inside Source code of Ibl you have used only three boot mode ethernet , nor and nand.

Can any one Tell me PCIe comes under nor boot or nand boot. (why).

Sorry If it is too silly...

The IBL is an intermediate boot loader. The ROM boot loader is the main boot whihc supports all the boot. The IBL supports mainly NOR, NAND and TFTP boot only. The PCIe boot supported only by ROM boot loader.

hi Arun

Do you mean to say no Need of IBL in PCIe boot

( ROM BOOT ) ----+--> ( IBL ) ------>( Application )

+---> (PCIe BOOT) -----> (Application)

(((((( Where is NAND and NOR in this Picture ))))))

Actually just now I am writing IBL in le mode and using DIP switch to put the board in PCIe mode.

There is some code in IBL source that is defining PCIe base Address ?????????

Thanks

Yes. The flow will be

ROM Boot ----> PCIe Boot ---> application.

Thanks,
