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. Regards, Satish
