enabling uuu support for imx7

vishnupratap_si — Mon, 07 Jan 2019 07:40:56 GMT

Hi,

I was trying to create linux kernel firmware binary with uuu support added.

As per the uuu user guide i enabled the FUNCTIONFS in kernel, but when i tried to run this kernel with uuu tool, i get below error -

mkdir: can't create directory 'functions/ffs.utp': Device or resource busy

i checked the functionfs is enabled and in windows it is detected as Functionfs also.

Any help will be appreciated.

Hi Vishnu

latest NXP Linux L4.14.78 uses uuu for programming, so one can check its documentation:

Linux L4.14.78_1.0.0 Documentation
https://www.nxp.com/webapp/Download?colCode=L4.14.78_1.0.0_LINUX_DOCS&appType=license&location=null
uuu documentation

Best regards
igor

Hi,

I had this issue, you could try disabling "USB Gadget precomposed configurations" in the kernel configuration.

Will.
