AM62A7-Q1: how to flash the kernel and filesystem into Nandflash

Hi Meng,

First please follow the instruction linked below to create the rootfs UBI image.

https://software-dl.ti.com/processor-sdk-linux/esd/AM335X/09_01_00_001/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Storage/NAND.html#nand-based-file-system

Next load the UBI image file to DDR from whatever media/interface available on your board. Then write the rootfs image:

=> mtd write spi-nand0 ${loadaddr} 0x2000000 ${filesize}
