udc-core: couldn't find an available UDC or it's busy

[rakeshk7097]

Hi team,

while running the rdinit=/linuxrc giving as args in the u-boot i am getting the below error.

udc-core: couldn't find an available UDC or it's busy ./linuxrc: line 143: echo: write error: Device or resource busy uuc /dev/utp

and seems because of it the UUU FBK command is not working .

Please suggest on this issue .

Regards, Rajeshi

Check your dts file and boot load. USB controller driver probe failure or deferred. Most common failure reason is some depentence device node probe failure, such gpio expender, or i2c, PTN5150 type C chip driver
