boot from S25FL512S

Hi all,

I try to boot from QSPI Flash (S25FL512S) but I am having some difficulties.

I have the same DDR3 as altera cyclone v soc board + two QSPI S25FL512S connected to the hps side. Input clock for FPGA and HPS = 25MHz.

First, I followed the tutorial on rocketboard:

http://rocketboards.org/foswiki/view/documentation/gsrd131qspiboot

but the flash was not detected, then, I added these lines in u-boot spl file spansion.c 


   {
        .idcode1 = 0x0220,
        .idcode2 = 0x4d00,
        .pages_per_sector = 256,
        .nr_sectors = 1024,
        .name = "S25FL512S",
    },

but i still have a problem, the board reboot non stop with this log rather than going to u-boot

I have no idea, I have tried many things. I can boot with the arrow sockit but the flash is different.

there is something missing :/

I attached my quartus design.

thank you for your help

    Hi,

    I am working on cyclone V SOC custom board and i want to boot bare metal application from qspi flash(S25FL512S). I dumped the quad custom preloader image(preloader-mkpimage.bin) into the flash using the command "quartus_hps -c 1 -o PV -a 0 preloader-mkpimage.bin". I built the helloworld example bare metal application from GHRD and created the the bootable image using the commands,

    objcopy -I elf32-little -O binary hello.axf hello.bin

    mkimage -A arm -O u-boot -T standalone -C none -a 0x01000040 -e 0 -n "baremetal image" -d hello.bin hello.img

    I dumped the bootable image on qspi using

    quartus_hps -c 1 -o PV -a 0x60000 hello.bin

    After resetting the board(cold and warm reset) preloader prints are printed on console but hello world is not printed. Same problem with the hwlib example bare metal application.

    When i tried to boot uboot from qspi it is booting properly. I used following commands for that,

    mkimage -A arm -O u-boot -T standalone -C none -a 0x01000040 -e 0 -n "U-Boot image" -d u-boot.bin u-boot.img

    quartus_hps -c 1 -o PV -a 0x60000 u-boot.img

    I am wondering why i am not able to see any bare metal application prints on console. Any help would be greatly appreciated.
