FB commands not running on IMX-28

[ahsan-kaukab]

Hello, I have been working on IMX-28EVK and installed the uuu and when I connected the IMx28 controller I can see it using uuu -lsusb

When I try to run SPDS commands its running fine

But the problem occurs when I try to run FB / FBK commands and the IMX board gives an error [Bulk(W):LIBUSB_ERROR_IO ] FB: ucmd echo as follow:

also the auto file content is as follow:

Also the WinUSB drivers on my imxboard is as follow

The idea is that I have to update the splash screen on my IMX-28 using uuu utility and uboot command but FB and FBK is not working on IMX28-EVK , any one can help me with this issue ?

I have tested it using Win10 and Ubuntu 22.0

I am not sure how old your imx28 uboot. Some fastboot patch need be backport

Can you specify how to add a patch and build uboot for IMX28, according to another forum :: I can see that uboot can be customized using CE-6 and VS-2005 which is not supported in Win10. Also Plz send the link of the patch to add to uboot

I have source code of uboot but not able to build it on win-10 / ubuntu-20 because I can not see a good way of building uboot for imx28

It is too old. I can't remember exactly. It is similar with other uboot, you can good it. The only difference is, iMX28 need a tools to call elftosb to convert uboot to ROM supported format.
