[FAQ] J722SXH01EVM: How to enable OSPI NAND & NOR boot on 9.2 Linux SDK

By default the 9.2 SDK for J722S does not support OSPI NOR & NAND boot modes. How to enable them?

    Hi,

    Yes it is possible with the below patches on top of the U-Boot directory of the 9.2 SDK. The only Caveat is that there is an issue with DMA with OSPI on 9.2 SDK.
    So we have disabled DMA with OSPI and hence the boot will be slower.

    j722s-ospi.tar

    Download the above tar file to SDK U-Boot folder & then follow the below instructions:

    cd $PSDK_Linux/board-support/ti-u-boot-2023.04+gitAUTOINC+f9b966c674
tar xf j722s-ospi.tar
git am j722s-ospi/*
cd ../..
make u-boot
cp build/a53/u-boot.img build/a53/tispl.bin build/r5/tiboot3.bin /media/$USER/BOOT/

    Boot to U-Boot prompt using SD boot mode:

    BOOTMODE [ 8 : 15 ] (SW4) = 0100 0000
    BOOTMODE [ 0 : 7 ] (SW3) = 1100 0010
    Follow the steps here to flash to NAND or NOR based on the need:

    For NAND boot change the dip switch settings:
    BOOTMODE [ 8 : 15 ] (SW4) = 0000 0000
    BOOTMODE [ 0 : 7 ] (SW3) = 1100 0000
    BOOTMODE [ 0 : 7 ] (SW2) = 1XXX XXXX
