Part Number: TMS320F28377D Tool/software: On the DSP28377D chip, I use DMA to store the data received by SPI. I read that the DMA storage address has increased by the number of received data, but when I read the data in the DMA storage buffer, I found that it has not been updated. I have to wait for 238 clock instructions before the data is refreshed. I modified the buffer with the violation keyword but it didn't work. Is this caused by the hardware or I didn't handle it properly? I want to know the exact time point of the data refresh.
