    L3, R3 --> Caps Lock, Middle Click

  • Added error checking at boot
    Fixes "bricks" where linux partition is corrupted but can be fixed
  • Creating .reinit file flag in switchroot/ubuntu will force a re-extraction of Kernel and Modules/Firmware
    That should always be used if user update BSP to another one (for example r32.7.3)
  • If initramfs fails booting it will try to dump kernel log in sd first (l4t_initramfs_kmesg.log) before showing the red screen.

Boot Stack changes

  • Careful with what you are booting on T210B01 since it can create hangs in black screen or error messages.
    Error message will be shown if that's the case, to avoid a black screen hang.
