I use ti-TMS320C6678 and K7 FPGA in the project to communicate with SRIO. I need to connect to 4X. After the initialization is completed, I can find the connection mode from 4X to 1x by querying the “SPnCTL” register on the DSP side. In the process, I need to guarantee 4X connection can guarantee the transmission bandwidth. How to ensure that 4x becomes 1x after initialization and reinitialize to 4X?
