Linux/PROCESSOR-SDK-DRA7X: Adding DFU to U-Boot

James Brandon

Tool/software: Linux

Hi.

I am trying to load code onto emmc attached to a J6 processor using DFU mode.
I am attempting to build a version of the u-boot-spl with DFU enabled.

I am looking mainly at this document here:

Which U-Boot repository should I be using to have the "dra7xx_evm_usbboot_config" in it?
All of the ones I have found including the ti one (git://git.ti.com/ti-u-boot/ti-u-boot.git) seem not to have it.

Thanks

Hi James,

I have forwarded your question to U-boot experts.

The document you are referring based on GLSDK 7.01 version. This has changed quite bit on latest version.

In U-boot, DFU is already supported, refer to

In order to use DFU in SPL (MLO or single stage boot loader), you can enable SPL-DFU feature refer to

Hi Ravi.

Thanks for that I am now working with the latest u-boot repo: uBoot Version: ti-u-boot-2017.01

I am trying to get enable DFU in SPL support to flash the rawemmc

I have followed the guide you linked (processors.wiki.ti.com/.../Processor_SDK_Linux_Automotive_Software_Developers_Guide

But following this line
select SPL->DFU support from menuconfig->"Boot Images"->"Enable SPL with DFU to load binares to memory device"
Is not possible as "Enable SPL with DFU to load binares to memory device" is not an option within boot images.

How can I add this option, is there a patch compatible with the branch I am using?

Thanks
James.

The above reference is based on 2016.05 u-boot.

Did you check this section processors.wiki.ti.com/.../Linux_Core_U-Boot_User's_Guide
