AM6548: DFU function in AM6548

wan kun

Part Number: AM6548

We followed guide in https://software-dl.ti.com/processor-sdk-linux/esd/AM65X/latest/exports/docs/linux/Foundational_Components/U-Boot/UG-DFU.html

We use IDK evm board to verify this function, we meet some problems:

set boot code to boot from USB [3..0] to 1000, its mode and port we select mode 0(dfu function), USB0

connect our host with usb0 on IDK (PCIE extender board),

run command on host:

Hi,

You will have to am65x_evm_r5_usbdfu_defconfig to build your tiboot3.bn that can be used for DFU.

Rest all other images will be same.

Please try to compile the am65x_evm_r5_usbdfu_defconfig and use the tiboot3.bin obtained from that for DFU.

Best Regards,
Keerthy

Hi, Keerthy

I had replaced the tiboot3.bin from am65x_evm_r5_usbdfu_deconfig compiling process, but the result is the same as follow:

kenn@Precision-5530:~/tmp/uboot_6548$ sudo dfu-util -R -a bootloader -D tiboot3.bin
dfu-util 0.9

Hi,

dfu-util: can't detach
Resetting USB to switch back to runtime mode

Is not a fatal error.

Can you try 'sudo dfu-util -l' after the transferring tiboot3.bin. You should see the name of the next binary to be
transferred.

Keerthy

Please see the message that we try "sudo dfu-util -l" after sending tiboot3.bin:

Hi Kenn,

Are you using a ubuntu Virtual machine or a Ubuntu host machine?

Yes, We used a Ubuntu host machine， which the version of Ubuntu is 18.04

Thanks

Hi Kenn,

I am facing issues with my ubuntu VM with DFU. I will try to get a native Ubuntu host machine & try to reproduce the issue.

Hi Kenn,

On top of using the am65x_evm_r5_usbdfu_defconfig to build your tiboot3.bn
Please use the below DT change as well:

Hi, Keerthy

I modified it as your guide, but it still didn't work:

Kenn,

This issue is different. Earlier you were able to transfer tiboot3.bin.

Please check your connection.

Also the above diff is provided on top of 8.0 SDK.

In 7.3 SD you should change the dr_mode like below:

diff --git a/arch/arm/dts/k3-am654-base-board-u-boot.dtsi b/arch/arm/dts/k3-am654-base-board-u-boot.dtsi

Keerthy,

Yes, we built it on SDK 8.0. After we reconnect the usb line, now it can transfer three files successfully, but it failed at the last file u-boot.img transferring:

kenn@Precision-5530:~/tmp/uboot_6548$ sudo dfu-util -R -a u-boot.img -D u-boot.img

This is new 26th August. So this is all good.

This is old right? Aug 7th? Are you building the new tispl.bin & trying DFU?

Please build all the binaries fresh after the change in DT.

Use the latest built binaries. If this works please click on verify answer.

Keerthy

Thanks, Keerthy：

Yes, it worked， I just copied that tispl.bin and u-boot.img from the folder "prebuilt-images“ in SDK 8.0 yesterday， today I compiled it and it worked fine.

Thanks!
