AM5728: How to rebuild u-boot FIT image for Android SDK

John Lindgren

Part Number: AM5728

Hi,

In the Android SDK for the AM5728[1], it's possible to rebuild the Linux kernel using "make linux".

However, this only rebuilds the zImage. The u-boot FIT image (boot_fit.img) is not updated.

What is the best way to rebuild the boot image to include the new kernel? Is it possible to do this without rebuilding the entire SDK?

Hi John,

Can you take a look at this:

mkdir fit_img

cd fit_img

cp $(KERNELDIR)/arch/arm/boot/zImage .

cp $(KERNELDIR)/arch/arm/boot/dts/ti/*.dtb .

cp $(KERNELDIR)/arch/arm/boot/dts/ti/*.dtbo .

cp out/target/product/beagle_x15/ramdisk.img .

cp device/ti/beagle_x15/beagle_x15.its .

mkimage -D "-I dts -O dtb -p 500 -Wno-unit_address_vs_reg" -f beagle_x15.its boot_fit.img

give it a try
