SK-AM62A-LP: SK-AM62A-LP 的SD卡引导启动失败

Part Number: SK-AM62A-LP


用sdk包中的filesystem里的wic镜像写入sd卡,可以启动

但是自己编译的uboot、kernel、dtb镜像,写入sd卡启动不起来,报如下错误,找不到设备树

我的步骤是:

1.对SD卡分区,两个分区(boot分区、rootfs分区)
2.编译boot分区镜像
make u-boot
export TI_SECURE_DEV_PKG=<path-to-board-support>/core-secdev-k3
make sysfw-image DEVICE_TYPE=hs-fs

拷贝启动镜像到boot分区
sudo cp board-support/k3-image-gen*/tiboot3-am62*-hs-fs-evm.bin /media/$USER/boot/tiboot3.bin
sudo cp board-support/u-boot_build/a53/u-boot.img board-support/u-boot_build/a53/tispl.bin /media/$USER/boot

3.编译内核
make linux
将内核镜像、dtb拷贝到rootfs分区的boot目录
sudo DESTDIR=/media/$USER/rootfs make linux_install

4.make linux-fitimage
将fitimage拷贝到rootfs分区的boot目录
sudo DESTDIR=/media/$USER/rootfs make linux-fitimage_install

确认文件已拷贝过去,无误
