Tool/software:
When I use the emif of tms320c6748, I use two chip selectors, chip selector 2 and chip selector 4, both connected to FPGA. Chip selector 2 is used to transmit real-time data, and chip selector 4 is used to transmit non real time data. I use EDMA for reading and writing of chip selector 2, so it will not be inserted by the read and write of chip selector 4 at all. However, occasionally during the write of chip selector 2, the read and write of chip selector 4 will be inserted in the middle. I don't quite understand why during the read process of chip selector 2, chip selector 2 will not be inserted by the read and write of chip selector 4 at all. During the write process of chip selector 2, it will be inserted by the read and write of chip selector 4. I hope that the write process of chip selector 2 will not be inserted either.
