hi El,

May I know the process of the Linux compilation that was made? OR is this from a prebuilt image used from Rocketboards? Which Linux/version are you using?

-- not prebuilt image. compiled myself, linux version is Linux socfpga 4.14.73-ltsi, download from https://github.com/altera-opensource

compiler is download from linaro

Also, what was the booting method, via SD card, QSPI etc?

booting from NAND FLASH.

Was there any error/issue during the booting of preloader/u-boot? Can you share the boot logs for preloader,u-boot,kernel and Linux?

yes, of course, i will post it later. by the way, rootfs come from the EDS installation directory.
