    Hello, I tried your solution, but I am doing something wrong, flashcp doesn't output nothing. Is that right? When I connect HDD and try to boot, I get error

    Trying to boot from sunxi SPI
    No matching DT out of these options:
       Configuration to load ATF before U-Boot
    No matching DT out of these options:
       Configuration to load ATF before U-Boot
    SPL: failed to boot from all boot devices
    ### ERROR ### Please RESET the board ###

    What am I doing wrong?

    What do you mean by "new procedure" ?

    Previously this year I asked about boot from USB without SD card. Solution was flashing u boot to spi flash. With this new image doesn't work. So I would like to know how to update u boot on SPI so it will boot from USB without SD card.

    Thanks

    Hello,

    finally I understood what do I have to do. I have checked timings with .bin via fex. Then I recompiled kernel and installed to SD card. But I have problem: when I check via fex I get resolution 1280x720 instead of monitor's 1280x800. I have compiled with 720p, but the picture isn't sharp, but when I change 720 with 800 I don't get picture. Please help.

    Hello,

    I have another issue, only on 720p and 1080p is picture with normal colours. On other is green and pink, so it doesn't work.

    Reply on previous comments: I have checked this topics, but I haven't found where is this patch put? In which directory?

    I have also tried SD card with h3 disp helper, but it didn't boot, probably because is made in VM. Is there another solution for Windows image burner?

    I am complete newbie on LCD timings, so please help me.

    Yes, should be either 

    
dd if=u-boot-sunxi-with-spl.bin of=/dev/mtd0block

    or 

    
flashcp u-boot-sunxi-with-spl.bin /dev/mtd0

    flashcp is present in the "mtd-utils" package

    Thank you very much! The flashcp made the work. I didn't know to what package is this utility included, since that dd did nothing. Thanks again.

    Not exactly "usable", but possible to use.

     

    First, write the u-boot (u-boot-sunxi-with-spl.bin located somewhere in /usr/lib/linux-u-boot-dev...) to the SPI flash, either with dd to /dev/mtd0block or with flashcp to /dev/mtd0. No offsets are needed for dd.

    Second, write a fresh image to the USB HDD. Old images (even after upgrades) or installed with nand-sata-install may not work and were not tested.

    Third, shut down the board, remove the SD card, power it on and hope that your HDD spins up fast enough. U-boot has a timeout for detecting USB devices that AFAIK can be changed only with recompilation and if HDD spins up long enough it won't be detected.

     

    If there are any questions or issues, they will not be looked into without a log from the serial console.

    dd if=u-boot... of=/dev/mtdblock

    Is this right command?
