Mengapa boot Intel® Arria® 10 SoC saya tidak menggunakan mode boot FPGA ketika semua I/O khusus tidak digunakan?

Karena masalah pada Perangkat Lunak Intel® Quartus® Prime Pro/Standard, port input OSC_CLK_1_HPS, nPOR_RST, dan nRST_HPS dinonaktifkan oleh pengaturan boot U.

1) Pindah ke folder hps_isw_handoff dalam desain Anda.

2) Buka hps.xml

3) Temukan bagian berikut.
