hello,
I'm a new member here so if i am uploading this question in a wrong way please notify me.
i am working at the moment with octavo board OSD32MP15x that integrates the STM32MP15x dual core Arm cortex A7 and an arm cortex m4.
i am trying to run a simple example with HAL_SPI_TransmitReceive_DMA() just to transmit and receive the same byte every time. the code is not showing me any errors when building but when i use the logic analyser there is no data transmission or reception. i added the dma_rx and dma_tx requests using the the ioc file and working with the circular mode in both cases.
is there any suggestions as to what might be the reason behind it ?
PS: the same example with HAL_SPI_TransmitReceive() worked just fine.
thank you in advance!
