Boot Process
The FPGA configuration for Intel MAX 10 FPGAs can be stored through JTAG interface either in external configuration device (QSPI flash memory U5) or on the FPGA itself since the Intel MAX 10 FPGA offers non-volatile memory on chip. The FPGA configuration is loaded from the non-volatile memory when the board is powered up.
To configure the FPGA directly, the JTAG interface can be used to configure the FPGA volatile, means the configuration is lost after power off.
