SPI满足不了,工程师建议用GPMC接口或者PRU接口来实现。
That's about 26Mbytes/s, you will not be able to do that using a regular SPI interface.
If you really need that speed and given you are talking to an FPGA (that hopefully you can customize) the use of the GPMC interface…
Part Number: AM2434 Hi,
We refer to PRU-ICSS EtherCAT Slave Firmware Data Sheet and find that the Lowest cycle time of EtherCAT can reach 50us, as shown in the figure below.
However, in my test, the Lowest cycle can only reach 160us, and my master and…
