I tried to use a clear Jetson-Nano-Tegra210_Linux_R32.1.0_aarch64.tbz2 just now. The result did not change.
Step 1: uncompress Jetson-Nano-Tegra210_Linux_R32.1.0_aarch64.tbz2
Step 2: uncompress Jetson-Nano-Tegra_Linux_Sample-Root-Filesystem_R32.1.0_aarch64.tbz2
Step 3: run “sudo ./apply_binaries.sh”
Step 4: uncompress nvtboot.tar.gz downloaded from #40 and put nvtboot.bin to Linux_for_Tegra/bootloader/t210ref, nvtboot_recovery.bin to Linux_for_Tegra/bootloader
Step 5: modify jetson-nano-qspi-sd.conf
Step 6: set Nano to RCM
Step 7: use command “sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1” to flash
