Hi , I have recently purchase a evk for i.mx8m nano platform. Trying to bring up the board following this : [https://www.digi.com/resources/documentation/digidocs/embedded/dey/3.2/cc8mnano/yocto-gs\_t\_program-fw](https://www.digi.com/resources/documentation/digidocs/embedded/dey/3.2/cc8mnano/yocto-gs_t_program-fw) The uuu script is waiting infinitely for the USB device detection , even though rules step has been done correctly also device is in fastboot mode. Not sure what is the problem. Still suspecting the u-dev rules, but was not able to find anything there too. ---

Does it work if you use a microSD card to install the firmware directly in the target? Have you verified that the cable you are using is working? ---

Hi , Thanks for answer. It boots successfully via SD card. I am pretty sure I am using molex cable provided in the Kit. Still cannot boot over USB.
