Hello everyone,
I'm asking when the processor Imx7 send a signal to FPGA max 10. How could I capt the signal and then decode it?
Could anyone help me please, thanks a lot

This really depends on what sort of signal! Are you looking at treating the FPGA as a SPI slave, using SPI for communication? CAN? I2C? UART? Or a generic data/address bus using a custom driver and GPIO? Maybe even reusing a QSPI interface and treating the FPGA as memory?
In short, if you're just talking about a single line, then you want to register the signal in the FPGA once you get it with some sort of if(rising_edge(clk)) statement, unless you're trying to do something special.
Details would really help.
