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. https://github.com/SatishKumarReddyPokala/RPI4/tree/master/U-Boot/Build_U-Bo... https://archlinuxarm.org/packages/armv7h/uboot-raspberrypi/files/PKGBUILD

Hi,
I'm porting u-boot for raspberry pi 4. I cross compiled u-boot for Raspberry pi 4 and copied u-boot.bin and latest firmware files start4.elf and fixup4.dat from git into a SD card. My configuration file contains enable_uart=1 arm_64bit=1 uart_2ndstage=1 kernel=u-boot.bin
Inserted SD card into pi and started monitoring logs from serial port. it got stuck at starting start3.elf @ 0xfec00200 I am not able to find the solution for this issue. Please kindly help to resolve this u-boot bug in raspberry pi 4.
