Re: U-boot command prompt failed to load in Raspberry pi 4

Hi, I found that there is a change in building U-Boot for Raspberry pi 4. 1. Kernel address space is increased. 2. Need to add respective *.dtb files to the /boot. 3. boot.src and boot.txt files were added to the /boot. Please refer to the following links for more information.
