Part Number: TMS320F28377D

Hi,

Why burst size cannot over 8 when SPI use DMA ?

The results were wrong when I use burst size cannot over 8.

I found that example code (Example_2837xS_Spi_dma.c ) comment " burst size should be less than 8"

thanks,

best regards,

Simen

Hi Simen,

Please refer section "18.3.8 SPI DMA Transfers" of device TRM for more detail about SPI <-> DMA interface.
