I am trying to get U-boot on raspberry pi 4B, after plug in there is no output on TeraTerm or Putty. The yellow LED is blinks normally, but still nothing comes up on the screen. I have already made partition as FAT32 on my SD card and loaded below files. These are the steps I followed

  1. Cloning
  2. sudo apt-get install gcc-aarch64-linux-gnu
  3. export CROSS_COMPILE=aarch64-linux-gnu-
  4. make rpi_4_defconfig
  5. make -j$(nproc) Build gets successful with no errors. In config.txt I have enable_uart=1 arm_64bit=1 kernel=u-boot.bin (I have tried renaming u-boot.bin to kernel8.img) core_freq=250 device_tree=bcm2711-rpi-4-b.dtb

Please help me with some tips or guidance, so that u-boot will work on RPi4B.
