Bootloader Update Error

Hi, Per checked internally, this is a bug that will be fixed in rel-32.6.1. If you want to stay on rel-32.5.1, the workaround is download l4t_payload_updater_t210.py from the NVIDIA Developer web site’s L4T 32.5 Archive to the Linux_for_Tegra directory. Then copy the file to its final location and make it executable: $ cd Linux_for_Tegra/ $ sudo cp <l4t_payload_updater_t210.py> rootfs/usr/sbin/l4t_payload_updater_t210 $ sudo chmod a+x rootfs/usr/sbin/l4t_payload_updater_t210

Also, please make sure that your need to use the same board config name when you create the BUP. I mean you need to use the same one as what you used in flash.sh.
