Following your advice, I checked the DMA registers and found that they were not set to the intended values. After the HAL_SPI_Init () function, the contents of hspi-> hdmatx were rewritten. Changing the order of the code worked fine. Thanks for the a...

When I checked the TX data by logic analyzer, it changed as follows.data: [0x00,0xF8,0x00,0xF8,...]// SPI_DATASIZE_8BIT, DMA_MDATAALIGN_BYTE, DMA_PDATAALIGN_BYTE, DMA_MINC_ENABLE... 00 F8 00 F8 00 F8 00 F8 ...// SPI_DATASIZE_16BIT, DMA_MDATAALIGN_HAL...
