Parallel NOR-Flash of 16bit BUS and IVT data

[tamotsu]

Hellow.

On page 1241 of the i.MX7D reference manual, the IVT header format diagram suggests that the value to be set would be 0xD1-0x0020-0x40 to .word 0xD1002040, but in the 20132 "i.MX6 IVT structure" Anson Huang answers that it should be .word 0x402000D1.

I think the manual says this is

0x400 = 0xD100

0x402 = 0x2040

but is that wrong?

Thank you.

Hi, 

tag = D1 is the first byte. The difference as Anson's should be caused by display options, like endian.

Thank you Harvey021.

So Anson explained it in little-endian?

I'm confused because the reference manual says it's big-endian.

The header ivt should be included in image by default, we don't need to modify it.

And we can try to dump it using command od w/t option little or big endian

od -x -N 48 --endian=little u-boot.imx 

or

od -x -N 48 --endian=big u-boot.imx
