Cyclone V SoC FPGA boot from QSPI。 - Cyclone V SoC FPGA boot from QSPI。 I build a barematel program.I want boot this from QSPI flash. It can run well at DE1-SOC development board. BUT at our own PCB, it stop when HPS write FPGA PIO. Is it a boot problem? I stop here for a long time, hope your reply! Replies: Re: Cyclone V SoC FPGA boot from QSPI。 Hi!, Hoping you're doing well , please take a look at the following tutorial/documentation about how to boot from QSPI for Cyclone V and the Documentation for building your Bare-metal project properly. https://rocketboards.org/foswiki/Documentation/BuildingBootloader#Cyclone_V_SoC_45_Boot_from_QSPI https://rocketboards.org/foswiki/Documentation/SoCEDS#Cyclone_V_Bare_Metal_Example_Using_SoC_EDS_Standard_Edition regards, Replies: Re: Cyclone V SoC FPGA boot from QSPI。 Hi, Please take a look at the following documentation https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-v/cv_54012.pdf#page=1116 Regards, Replies: Re: Cyclone V SoC FPGA boot from QSPI。 nope I have a .PDF file. It record something that is wrong. But it is writen by chinese. I just present it for you. Replies: Re: Cyclone V SoC FPGA boot from QSPI。 Hi !
