50 / 368 page  BootROM RM0319 50/368 Doc ID 022640 Rev 3 5.6.6 Parallel NOR Flash boot Parallel NOR on reset is always in read mode. Using this feature, we program the EMI controller with appropriate values tested in simulations. BootROM searches for X-Loader in Parallel NOR sector 0 and copies X-Loader to eSRAM. If any error occurs during parallel NOR boot, BootROM shifts to USB boot. Figure 13. Parallel NOR Flash boot Initialize EMI controller for NOR Search X - Loader in NOR X -Loader Found? YES NO USB boot Copy X -Loader to eSRAM Authenticate X- Loader? USB boot Jump to X - Loader in eSRAM Passed Failed Note : Boot type specification tells if it is 8-bit NOR or 16-bit NOR |
