u-boot usb command

[shanlan123]

I want to use usb command in u-boot of s32g2, but there is no usb command in u-boot of s32g2.
Is there a compiled u-boot that can solve this problem? Or Is there a document that teaches me how to compile a u-boot with usb command?

I am use s32g274a_rdb2

Hi @shanlan123,

u-boot USB command is available in the u-boot repo. 

Find the path where the u-boot command handler for USB is written in the u-boot source code:

cmd/usb.c

you can modify and create new commands as per your requirement in the same.

Please find the attached screenshot for your reference.

Thanks,

I have done that, but when I type "usb start", it print "No working controllers found"
