3 Experiment

Two sets of boot images are required to validate the proposed redundant boot approach, one for primary boot and another for backup boot. The primary components used for validation include the following binaries:

  • Secondary Bootloader (SBL)
  • app (bootapp)
  • TI Foundational Security (TIFS)

For simplicity, QNX OS is selected as the high-level operating system (OS). To boot into the QNX console, the following binaries are required:

  • lateapp1, lateapp2
  • atf_optee.appimage
  • ifs_qnx.appimage
