to set PA15 as USRT2 Rx from cubemx. This solved my issue.

SPI only gives 16 clock cycles, but my data is 64 bytes

HAL_SPI_ERROR_DMA

I am currently working with the stm32 Nucleo-432KC board.uart2 receive doesn't seem to receive any data which is sent through the PC terminal. But uart1 receive seems to work fine.
