Dear TI.
Our platform is j721s2, SDK 8.0.4.
First, I written tiboot3.bin tispl.bin and u-boot.img into emmc with DFU. Upgrade succeeded.
Then, I boot device from eMMC and made it into fastboot mode to flash rootfs with fastboot_flash.bat
Fastboot flash failed

But with the same method, the j721e platform can successfully upgrade the emmc.
Please help to check why j721s2 failed to fastboot flash eMMC.
Thanks.
