Hello!
Trying to launch SPI via DMA data transfer to LCD display. I has created "default" project via cube master.
Created SPI2 for LCD display in 8bit Master Transfer Only mode.
Added DMA1 Stream 0 to SPI2_TX Mem to Perif.
In code I do:
static uint8_t buff[28800] __attribute__ ((aligned (32))); //in result buff in RAM_D1 - i have checked it.
MX_SPI2_Init();
MX_DMA_Init();
....
HAL_SPI_Transmit(&hspi2, buff, chunk_size, HAL_MAX_DELAY); // This Code work FINE.
....
HAL_SPI_Transmit_DMA(&hspi2, buff, chunk_size); //This Code NOT work.
No I or D caches are enabled in Cube.
How to make it work? :tired_face:
