    Hi,

    Are you using OSPI as the boot media? If yes you will need to run sf probe before booting Linux. It is a known issue.

    Hi Ruijie Sun,

    root@j7-evm:~# cat /proc/mtd
    dev: size erasesize name
    mtd0: 00080000 00020000 "ospi.tiboot3"
    mtd1: 00200000 00020000 "ospi.tispl"
    mtd2: 00400000 00020000 "ospi.u-boot"
    mtd3: 00040000 00020000 "ospi.env"
    mtd4: 00100000 00020000 "ospi.sysfw"
    mtd5: 00040000 00020000 "ospi.env.backup"
    mtd6: 03800000 00020000 "ospi.rootfs"
    mtd7: 04000000 00010000 "47050000.spi.0"

    I am on the latest 8.2 SDK but I believe 8.1 also should be working.

    Are you using some custom Device tree changes or using the default SD card?
