DRA77P: DRA77p custom board bring up

Padmesh,

First you should use the PinMux Tool:

https://dev.ti.com/pinmux/app.html#/default

There's a link to a tutorial in the upper right corner if you've never used it before.  Once you're done you will download the genericFileFormatIOdelay.txt and genericFileFormatPadConf.txt files from the utility.  There's a perl script that is then used to convert those files into the proper format for use in u-boot.  The process is the same as what's described in this app note:

IODELAY Application Note for AM57xx Devices

The output of the perl script will be integrated into the mux_data.h file that is part of your board data.

Next you'll want to use the EMIF tools to calculate appropriate register configurations.  That's described in this app note:

AM57x, DRA7x, and TDA2x EMIF Tools
http://www.ti.com/lit/pdf/sprac36

You will need to integrate the corresponding structures into u-boot.

These are some of the key steps, so if you can get these completed and integrated, I think you'll be well on your way to a successful board bring-up.

I strongly recommend starting individual threads for specific questions/issues.  In other words, please don't use this one thread for all issues encountered as you bring up your board.

Best regards,
Brad
