Boot ROM code

[eishishibusawa]

Dear Sir

I would like to confirm the boot ROM code of i.MX6Dual.

The customer system boots from the parallel NOR (with Linux).

Q1.

What does it execute with Boot ROM code?

Is there any document that explained it?

Best Regards,

Eishi SHIBUSAWA

Hi Eishi

it is explained in sect.8.5.1.1 NOR flash boot operation i.MX6DQ Reference Manual:

Booting from the NOR flash is supported via the EIM interface. The ROM reads the
Image Vector Table and Boot Data structures to determine if the image can be executed
directly from the EIM address space or copied to another memory.
