Writing a T1040 Bootloader

[john_truscott2]

Hello,

We have a T1040R4RDM dev board and need to write our own bootloader to replace u-boot. and subsequently run our application. The ultimate target will be a bespoke board.

Does anyone have any guides or tutorials on how to do this?

We are working our way through the data sheets and reference manuals but any help in this area would be much appreciated.

Many thanks

John

The only software solution for T1040 provided by NXP is Linux SDK.

There are no guide or tutorial concerning bootloader development because the SDK uses U-Boot.

General U-Boot initialization flow is as follows:

For all processor- and board-specific initializations it is possible to refer to the U-Boot sources in the Linux SDK v2.0:

Hi Ufedor,

Thanks for the reply, I've started looking at the U-Boot code. Is the document you extracted that page from included in the SDK download or can you supply a link to it please?

Cheers

Excuse me, this is a single overview picture - there is no complete document describing U-Boot operation in detail.
